I've never knowingly installed a non-mainline thunderbird, but earlier this week I started getting the following when I open Thunderbird:

This is an unsupported version of Thunderbird!! Thunderbird monthly releases are not considered stable for general use. Use at your own risk, this build is the same quality as Thunderbird Beta.

Checking the version of thunderbird.exe It says its v131, which happens to be the same as the copy of Firefox installed. When I remove and reinstall Thunderbird it starts off as 128 but quickly changes to 131, even after uninstalling Firefox. (Also annoyingly, this stomps on the version in the profile, which 128 claims is no longer compatible, because Thunderbird isn't clever enough to save a copy of files when it makes "breaking" changes to user files)

I wouldn't being on 131 if actually worked, but it gets stuck in the handshake with my IMAP server, and doesn't even show the local folder caches. (It also for some reason shows the window controls on left side of the window title bar, rather than the right).

How can I restore standard functionality?

In Windows 11, the Address Book is accessed via an icon on top left of the TB main page or Alt+2. In Windows 11 is there a similar key combination to view the folders below Local Folders?

Dear Thunderbird team I am an avid user of TB (home desktop Windows PCs), but I have been resting on my laurels on v78 for a few years now. I know, shame on me. I would like to upgrade to a stable "modern" release (emphasis on "stable" please). Can you please advise if I should aspire to end up on 115 or 128, and how I might get there ? From reading some older blogs, there is advice that says.... first go to v91, then v102, then v115, and so. That seems a bit tortuous, but I am happy to do so if that is still the recommended approach.

Also, can you advise on how I manage my Profile through all this, do I need to do various exports/imports as I move through these different versions, etc.

Many Thanks

Since yesterday I have Thunderbird nebula 128.2.3esr on my Windows 10. But I cannot find my calendar and the new left sidebar isn't available, but only a little button on the left upper corner with seven button without function. I've tried a lot, I cannot find any description about a same failure in the Internet.

I'm running for quite a time Thunderbird on Windows up to Win11 without any problem. For about 3 years I'm using the same TB profile in dual boot environment with Linux Mint (v21 until last week and now version 22). I understood why I didn't get access from Linux side after the latest TB update in Windows as obviously the file structure and other things had changed to make it incompatible to elder versions.

However, as Linux is now my normal working environment, I've tried it again after upgraded my system to Linux Mint 22 Cinnamon 6.2.9 , kernel 6.8.0-44-generic and failed again, having the same error message when starting the profile: "Thunderbird is already running, but not responding. To use Thunderbird, you must first close the existing process, restart your device, ore use a different profile. "sudo killall Thunderbird" didn't find a running process.

I've tried importing everything in a new profile, which worked (more or less), but failed with all attempts getting access to my local profile. A local profile appears after importing but contains no data, trying to import its data separately doesn't trigger any error message when just ticking "E-Mail", but nothing is imported. When ticking "E-Mail" and "Settings", I'm getting a red alert that asks me to look into the error console which doesn't help either.

What can I do ????

I have been using Thunderbird Portable on a laptop for many years. I not longer need the portable feature and I understand that it is slower than the regular Thunderbird. How can I switch to Thunderbird? And I need the method most suitable for 80-year-olds who aren't that computer savvy, please.

I have Thunderbird v. 102.15.1 installed. I do not want to update to v. 115.16.2. I have set HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Mozilla\Thunderbird\DisableAppUpdate = 1. This worked for several months. However yesterday when I turned my computer on, I found that Thunderbird had updated to v. 115.16.2. After a great deal of fruitless attempts to downdate it again, I finally restored all of my C: drive from a backup I'd fortunately made just the day before. That worked and brought back v. 102.

However when I turned my computer on this morning, I found that once again Thunderbird had updated to v. 115. When I go to Menu > Help > About Thunderbird, it shows a window saying "Updates disabled by your system administrator". Yet "disabled" or not, Thunderbird updates itself! (I don't know what "system administrator" means - it's my computer and I'm the "administrator".)

How can I keep Thunderbird from updating without my permission?

I use google search engine. Google is blocking my email account and wants personal identifying info to unblock. One solution recommended is to have my mail data transferred elsewhere. I want to use Thunderbird for my mail. On Thunderbird's download page for Windows 7, an error 404 comes up. Where is the download page? Thanks.

Hello,

So I have Thunderbird which came with my Mint 22 install. My issue is that I imported my contacts (cvs) from Outlook into my personal contact folder. However, when I try to compose an email it can't seem to find the person I'm looking to message. I set my personal folder as default but it still won't work. I love Thunderbird but if it's going to be a problem sending emails then it's useless to me. Can someone please help me with this.

Kind Regards,

Bruce

The version 131.0.1 on this page - https://product-details.mozilla.org/1.0/thunderbird.json

Lists it's category as "Stability" when the release notes page say it's for testing here - https://www.thunderbird.net/en-US/thunderbird/131.0.1/releasenotes/

Hopefully something can be adjusted or fixed as I don't believe the 131.0.1 should be in the "Stability" category on the first link/json data.

While setting up the account on Windows 11 and trying to connect with Gmail for credentials, the pop up window is hanging blank without connecting or populating any data. Any help?

My Maingear laptop bluescreens, I can boot via USB stick and have been able to copy off the files from c:\Users\(account name)\AppData\Roaming\Thunderbird.

I purchased a new Microsoft Surface Pro and installed Thunderbird, but I can not find this same data folder. I can make the troubleshooting information from the Surface Pro if that would be helpful.

I am trying to get TB (102.10.1) to use my system colors for

1. navigation-toolbox-background {background: AccentColor !important;}

I've used AccentColor in Firefox for...

1. TabsToolbar, #navigator-toolbox, #tabs-newtab-button, #titlebar toolbarbutton:not(:hover):not(:active), #scrollbutton-up:not(:hover):not(:active), #scrollbutton-down:not(:hover):not(:active), .titlebar-color {

   background: AccentColor !important;
   color: AccentColorText;
   fill: AccentColorText !important;

}

...but I'm doing something wrong in TB. Please let me know the proper usage for TB. Thank you for taking a look at this.

Yesterday morning I opened my email only to discover that TB had been automatically updated to 115. I did not update it, and I do NOT want 115, it's miserable! How can I safely uninstall 115? TB info shows I'm "currently on the esr channel." what is that and what does it mean? Is the new 128 less awkward? that is, would it be safer to update to 128 than to uninstall 115? Thanks for advice and guidance, Gail

Just today after installing latest Microsoft Windows 10 64-bit and upgrading Thunderbird to 128.2, when I launch Thunderbird, after 30 to 60 seconds, the app goes "busy" with the hourglass pointer, and I have to kill and restart. Each time it still freezes after one mouse click. It has been working on this computer for months without problems until now. The only thing that changed was an update to the latest Microsoft preview WIndows 10 64bit from "Windows Update" a couple days ago.

Is this my system only, or are others having this freeze problem? I have to kill Thunderbird after waiting several minutes with it still frozen.

I don't want to change to another email program.
