Thunderbird is locking up and lagging

Hello,

On my new laptop, Thunderbird is locking up and lagging over and over. It happens to everything I try to do when I start the program, and then after I use the program for awhile, everything is OK until I get an incoming email - then Thunderbird locks up until the email is fully loaded.

When I first load the program lags are happening when I: Select a menu, choose an email to view, when I try to type something the cursor freezes and then after a short wait it types what I just typed. Pretty much all operations lag a lot, even clicking on the X to close the window. After I use the program for awhile, this gets better, but not 100%. As I mentioned the program lags when I get an incoming email.

I only have one add-on installed and it's disabled. It's called, "Manually Sort Folders." I have the latest version of Thunderbird. I'm running Windows 11 64 bit. My laptop has Optane memory built in. Is the Optane technology causing this? When I run Firefox I have no issues at all - even if Thunderbird does.

As you can imagine this is frustrating when I get to work and I have to answer a lot of emails. Would you guys walk me through possible solutions?

Thanks, Michael

Hello, Thunderbird has become so laggy that I can barely use it. I tried a couple of fixes, but no luck. Not having trouble with Thunderbird on my Windows 10 desktop, just my Windows 11 laptop. The above suggestion was way to technical for me. Would anyone have any suggestions/help? Thanks! Michael

Hello, I uninstalled Thunderbird and reinstalled. I also removed the only add-on. When I have a bit more time I will try troubleshoot mode and get back to you. It's so odd. I am experiencing zero issues on my laptop with everything but Thunderbird. Thanks.

Hello Again,

I've fixed the problem. I think it was due to an error with an add on. The solution was to completely remove Thunderbird from my computer. I used the info found here:

https://www.techwalla.com/articles/how-to-uninstall-thunderbird-completely-and-then-reinstall-it

Once I got TB fully out, I downloaded and installed the most recent version of TB and that solved my problem.

Thanks.

Hi, Friendly message about above solution. Make sure you backup your address book and make note of your server settings before you attempt to fully wipe Thunderbird from your computer!

- Cheers.
