Thunderbird 68.7.0 has been released

The developers of the email client Thunderbird have released Thunderbird 68.7.0 to the public. The update for the stable 68.x branch of the email client is a maintenance update for the most part that resolves more than a dozen issues in the email client and improves MailExtensions support in the client. Additionally, it fixes security issues.
Thunderbird installations that are already on Thunderbird 68.x will be upgraded to the new version automatically. Users may run a manual check for updates to get the update asap may select Help > About Thunderbird to get it downloaded and installed at that point.
Thunderbird installations that are still on previous main versions won't be upgraded to Thunderbird 68.x automatically unless Lightning is installed.
Thunderbird 68.7.0
The team continues to enhance MailExtensions support in the Thunderbird email clients. Thunderbird, which is based on Firefox, is undergoing the same architectural changes as the Firefox browser. The move has implications on extensions support and one of the main changes is that the next major version of Thunderbird, Thunderbird 74, will only support MailExtensions (similarly to WebExtensions in Firefox).
MailExtensions are based on WebExtension technology but designed specifically for email scenarios. Thunderbird supports some WebExtensions APIs on top of that but core functionality for add-on developers is provided by MailExtensions APIs.
In Thunderbird 68.7.0, MailExtensions now support RAW message source and to make messages as junk/not junk.
The maintenance release fixes the following issues in the email client besides that:
- Exchange server account setup improvements.
- Fixed threads collapsing when opening news messages in a new window.
- Fixed add-ons not being updated automatically to new (compatible) versions after the upgrade from Thunderbird 60.x.
- Made the extra recipients panel keyboard accessible.
- Fixed status bar not being detectable by screen readers.
- Fixed a WebExtensions permissions issue when querying by folder name.
- Two Calendar fixes: cancelled events did not show with a strike-through and invitations with embedded null bytes did not always decoded correctly.
The two security issues fixed in Firefox appear to be the same issues that Mozilla fixed in the Firefox 75.0 web browser release.

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. :)

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. 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!!

This problem was faced by only one user logging to TS 2008 r2 using outlook 2010.The issue was resolved.

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.
