Thunderbird Running Slowly (pop). Helped by accessibility.force_disabled=1. (win10)
Hi,
Starting less than a week ago Thunderbird has been running slowly. Sometimes it's quite noticeable and sometime not so much. E.g. clicking on a different folder sometimes happens immediately and sometimes takes maybe 4 sec. to display the folder. Clicking on a message sometimes displays it immediately but can take 7 or 8 secs. to display. Receiving messages seems normal and I haven't noticed slower speeds sending. Clicking on Reply for a message can take several seconds, and dragging a message to a different folder can do the same. Once I'm editing a message the edit speed is normal with no slow down and the address book and editing filters are both fast. I didn't make any changes to Thunderbird, this just started happening on it's own.
I'm running Thunderbird ver. 128.4esr (32-bit) on a windows 10 desktop PC using POP to access messages. I ran Compact on all the folders to no benefit. I don't know what else to try.
Please let me know how to correct this or figure out what's going on.
Thanks, Mike

At https://www.reddit.com/r/Thunderbird/comments/1grt0xl/thunderbird_laggs_since_few_days_12843esr_64bit/ I found this suggestion: Scroll all the way down and click the 'Config editor' button on the right, click 'Accept the risk and continue', search for accessibility.force_disabled, change the value to 1 (was 0), click the check mark after making the change, restart TB.
It worked.

Please update to 128.4.3. If you still see the problem...
- Start Windows in safe mode with networking enabled https://support.microsoft.com/en-us/help/12376/windows-10-start-your-pc-in-safe-mode
- Still in Windows safe mode, start Thunderbird in Troubleshoot mode https://support.mozilla.org/en-US/kb/troubleshoot-mode-thunderbird
Does the problem change?

Great.
Now that we know that helped performance, please try accessibility.cache.enabled=true (you may need to add the setting) with accessibility.force_disabled=0
