MORE-INFO     CONCLUSION     BOTTOM-of-PAGE

INTRODUCTION :

In 2019 October, I 'upgraded' an Acer desktop computer with the Ubuntu-MATE 16.04 Linux operating system (previously installed) --- to Ubuntu-MATE 18.04.

    Ubuntu-MATE 16.04 is a 2016 April release.
    Ubuntu-MATE 18.04 is a 2018 April release.
    Both are 64-bit LTS ('Long Term Support') releases

That Ubuntu-MATE (Wikipedia link) upgrade-install is described on an

Ubuntu-MATE 18.04 INSTALL NOTES on Acer Desktop (2019 Oct) page
(not avialable yet, in August 2021).

Among the applications on the Ubuntu-MATE (Linux) Acer desktop computer was the SeaMonkey web browser (Wikipedia link) --- version 2.49.2, released in 2018 Feb.

In 2020 March (and 2021 June), I did an upgrade (and data migration) of a Windows7-Dell desktop computer to a Windows10-HP desktop computer.

That data migration included the migration of SeaMonkey (circa 2011 release) bookmarks on the Win7 computer to SeaMonkey (circa 2020 release) on the Win10 computer.

    That Win7-Dell to Win10-HP data migration was described on a Dell-to-HP Data Migration (2020-2021) page.

    However, the 'preferences'-settings in the old SeaMonkey (circa 2011) on the Win7-Dell computer were not recorded on a web page.

When I was doing the installation of a recent release of SeaMonkey on the Win10-HP desktop computer --- and when I was preparing to do the migration of SeaMonkey (circa 2011 release) 'bookmarks' to SeaMonkey (circa 2020 release) on the Win10-HP desktop computer --- I realized it would be good to record the 'Preferences' settings of SeaMonkey on one of my computers.

This page is intended to record the 'Preferences' settings of SeaMonkey 2.49.2 on my Ubuntu-MATE 18.04 Acer desktop computer --- as they were set on 28 August 2021.

This page is meant to serve as a guide-and/or-comparison to the SeaMonkey settings on the Win10-HP computer (or any Windows or Linux computer in the future).


'Preferences' categories:

To get to the 'Preferences' window in SeaMonkey 2.49.2, I used the toolbar path

  Edit > Preferences

There are eight (8) preferences 'categories' shown in a list on the left of the 'Preferences' window. These 'categories' can be 'opened' to show 'sub-categories'.

Each 'category' name (and 'sub-category' name) corresponds to a 'panel' of preferences (checkbuttons, radiobuttons, entry-fields, etc).

The 8 'main' categories (panels) are 'depicted' below --- along with sub-categories (sub-panels) for the several main categories that correspond to features that I use.

  1. Appearance
    • Content
    • Fonts
    • Colors
    • Spelling
  2. Browser
    • History
    • Languages
    • Helper Applications
    • Location Bar
    • Internet Search
    • Tabbed Browsing
    • Link Behavior
    • Downloads
  3. Mail & Newsgroups
  4. Calendar
  5. Composer
  6. Privacy & Security
    • Private Data
    • Cookies
    • Images
    • Popup Windows
    • Passwords
    • Master Passwords
    • SSL/TLS
    • Certificates
  7. Sync
  8. Advanced
    • Scripts & Plugins
    • Keyboard Navigation
    • Find As You Type
    • Cache
    • Offline Apps
    • Proxies
    • HTTP Networking
    • Software Installation
    • Mouse Wheel

    The main 'categories' that I tailor are 'Appearance', 'Browser', 'Privacy & Security', and 'Advanced'.

    I do not use 'Mail & Newsgroups', 'Calendar', 'Sync', or 'Composer'.

    I use the Thunderbird mail client (Wikipedia link) instead of SeaMonkey-Mail.

    And I use a text-editor --- such as SciTE (Wikipedia link) --- instead of SeaMonkey-Composer, to make web pages.

    I do not use SeaMonkey-Calendar and I do not choose to 'Sync' SeaMonkey 'across all my devices'.

The 8 link-sections below show important (to me) settings in each of these 8 'Preferences' panels - and their sub-panels ---

especially in the 4 sections: 'Appearance', 'Browser', 'Privacy & Security', and 'Advanced'.


Panel-depiction conventions:

Instead of using screen-captures of the many panels (and sub-panels), in the sections below, I have used the following conventions:

    Titles and labels on the panels are denoted by single-quotes around the text strings.

    Text strings that I have added as comments are generally enclosed in parentheses or brackets.

    Entries in 'entry fields' are generally shown after a colon (:) at the end of the label-string for the entry field.

    A checkbutton that is checked will be denoted by 'C-YES' before its label-string.

    A checkbutton that is unchecked will be denoted by 'C-NOT' before its label-string.

    A radiobutton that is selected will be denoted by 'R-YES' before its label-string.

    A radiobutton that is not-selected will be denoted by 'R-NOT' before its label-string.

    A list selection will be denoted by 'LIST:' followed by the label-string of an item selected in the list.

    Besides section-titles, a few of the items --- such as some 'Privacy & Security' and 'Advanced' settings --- may be shown in bold, because they are an important option setting that can be used to help minimize the likelihood of computer hacking or identity theft.


These notes can serve to help me check the 'Preferences' in any newer release of SeaMonkey --- on any computer, Microsoft Windows or Linux --- especially after the migration of SeaMonkey bookmarks.

Enough of this introduction. A description of the SeaMonkey 2.49.2 'Preferences' follows.

    BUTTON: 'Choose File...'
    BUTTON: 'Use Current Page'
    BUTTON: 'Use Current Group'
    BUTTON: 'Restore Default'

    (I may have set 'duckduckgo.com' as the Home-group by going to that page and then using the 'Use Current Page' button.)


Browser-History sub-panel:

'Browsing History'

    'History is a list of previously visited pages.'   BUTTON: 'Clear History'

You could use 'Add...' to add more languages.)

'Text Encoding for Legacy Content'

    'Used for legacy content that fails to declare its encoding.'

    'Fallback Text Encoding:'   LIST: 'Default for Current Locale'
    (Other items in the list are about 15 languages.)


Browser-Helper-Applications sub-panel:

(There is an ENTRY FIELD for 'Search Types and Actions':
blank with a magnifiying-glass icon on the right)

'Content Type' 'Action'
'binary/octet-stream type' 'Always ask'
'CSV document' 'Always ask'
'EXE file' 'Always ask'
'Gzip archive' 'Always ask'

'raw CD image' 'Always ask'
'Video podcast' 'Preview in SeaMonkey'
'WAV audio' 'Always ask'
'Web Feed' 'Preview in SeaMonkey'
'Zip archive' 'Always ask'

(When you click on the Action, such as 'Always ask', a drop-down menu of options appears and SeaMonkey does a pretty good job of offering suitable options for the 'Content Type'.)

    (For example, for 'WAV audio' the menu shows:)
    Save File
    Use VLC media player
    Use paplay
    Use other...
    Application details...

    (For example, for 'MP3 audio' the menu shows:)
    Save File
    Use VLC media player
    Use totem
    Use other...
    Application details...

    For example, for 'MPEG-4 video' the menu shows:)
    Save File
    Use Videos
    Use other...
    (One could use 'Use other...' to choose another movie player, such as 'SMplayer'.
    'Videos' is the Gnome movie player, probably forked from 'totem'.)

    (And for 'PDF document' the menu shows:)
    Save File
    Use SeaMonkey
    Use other...
    (One could use 'Use other...' to choose the MATE 'Atril' PDF reader.)

    (And for 'EXE file' the menu shows:)
    Save File
    Use
    Use other...
    (A '.exe' file is almost always a Microsoft executable.
    You generally would not choose 'Use' on a Linux distro.)


Browser-Location-Bar sub-panel:

'Autocomplete'

    C-NOT 'Automatically suggest websites from History'

    C-NOT 'Automatically suggest websites from Bookmarks'

    C-YES 'Highlight web pages with a high level of connection security'

'Unknown locations'

    C-NOT 'Perform a web search when entered text is not a web location'
      (Turning this OFF helps avoid accidental unneeded processing.
      To do a web search on text, one could use a search engine
      from your Bookmarks, say on the 'Bookmarks Toolbar.)


Browser-Internet-Search sub-panel:

'Default search engine'

    'Search using:'   LIST: 'DuckDuckGo'
      (Other options in this list are:
      'Google', 'Yahoo', 'Wikipedia')

    BUTTON: 'Manage Search Engines...'

'Search results'

    C-NOT 'Open new tabs for sidebar search results'

    C-YES 'Open a tab instead of a window for a context menu web search'

    C-NOT 'Open the Search tab in the sidebar when a search is invoked'

      (You may want to 'personalize' these seach-tab settings   with different choices.)

    C-YES 'Hide the tab bar when only one tab is open'

    C-NOT 'Switch to new tabs opened from links'

      (You may want to turn this OFF.)

'Open tabs instead of windows for'

    C-YES 'Middle-click, Ctrl+click or Ctrl+Enter on links in a web page'

    C-YES 'Ctrl+Enter in the Location bar'

      (You may want to turn these OFF.)

'Open in a new tab instead of a stand-alone window'

    C-NOT 'Data Manager'

    C-YES 'Add-ons Manager'

Browser-Link-Behavior sub-panel:

'Link open behavior'

  'Open links meant to open a new window in:'

    R-NOT 'The current tab/window'

    'Remove download entries'   LIST: 'Never'
      (Other options are:
      'When they have completed' and 'When quitting SeaMonkey')

'When a download completes'

    C-NOT 'Play a sound'

    C-YES 'Show an alert'

3. Mail-and-Newsgroups panel

(Since I do not use SeaMonkey-Mail or SeaMonkey-Newsgroups, I do not show the 'preferences' for this category of SeaMonkey-preferences.)

4. Calendar panel

(Since I do not use SeaMonkey-Calendar, I do not show the 'preferences' for this category of SeaMonkey-preferences.)

5. Composer panel

(Since I do not use SeaMonkey-Composer, I do not show the 'preferences' for this category of SeaMonkey-preferences.)

6. Privacy & Security panel
(and sub-panels)

'User tracking'

  'Websites may track how you use them, thus affecting your privacy.'

    C-YES 'Tell websites that I do not want to be tracked'

    R-NOT 'Disable this feature and deny all requests'
      (Choose this instead?)

'Safe Browsing'

  'SeaMonkey can block websites reported to contain malicious content.'

    C-YES 'Block reported attack sites (malware, viruses)'

    C-YES 'Block reported web forgeries (Phishing)'

      (Best to set these ON even if they incur extra processing
      and slow down response time.)


Privacy-Security-Private-Data sub-panel:

'Clear Private Data'

    C-YES 'Always clear my private data when I close SeaMonkey'

    C-YES 'Ask me before clearing private data'     BUTTON: 'Clear Now...'

    'When I ask SeaMonkey to clear my private data, it should erase:'

      C-YES 'Download History'

      C-YES 'Saved Form and Search History'

      C-YES 'Cache'

      C-YES 'Cookies'

      C-YES 'Offline Website Data'

      C-YES 'Saved Passwords'

      C-YES 'Authenticated Sessions'

(NOTE:
It is best to erase all this data so that, in case a virus is on your computer --- or some phishing attack is attempted, it does not have this data available to collect.
You should keep your passwords elsewhere.)


Privacy-Security-Cookies sub-panel:

'Cookie Acceptance Policy'

    R-NOT 'Block cookies'

    R-YES 'Allow cookies for the originating website only (no 3rd-party cookies)'

    R-NOT 'Allow third-party cookies for previously visited websites only'

    R-NOT 'Allow all cookies'

    (NOTE:
    When you are going to a website that seems to do all kinds of obnoxious/suspicious stuff, it is advisable to use Edit-Preferences to choose "Block cookies". Then set it back for websites, like Twitter, that will not work if you block all cookies.)

'Cookie Retention Policy'

    R-NOT 'Accept cookies normally'

    R-YES 'Accept for current session only'

    R-NOT 'Accept cookies for'   LIST: '90' 'days'

'Manage Cookies and Sites'

    Allows you to view and manage stored cookies and per-website settings for accepting and rejecting cookies. Per-website settings will override the settings above.

BUTTON: 'Cookie Manager'


Privacy-Security-Images sub-panel:

'Image Acceptance Policy'

  'Specify how SeaMonkey handles images.'

    R-NOT 'Do not load any images'

    R-NOT 'Only load images that come from the originating server'

    R-YES 'Load all images'

    BUTTON: 'Manage Permissions'

'Animated images should loop'

    R-YES 'As many times as the image specifies'

    R-NOT 'Once'

    R-NOT 'Never'


Privacy-Security-Popup-Windows sub-panel:

'Popup Windows'

    C-YES 'Block unrequested popup windows'     BUTTON: 'Manage Permissions'

    'When a popup window has been blocked:'

      C-NOT 'Play a sound:'

      C-YES 'Display an icon in the browser status bar'

      C-YES 'Display a notification bar at the top of the content area'

    'Note: Blocking all popups may prevent important features of some websites from working, such as login windows for banks and shopping websites. For details of how to allow specific websites to use popups while blocking all others, click Help. Even if blocked, websites may use other methods to show popups.'


Privacy-Security-Passwords sub-panel:

'Password Manager'

    'Password Manager stores your login information for password-protected websites, mail servers, and news servers, and enters the information automatically when needed.'

    C-NOT 'Remember passwords'

    BUTTON: 'Manage Stored Passwords'

(NOTE:
It is better to manage your own passwords, offline. If a password database were 'compromised' somehow, you could be in a world of hurt, identity-wise.)


Privacy-Security-Master-Passwords sub-panel:

'Change Master Password'

    'Your master password protects sensitive information such as web passwords and certificates.'

    BUTTON: 'Change Password...'

'Master Password Timeout'

'SeaMonkey will ask for your master password:'

    R-YES 'The first time it is needed'

    R-NOT 'Every time it is needed'

    R-NOT 'If it has not been used for'   LIST: '0'   'minutes or longer'

'Reset Master Password'

    'If you reset your master password, all of your stored web and e-mail passwords, form data, personal certificates, and private keys will be lost.

    BUTTON: 'Reset Password'

(NOTE:
It may be better to manage your passwords off-line, rather than taking a chance you may have your master-password compromised, or you may forget it --- or need to reset it, thus losing the stored data mentioned above.)


Privacy-Security-SSL/TLS sub-panel:

'SSL/TLS Protocol Versions'

    'You can restrict which encryption protocols to use for secure connections. Choose a single version or a contiguous range of versions.'

    'Enable:'   C-YES 'TLS 1.0'   C-YES 'TLS 1.1'   C-YES 'TLS 1.2'

    (NOTE: TLS 1.1 was set ON and grayed out --- i.e. unchangeable.)

'SSL/TLS Warnings'

    'SeaMonkey can alert you to the security status of the web page you are viewing. Set SeaMonkey to show a warning when:'

    C-NOT 'Loading a page that supports encryption'

    C-NOT 'Leaving a page that supports encryption'

    C-NOT 'Sending form data from an unencrypted page to an unencrypted page'

'Mixed Content'

    'Encrypted pages may contain unencrypted content that is vulnerable to eavesdropping or forgery. SeaMonkey can detedt and block it:'

    C-YES 'Warn me when encrypted pages contain insecure content'

    C-NOT 'Do not load insecure content on encrypted pages'

    C-YES 'Warn me when encryped pages contain other types of mixed content'

    C-NOT 'Do not load other types of mixed content on encrypted pages'


Privacy-Security-Certificates sub-panel:

'Client Certificate Selection'

    'Decide how SeaMonkey selects a security certificate to present to websites that require one:'

    R-NOT 'Select Automatically'   R-YES 'Ask Every Time'

'Manage Certificates'

    'Use the Certificate Manager to manage your personal certificates, as well as those of other people and certificate authorities.'

    BUTTON: 'Manage Certificates...'

'Manage Security Devices'

    'Use this button to manage your security devices, such as smart cards.'

    BUTTON: 'Manage Security Devices...'

'OCSP'

    C-YES 'Use the Online Certificate Status Protocol (OCSP) to confirm the current validity of certificates'

    C-NOT 'When an OCSP server connection fails, treat the certificate as invalid'

(NOTE:
The typical home user of web browsing will probably not need to use certificates or security devices. But it is important to set other 'Privacy-and-Security' options appropriately to reduce the likelihood of bad things happening from bad web sites.)

7. Sync panel

(I do not sync SeaMonkey-preferences 'across devices', since syncing would introduce extra processing and network traffic that I prefer to eliminate. I like the settings on other devices, such as cell-phones, as they are --- without the possibility of mucking them up via syncing.)

(This panel simply shows the following message and button --- in the center of the Sync panel.)

'SeaMonkey Sync lets you access your
history, bookmarks, passwords and
open tabs across all your devices.'

BUTTON: 'Set Up SeaMonkey Sync'

8. Advanced panel
(and sub-panels)

'System Integration'

    C-NOT 'Check default application settings on startup'

'Crash Reporter'

    C-NOT 'Submit crash reports'

'Developer Tools'

    C-NOT 'Allow a debugger to connect to SeaMonkey'

    C-NOT 'Allow connections from other computers'

    C-YES 'Prompt for incoming connections'

    'Port number for connection:'   LIST: '6000'

(NOTE:
These settings can incur lots of extra processing and some can open up your identity data and/or your computer to possible attack by 'bad guys'. These are important settings.)


Advanced-Scripts-&-Plugins sub-panel:

'Eable JavaScript for'

    C-YES 'Browser'

    (
    NOTE:

    This is an important checkbutton. It can be used to turn-OFF JavaScript interpretation when you are dealing with a web site that is popping up all sorts of obnoxious ads and/or invoking processing-hungry scripts. 'Bad guys' at 'bad websites' typically use JavaScript to do their 'dirty work'.

    Unfortunately, there is no short-cut button on the main SeaMonkey window by which to quickly turn JavaScript interpretation ON-and-OFF. You need to use the 4-level toolbar path

    Edit > Preferences > Advanced > Scripts & Plugins

    to get to this panel and turn JavaScript OFF or ON.

    There is at least one web browser that has such a shortcut button --- evidence that it is possible and desirable.
    )

      'Allow scripts to:'

      C-NOT 'Move or resize existing windows'

      C-NOT 'Raise or lower windows'

      C-NOT 'Hide the status bar'

CONCLUSION:

These 'SeaMonkey 2.49.2 Preferences Notes' may be used to help me check on SeaMonkey 'Preferences' settings --- for example, for the SeaMonkey release installed in 2020/2021 on an afore-mentioned HP-Windows10 desktop computer.

These 'SeaMonkey Preferences Notes' may be used to help me if/when I have to migrate to a new release of SeaMonkey --- for example, if I have to do another data migration from a Windows 10 computer to a Windows 11 computer --- or when I have to set up SeaMonkey (and its bookmarks) on another Linux computer.

One could bring this web page up in a web browser on any Microsoft Windows or Linux computer, and check SeaMonkey 'Preferences' on that computer by comparing to the notes on this page.

Hence, this web page is provided on the internet --- to help me, and perhaps others.
