Forum zhromadźenstwa Thunderbird

I was using Thunderbird this morning 08-02-2024 and for some reason a quick pop up window appeared. I now get an error messasge "cannot load xpcom" I uninstalled Thunderbird and tried to download/re-install but cannot get past the donation part which I have already donated. Does this mean each time I have to re-install I have to now make another donation? I noticed that I have a Firefox installer but no Thunderbird installer. Was it removed when I did a uninstall?

Does anyone know how do I can get my feeds back? I hope all my saved feeds are still stored somewhere as I use them for research. I just went to look something up and the whole heading is totally gone!

Ever since updated to TB Nebula (128.1.1esr (64-bit)), downloading of email has become super slow. Each mail takes more than 10 seconds. Many times, there are 100+ emails and it is not responding till all emails are downloaded. Need help.

I understand that Postbox, based on Thunderbird, will never be updated to become compatible with Apple silicon chips. Therefore Postbox will cease to work when Rosetta will be deprecated on macs. Consequently my question is where can I find directions to import messages, filters, and preferences from Postbox to Thunderbird?

I am using Thunderbird on Windows 11 and I have foolishly allowed it to update itself to release 128.1.0.esr without checking the bug reports first. Now it turns out that this release removed the possibility to search the calendar for past events, which is absolutely essential for me. There is a Bugzilla entry for this but it is bogged down in discussions about who needs which date ranges to search in and how many instances to show for recurring events, so I don't expect a solution any time soon. How can I revert Thunderbird to the last release which still has that functionality? I have regular backups of my userprofile folder in case it helps.
