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.

Today I agreed to the update of Thunderbird. After the update all my data have been distroyed - no calender data have been shown nor my previouse emails nor my structure of emails worked as ususal. I safed a backup file (zif) from another PC to an external drive. Now it is not possible to import this file because the zip is to big and I get the order to unzip first. If I do this I get a long list of errors and nothing works. Please tell me how to solve the problem! Ralf

Yesterday, I thought I had my original problem with TB fixed by installing v140.5.0. Well, things just got worse.

While trouble shooting it today, it AUTO UPGRADED to v144.0.1.

It appears that any ESR version will auto upgrade to the Release version right after you close the program and shut your machine down. When you go back online, surprise!, you now have 144.0.1 installed with HALF your folders missing.

Good day, After upgrading Thunderbird to 143.0.1, I noticed that a large part of one of my local folders is missing. Searching the internet regarding this problem, I found that this issue happened last year and at other occasions. Why hasn't this problem been solved yet at it is a pain to locate and find the missing data ourself. Any suggestions to avoid this problem in the future

I have automatic updates disabled, for the last month or longer I have refused to update Firefox and kept dismissing the notice when I start up my Firefox. Yesterday when I opened Firefox it just updated itself automatically and without even asking if I want to download the update. I tried to find a way to contact support but all I can find is posting a question on here, so hopefully someone can help me with this question: Why did Firefox ignore my update settings and download and install an update I have been denying for weeks now, and how can I prevent it from happening again?

I am on windows 10

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!

Hi, how do I get rid of

"Error: Platform version '143.0.1' is not compatible with minVersion >=141.0 maxVersion <= 141.0 Maybe try to reinstall Thunderbird?"

It's not very practible to do a new copy everytime a Thunderbird Update has to be made because I mainly store my emails in a local copy (respectively a lot of copies already).

could you please help me?

Thx & BR Eva

Hi, I noticed that my Firefox version has just been force-updated, on two of my computers, even though I had the automated updates unselected. I also noticed that the new version had added an opt-out option to use "AI" for my tabs which I do not want. There may be other settings that have appeared like this forcing "AI" on me and I am not going to check all of them. I will uninstall Firefox as it is no longer respecting my privacy and autonomy as a user, following the full-blown embrace of "genAI" which goes completely opposite Firefox values such as privacy, ethics, environmental responsibility and respect of their users. I might come back when Firefox goes back to being a privacy and environmentally-friendly browser.
