I updated to 155.0.1 via the update modal yesterday, on MacOS Tahoe, and it didn't restart as normal. The main message pane was blank with "No Message Found" (screenshot attached).

I tried installing a fresh 155.0 over, that did not work; but, a restore of the prior app from my Time Machine did work -- that is, the application not the user profile data.

I just thought this was strange; never ran into it.

If there is an issue and I can help test it usefully, I happy to do so (I have backups! LOL).

When I started up Windows 11 on my new laptop, I had to connect to the web via Edge to be able to install Firefox. I foolishly went on to install Firefox via Microsoft Store. I have now installed Firefox from the Mozilla website via the Microsoft Store version, but I cannot uninstall the Microsoft Store version. I don't have access to the folder where it is installed even though I log on as an administrator.

Frustrated that told to do this do that, and more of stuff I don't understand. Change this, Change what. No matter what how many times i change this or that nothing helps. i have a big headache, and it isn't right to put so much stupid crap that I dpn't understand at all. Nothing is simple; it's not simple. I already paid a $20.00 for a donation so I can use Thunderbird. I can't even use the freaken Thunderbird. I can't figure out what the heck who ever expects me to do this, do that, than more of the same. All I want, is to be able to use Thunderbird, transfer all my emails to Thunderbird. Use the Thunderbird without alot of crazy ass questions, that I have no answers. If this is diffcult to read imagine how I feel. It should be so difficult to use anything, but it sure is. Even writing this, what do I gain, nothing, go away, lose the money I donated for Thunderbird. I would really really appreciate any help to help me sit up this thunderbird email. I really would. Help, dispirited what can I saw. Once this note or what ever is send. It my all be in vein. Tom You can't email, because Firefox screwed that up. I don't have a freaking email right now. can be text on phone to figure out what to do my number [edited phone# from public community support forum]
