    "SeaMonkey 2.26.1"

    June 21, 2014

    Version: SeaMonkey 2.26.1


    This is a fairly easy to use browser. I downloaded it to use it with the AARP web site since Firefox and Safari no longer do. SeaMonkey will be my backup browser instead of Opera. SeaMonkey is similar enough to Firefox that I could make it my go to browser.


    Some of the SeaMonkey preferences/settings are not easy to find. Even though it's from Mozilla, the preferences menu is not the same as Firefox's preferences menu.


    SeaMonkey is a decent browser for most users whether they prefer links to open in tabs or to open in separate windows. It really is flexible in that respect.

    Full Specifications

    What's new in version 2.1rc1
    • Sync (f.k.a. Weave) is now included directly in SeaMonkey. Sync allows you to keep your browsing history, passwords, bookmarks, preferences and tabs in sync across different devices (computers) in a secure way.
    • SeaMonkey windows can now be themed with Personas (lightweight themes).
    • The bookmarks system has been reworked to use the Places framework shared with Firefox (already used for history data in SeaMonkey 2.0), including a new Bookmark Manager and fast bookmarking button in the location bar.
    • Find in Page now works with a toolbar instead of a modal window.
    • OpenSearch plugins are now supported and the default for web search.
    • An optional search bar (including suggestions if the search engine supports it) is available in browser toolbar customization, and an engine manager for OpenSearch is available.
    • More toolbar widgets are now customizable.
    • The new Add-ons Manager opens directly in the browser now and has received a major facelift.
    • The new Data Manager now unifies cookie, permission, password, and form data management.
    • Plugin crashes do not take down the whole application anymore since plugins run in their own processes now.
    • Plugins now work in feeds shown in MailNews windows.
    • The feed preview UI and the Helper Applications preferences can now detect the system's default feed reader and use it.
    • Page zoom is being remembered on a site-specific basis now.
    • The browser tab bar is now scrollable to cope with tab overflow. This includes an "All Tabs" navigation button to quickly list all open tabs.
    • You can now drag and drop downloads, e.g. from the Download Manager to the desktop.
    • SeaMonkey now shows "doorhangers" for notifications like remembering log-in passwords or after installing an extension.
    • The new DoNotTrack HTTP header is supported (configurable in Preferences).
    • A page with Troubleshooting Information (about:support) and the option to restart in Safe Mode are now available from the Help menu.
    • Loading the URL about:memory now shows how much memory is used by different parts of SeaMonkey.
    • SeaMonkey should now support more websites that previously appeared to only work with Firefox (configurable in Preferences).
    • Built-in extensions (ChatZilla, JavaScript Debugger and DOM Inspector) are now installed into the profile.
    • News messages can now be deleted from local storage.
    • Cascaded Session Restore improves restoring large browsing sessions.
    • SeaMonkey now uses Omnijar which results in fewer installed files, less fragmentation and better startup time.
