Download SeaMonkey 2.39

Mozilla has released version 2.39 of SeaMonkey. SeaMonkey is the continuation of the former Mozilla Application Suite and consists of a web browser and programs for e-mailing and reading news. A simple HTML editor is also provided. Unlike the Mozilla Application Suite, SeaMonkey is maintained by the community, while the SeaMonkey Council oversees maintenance. The release notes for this release are as follows:

Sea Monkey Release:

• The SeaMonkey project is proud to present SeaMonkey 2.39: The new major release of the all-in-one Internet suite is available for download now! Building on the same Mozilla platform as the newest Firefox release, it delivers the latest developments in web technologies such as HTML5, hardware acceleration and improved JavaScript speed.
• SeaMonkey 2.39 is available in 26 languages, for Windows, Mac OS X and Linux.

Known Issues

• The SSL 3.0 encryption protocol is no longer supported due to security concerns (bug 1106470). Legacy websites may still rely on it and will not work with the newer TLS 1.x protocols. Contact the website administrator to update their server to resolve the issue at the source.
• Lightning does not work with SeaMonkey when icaljs is enabled, which it is by default (bug 1081534). As a workaround, disable icaljs by setting the calendar.icaljs pref to false in about:config.
• The Remember Passwords add-on breaks password handling. Please disable or uninstall this add-on using the Add-ons Manager.
• You cannot set up a new Sync account or pair a device anymore (bug 998807). Workaround: Use an older version of SeaMonkey for such tasks for now.
• Data loss warning: If you use a profile with this or any later version and then try to go back to SeaMonkey 2.0, SeaMonkey will rename your history file to places.sqlite.corrupt and create a new places.sqlite file, effectively resetting your browsing history. This is because the internal format changed and the upgrade process only works in one direction. Additionally, running MailNews with local folders and POP3 mail filters may produce summary files that are not correctly read by previous versions of SeaMonkey. If you decide to go back to a previous version of SeaMonkey, you should delete the .msf files for your local folders and POP3 accounts or repair the folders using the folder properties dialog in order to avoid potential data loss.
• After creating a news account through clicking a news URL, the MailNews account wizard may be broken (the account type will always be News). To work around the problem, set the mail.server.serverX.valid pref (where X is the internal number of the corresponding news account) to true in about:config, or delete the invalid news account (bug 521861).
• Web pages may appear differently in the MailNews feed reader than in the browser (bug 662907). Workaround: Add a “noscript {display:none}” rule to your userContent.css (note that the Stylish add-on cannot be used here since it does not integrate with the MailNews feed reader).
• Select Element by Click doesn’t flash the element in DOM Inspector on Windows if hardware acceleration is enabled (bug 594299).
• The option “When opening a bookmark group” / “Replace existing tabs” under Preferences / Tabbed Browsing does not have an effect anymore (bug 664101).
• Lightning keyboard shortcuts for accessing the calendar tab from within the MailNews window or from the main menu (Ctrl+Shift+C/D) do not work. (bug 514512).
• If you try to start SeaMonkey using a locked profile, it will crash (see bug 573369).
• Some synaptic touch pads are unable to vertical scroll (see bug 622410).
• Under certain conditions, scrolling and text input may be jerky (see bug 711900).
• Mac OS X and Windows: Citrix Receiver no longer works. As a workaround, mark the plugin as Always Enable in the Add-ons Manager (see bug 1025627).
• Windows:
  • Norton/Symantec anti-virus scanners may report that some parts of SeaMonkey (eg the file freebl3.dll) are suspicious. If you downloaded SeaMonkey from one of the official download sites, this is a false alarm. You might experience problems with secure websites when this happens. To fix the issue, instruct your anti-virus software to ignore these files (and move them out of quarantine) and/or switch to another anti-virus software and reinstall SeaMonkey.
• Linux:
  • The cursor may change to “drag & drop” mode in the mail window, causing a hang (bug 736811).
• Mac:
  • When hardware acceleration is off, background colors in the UI (toolbar, status bar etc.) might not update correctly when you switch focus from/to a window. Users running Macs with certain older hardware (eg Intel GMA 950) will experience this even if they haven’t turned off hardware acceleration in Preferences (Appearance/Content) (bug 626096).
