I get an error message when I try to update (see screen shot below). Thunderbird is on a Windows 11 Pro PC with the latest Windows updates. This has been happening for a couple of weeks now.

Thanks in advance for your assistance.

Signed on to Thunderbird a couple of days ago to see a message about a new release. Seeing no way around it, I went for the update. Thunderbird now opens to a screen asking for an account setup. Name, email, and password--which I assume is the main email server (AOL in this case). I fill this in, click on test, and Thunderbird comes back with an available POP3 configuration it found, which is not the one I have been using for several years. I try it out, Thunderbird tests the password and finds something in the password or configuration that doesn't work. I try a manual configuration the the correct pop3 and smtp addresses and get the same result. I am at a complete loss at this time. This is all I get when I try to open Thunderbird--none of the usual email boxes, calendar, contact screens at all. I cancel the setup and get an option to continue and potentially not have access to some features, or exit. I click on exit and a new screen opens with file tabs for email, calendar, address book, and tasks. Looks nice, but there is no data brought forward on any of these tabs, and email looks like it has not been set up (no surprise--no inbox or preview box).

Any ideas on how to complete his setup and bring the data in, or on how to go back to the previous release and uninstall the new version?

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.

I haven't updated Thunderbird since version 52.9.1 because of the interfaces which are painful for me and I don't see much. it still works well but does not support encrypted emails. I would like to install a recent version of TB but how can I make it look like the older, much more configurable versions? Please tell me if this is even possible.

Hi,

Since your latest update I have to daily sign in into all my accounts again. Why? How can this be fixed?

Further how to deactivate updates as issues like this are too often.

Thank you< Tobias

How can you remove the regular reminder to update firefox to the newest version on macos that occurs when you tick "Check for updates but let you choose to install them"?

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

I've been struggling for months to standardize a deployment of Firefox ESR across various client environments that reliably auto-updates and doesn't cause UAC prompts and XULRunner profile error pop-ups(I work in IT).

We deploy Firefox ESR in bulk on machines via a batch script which runs as SYSTEM, with msiexec /i and /qn flags.

Firefox installs fine, but then users are typically met with a UAC prompt when they first try to run Firefox. If they decline, then the UAC prompt comes back again next time and often fails to update at all, so the machine is left on an older, vulnerable version.

Regarding the environment: we have deployed the Firefox ESR admx templates and enabled the relevant auto update settings in Group Policy. But only some machines seem to stay up to date, and it seems like this only happens if a user with local administrative privileges has run the program at least once.

What I find unusual is that Firefox seems to attempt to make a "Background Updater" scheduled task for every user that runs the software on each PC, but these users do not have administrative privileges, and the scheduled task is set to only run when that user is logged in. Obviously a scheduled task running as a user with limited privileges isn't going to be able to update files in the Mozilla/Firefox subdirectory in "Program Files" as by default that's read-only access for non-admin users. And, obviously, if a user with local admin privileges DOES log into the machine, then it can update once, but then the scheduled task that it creates for that user (now with admin privileges) will only run when that user logs in - and we don't login as "admin"-privileged users day-to-day.

So, various machines are out of date, running vulnerable Firefox 128 instead of 140 or 142 even though they're all deployed from the same image and have the same policies and restrictions, and ran the same installer for Firefox.

Is there some reason why the auto update scheduled task isn't created at installation time, when administrative privileges have been granted? It's very odd that it doesn't, because then every time a user logs into a machine it seems like Firefox ESR creates the background upgrade task under a non-admin user which simply won't work. I see machines having 4 or 5 background upgrade scheduled tasks, all created by Firefox ESR, and yet the software still won't update - there's a UAC prompt every time the program launches, and going to Help -> About shows "Restart Firefox to update..." but then when clicking the button to restart Firefox, we get the UAC prompt, user doesn't have privileges, so this goes around and around in circles.

Is there a reliable way to keep Firefox up to date without manually logging into each machine and going through the UAC prompts? Can we manually create a scheduled task with the correct user account that has privileges to actually upgrade Firefox?

The background auto update mechanism simply doesn't make sense to our team on a machine-wide install.

Hi,

I installed Thunderbird 140.2.1 on WIndows 11 v25H2 with winget but it autoupdated to release version 144. I uninstalled release version 144, re-installed esr version and disabled Updates in Settings, but it auto-updated to release version. So I uninstalled one more time release version, installed esr 144, disabled Updates in Settings and I set up the registry key DisableAppUpdate at 1 but Thunderbird auto-updated again to release version 144.0

Please, can you tell me what can I do to prevent Thunderbird esr auto-updating to release version ?

Thanks.
