Since to old add-on enabling customization of the message header toolbar doesn't work now, where might get one the is compatible with Thunderbird?

Thanks, James

In certain instances, I can no longer copy/cut from Cardbook notes. This happened in last few months. I just have time now to post the problem. I know since then Thunderbird had updates and so had windows. I am on Thunderbird 128.5.2esr and Windows 11 and firefox 133.0.3 I used to be able to select a word or many words and then right click. Then copy or paste would show up as option in a list. Now no list shows up. But control c and control v sometimes works. If I control c and control v within the note that works. I can copy from something like Word and control c and paste using control v and vice versa. But if try control c in notes and then control v in website that does not work. And that is what I use most.

During recent update 148.0 (64-bit) google calendars are not shown either in "Events and Tasks/Calendar" or in "Today's Pane".

Subscribed calendars are still there, but nothing is shown in the days/weeks/months entries apart from the first calendar in the subscription list! Nothing else. And nothing in today's pane.

Reinstalled Thunderbird and reinstalled "Provider for google calendar" but nothing changed.

Thanks, GG

Hello,

I'm having a problem moving messages from one folder to another. There's one message which will not move no matter what I do. I'd like to turn off QuickFolders so that I can determine whether it causes the problem. How do I turn QuickFolders off, and then when I'm done with my experiment, turn it back on again?

I am trying to install an add-on to enable the transfer of large email attachments but, having tried to install a "selected" Filelink add-on, I receive a message that it cannot be installed as it is not validated by Mozilla. Please advise which add-on is accepted. Thank you.

I'm running Thunderbird 157 64bit for Google email, Calendar & Tasks. This has worked nicely for months even after the upgrade to 157. Today Calendar & Tasks fail to connect and are completely blank. Apparently the Add-on 128.5.12 (Philipp Kewisch) that made this work has been disabled for some reason. Please don't tell me that Thunderbird has suddenly decided Google Calendar and Tasks just aren't needed by anyone anymore. There is no new connector available that I can find, just a suggestion to go back to an older version of Thunderbird? Please help me understand. Thanks!

With Thunderbird 155 our Shortcuts deletion plugin doesn't work anymore.

Now all the worst shortcuts like "a" are back. 

(I never understood why it isn't something like "Alt+A" )

We need to deactivate all the *(/&%$&% shortcuts. We deactivated them via a plugin. But the plugin does't work with 155. Does someone knew what mozilla chaged with the shortcuts handling, so we can change our plugin acordingly?

Just updated to Thunderbird 157 and all my calendars are now disabled because the google calendar add-on is not compatible and was disabled. How do I enable my other calendars or move back to 156 while I wait for an update for the google calendar add-on?

Ihave installed and configured Google-4-TBSync addon to synchronise contacts between Google and Thunderbird and all works fine.

Just got an email from Google entitled "[Action Required] Mark AI agent OAuth clients as agentic for Google Workspace MCP by Nov 11, 2026"

Does anyone know if that is sometyhing I need to do for the addon to carry on working?

Thanks

I really hope somebody can help me with the "Google-4-TbSync is incompatible with Thunderbird 153.3.1" Are there any solution to this, because the developer seems to have stopped the development of an update of this extention. I desperately need to sync my Google contacts with my Thunderbir contacts. Any help will be welcomed.
