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...

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
