Thunderbird Tekoha Aty

Since I upgraded to macOS 26 I noticed an annoying issue. When closing Thunderbird window and going back to another application the focus is being kept by Thunderbird for a few second making it impossible to click on the other app.

Steps to reproduce:

• open Thunderbird
• close Thunderbird window (using Cmd+Q or clicking the red button on the top left corner)
• click on any element of the Desktop

Expected:

• the element is selected

Result:

• nothing happen

After a few seconds (from 1 to 3), the macOS menu change from Thunderbird to Finder and then everything works properly.

Any help would be much appreciated.

Hello:

My Windows Thunderbird has become unresponsive, taking forever to connect to my various accounts. I suspect the problem is with my GMail account--which is not my primary account--is causing the problem, but I am unable to un-sync GMail's All Mail folder.

I was able to get into troubleshooting mode, but TB was still unresponsive.

I have copied the profile in question to my Linux machine, with TB V140.4.0esr, to try to repair the profile, but the problem is recurring there as well.

Is there a way to manually edit the profile file(s) to remove the GMail account from Thunderbird?

Any insights would be much appreciated.

Thanks

Hello,

I'm using Thunderbird in Debian GNU/Linux 13 (trixie).

Version: Mozilla Thunderbird 140.4.0esr

apt package: thunderbird/stable-security,now 1:140.4.0esr-1~deb13u1 amd64 [installed]

The last few weeks I started getting the problem that Thunderbird freezes, it stops responding and Debian (with the default gnome UI) shows a popup window saying "Thunderbird is not responding", then I wait for about 10 or 20 seconds, and then Thunderbird becomes responsive again.

Apparently Thunderbird is doing something that takes a long time (perhaps going through messages to index them for quicker search or something like that, I don't know), something that should be done in a background thread so that the program can remain responsive, but for some reason that heavy work is done by the main UI thread causing Thunderbird to become unresponsive.

This problem has gotten worse over the past few weeks, so I really want to do something about it before Thunderbird becomes completely useless. (At the moment I can still use Thunderbird for like 10 minutes in between the freezing, so it's not yet critical.)

How can I find out what Thunderbird is doing while the "Thunderbird is not responding" is shown?

For example, is it possible to configure some logging or performance profiling that would output to a file some information about where the program spends its time?

Other ideas about how to troubleshoot this?
