Mail client Thunderbird 68.2.0 is out

A new version of the email client Thunderbird is now available. Thunderbird 68.2.0 was released on October 22, 2019 (the same day that Firefox 70.0 was released).
Thunderbird installations that are on the 68.x version already should receive the update automatically; the development team notes that this is also the case for Thunderbird 60.x installations that have the calendar extension Lightning installed.
Thunderbird 60.x installations without Lightning are not updated automatically to the new version at this point. It is still possible to upgrade but this needs to be done manually by downloading the Thunderbird installer from the official site and executing it on the local system.
Users who upgrade to a 64-bit version of Thunderbird from a 32-bit version should have fewer issues, if any, when they do so. The development team notes that it may still be necessary to pick the right profile as a new blank profile may be created. Affected users may either load Thunderbird with the -p parameter to display the profile selector on start, or open about:profiles from Help > Troubleshooting Information.
Note that Thunderbird 68 does not support all extensions that worked in previous versions of the email client.
Thunderbird 68.2.0 is mostly a bug fix release. It does introduce support for the two WebExtensions APIs Message Display and Message Search but those are the only new additions to the email client.
The APIs were added to newer development versions of Thunderbird but backported to Thunderbird 68.2.0.
- Message Display -- A message can be displayed in either a 3-pane tab, a tab of its own, or in a window of its own
- Message Search -- Gets all messages that have the specified properties, or all messages if no properties are specified.
Improvements include a fix for Thunderbird not maintaining the application window size after a restart, mailing lists editing fixes, and better visual feedback for unread messages when the dark theme of the email client is used.
The team lists two known issues in the new browser version:
- Names of standard folders are not localized when a language pack is used. The team promises that the issue will be fixed in the coming Thunderbird 68.2.1 release.
- LDAP lookup does not work when SSL is enabled. The team suggests to either disable SSL or switch the "Query OSCP responder servers" in the certificate settings to off.


You said that Outlook isn’t your main email client, so which is your main one?
I think its thunderbird
It is Mozilla Thunderbird.
Awesome! This actually solved my problem… what a stupid bug.
If this is the same bug that I’ve encountered, there may be another fix: (1) hover over open Outlook item in Taskbar, cursor up to hover over Outlook window item, and right-click; (2) this should give you Restore / Move / Size / Minimize / Maximize — choose Move or Size; (3) use your cursor keys, going arbitrarily N/S/E/W, to try to move or size the Outlook window back into view. Basically, the app behaves as though it were open in a 0x0 window, or at a location that’s offscreen, and this will frequently work to resize and/or move the window. Don’t forget to close while resized/moved, so that Outlook remembers the size/position for next time.
THANK YOU Claude!!! I could get the main window to launch but could not get any other message window to show on the desktop. You are my hero!!!!
Solved my issue! 6 years later and this is still problem…
Fantastic. Thank you. Size did the trick.
This solved my Outlook problem, too. Thank you. :)

You are a god – thank you!

Yah…thanks Claude. I’ve been having the same problem and tried all the suggestions…your solution was the answer. It had resized itself to a 0/0 box. Cheers

Thanks a lot for the article. Don’t know why it happenend, don’t know how it got fixed, but it was really annoying and now it works :-)
Thanks a lot. I was facing this issue from past 3 week. I tried everything but no resolution. The issue was happening intermittently and mainly when I was changing the display of screen ( as i use 2 monitors). The only option i had was to do system restore. But thanks to you.
I’ve been tried to sole this problem for 12hours. Your comment about changing the display of screen helped me a lot!! Thanks!!
Thank you…don’t know why this happened but your instructions helped me fix it. Running Windows 10 and office pro 2007

I had a similar issue with Outlook 2013 on Windows 10 and this helped me to fix it. Thank you very much!

Thank you again. M
This problem was faced by only one user logging to TS 2008 r2 using outlook 2010.The issue was resolved.
Thanks.
Great tip. Thank you!!!! If it helps, I had to use the Control Key and the arrow keys at the same time to bring my window back into view. Worked like a charm.
Thank you, this worked !!!!
