Mozilla Thunderbird is an open source client for mail and newsgroups, with features such as support for different mail and news accounts, a junk mail filter, spell checker and a customizable appearance. Version 11 is based on the latest version of Mozilla Gecko, which should lead to better performance, among other things.

Fixed
- Various security fixes
- Various improvements to RSS feed subscription and general feed handling
Developer

Known Issues
- If you are unable to view content for your RSS feeds in the Wide View Layout, you may need to disable the Lightning Calendar add-on if you have it installed or switch to Classic View and restart Thunderbird. (see 531397)
- Running TB 12 with local mail folders and pop3 mail filters may produce summary files that aren’t correctly read by previous versions of Thunderbird. If you decide to go back to a previous version of Thunderbird after running TB 12, you should delete the .msf files for your local folders and pop3 accounts, or repair the folders using the folder properties dialog, to avoid potential data loss.
