Delayed response to mouse movements and clicks (Macbook)
Thunderbird 140.7.0esr (aarch64) on macOS26.02
For several days now, Thunderbird has been responding extremely slowly to mouse movements or clicks. This leads to undesirable results because emails are suddenly deleted that should not be deleted (due to forced double clicks). Or folders are not opened, or the wrong folders are opened.
The last change was updating Thunderbird. Is this a known bug?

Seems the switch between the modes have eliminated the issue.
Did not exclude addons when in troubleshoot mode, so only difference was the defined symbols in header line. During troubleshoot mode issue did not exist. And when back to normal mode anything “works as designed”. Means for the time being the issue is gone.
Thanks!
Just running Thunderbird in troublshooting mode would not have fixed a problem. See here for what to do if a problem does not occur in troubleshooting mode:
