Hello,

After today's Thunderbird update for Windows 11, over half of the folders in the local folder are no longer displayed. However, the folders are present in the backup folder on an external hard drive.

What's causing this?

Best regards, Steffen Liebig Bautzen, Saxony, Germany

we can not open the web whastapp with my laptop the message from Mozilla Support, we should updated Mozilla latest version. but the problems my laptop still use windows 8 please help and give me the solution How to update? thanks

Dear helpers,

I want to upgrade the hardware of a friend - and so I moved the homedir of the user to the new system, as I have done every time before in my life. But in this special case Thunderbird will not start with the used profile.

Thunderbird generally starts with e.g. the -P switch. But it will not start the default profile of the user. I tried to go this way concerning the versions 115 -> 128 -> 140 without success. I deleted all lock files, if there were any. I spent a lot of time with e.g. copilot - but it could not help me. I'm at a loss.

Is there any documentation with a kind of step-by-step instructions? Can you give me a hint, please?

Here are the details:

Source: linux mint 20.2 uma Thunderbird 115.18.0esr 11th of december 2024

Destination: linux mint 22.3 zena Thunderbird 140.7.0esr

Thank you in advance for your help.

Many months ago I reported this error/bug but it remains unresolved, even though it was supposedly progressed to Mozilla.

I have a desktop PC & a laptop. The problem only occurs on the laptop. I am running T/bird on ESR channel on both machines.

On the laptop, even though the settings are not to update automatically it does, reverting to the release channel. This displays the following bug!

Instead of a "Junk" and a "Spam" fold I get 2 "Spam" folders, but a closer look shows the paths as being correct, what you would expect. The folder will not rename.

Reinstalling the ESR version restores the correct folder names - UNTIL THE NEXT TIME THE PROGRAM AUTO-UPDATES when it shouldn't!

I'm just trying to update my version of Mozilla on my phone but can't seem to figure out how to do it. It's always been a nothing operation but somehow got tricky.

When I launch Thunderbird after downloading an update I get a message that says 'the installation seems to be incomplete. Check your hardware (what hardware?) and disk set up and/or reinstall. How do I check hardware and disk? If i reinstall will I lose my old messages?

I wish thunderbird/firefox would stop behaving as if everyone knows how to repair these things. I still haven't managed to stop thunderbird from asking for and often rejecting my email password, despite two kind people trying to sort it out.
