I am on release 140.12.1 esr and there appears to be no new updates available. If so, what release should I be on and can I just download and install to get back on the latest release

I recently changed onto the new release channel by installing version 136. I now find that this new release channel appears to have installed version 138, but it is reported as a beta version. I do not want to use beta versions, as I am having a lot of problems with it, so how can I return to a stable release?

While attempting to upgrade my Ubuntu Thunderbird client, I saw the attached screen. I'm concerned because of the unsophisticated style of the page, and the fact that it asks for my password, which makes me think "phishing". Can some trustworthy person confirm that this is a legitimate screen?

Good day, thank you in advance for your help.

I have two questions: 1. Which Thunderbird version is better than ESR? Could you share your opinion?

It's faster and it applies all changes more quickly, that's how it seems right now.

If there are still 32-bit and 64-bit versions available simultaneously, I'll test it sometime. I have no idea what kind of channel that would be.

Problem question:

In Thunderbird 64-bit POP3, the font changes to blue for every second email, including in replies. Can you tell me how to display every email in black? Only the second email in the inbox is displayed in blue, so the text isn't blue when receiving emails. When composing, everything looks black. What do I need to change?

Question 2: Regardless of whether it's 32-bit, 64-bit, or any channel, I see updates to the latest version, and in the program itself, there's an option to view older updates, but everything is white. I only see white and nothing else. Is this intentional? I can't see the update, but it's still current?

``` Thanks for the information

My windows 10 PCs are running ver 140 (and say they are running the latest ver and no updates are available, but my W11 Pc is running v144. When I try and copy profile from 140 to 144 about 1/3rd of the directories are missing. I usually do to this prior to going on a trip when I copy from desktop pc running W10 to laptop with W11. Last time I did this there were no problems as both were running v140, but now that the laptop upgraded itself to ver144 that's no longer possible as a third of the directories end up missing - things like Inbox, Trash, Drafts, Archive etc which are fairly important. I've paused all Thunderbird updates until the problem is resolved. Can you help please?

Apparently Windows 11 won't upgrade from v23H2 to 24H2 because the very nice cpu (and system) don't support SSE4.2 or PopCnt instructions. While v23H2 won't get updates after November of 2025, I tend to use operating systems WAY beyond no more updates without problems, and only upgrade when browsers no longer update and support some websites, notably banking and credit card sites, for example.

Any way to get at least a rough idea of when/how long Firefox will continue to update on Windows 11 23H2 so I can plan ahead? Usually it's a year or 2 or more after Microsoft stops updating the OS.

Thanks.

I have Thunderbird installed on a Surface Pro running Windows10 and on a Surface Pro running Linux Fedora. When I use the Windows10 computer to prepare a Thunderbird export file for the profile, the Fedora machine Thuderbird import command will not read it.

The Windows10 machine has Thunderbird 147 and the Fedora machine has 146. Is the difference in version responsible for the failure to import the profile files? Or is it something else?

If the difference is the version of Thunderbird, then how do I get 147 on my Fedora machine?

If it is something else, what do I do so that I do not lose saved emails and calendar data from 147 version when I am running the 146 version?

I'm running Thunderbird on Mac OS 15.3. I have two POP accounts in Thunderbird; the configuration has been stable for years. This evening, I went to add a new account, and Thunderbird seemed to have decided to update itself, including flipping me over to Chrome where it opened a page about Supernova.

Thunderbird relaunched and came up with an empty "Chat" window. My usual mail window is gone -- and I can't get it back. I can't get an "About Thunderbird" window to open.

I actually can't figure out what happened. My mail appears to be gone. My accounts seem to be gone. I can't open Settings, I can't open Account Settings.

Wait, the mail accounts seem to still exist -- I can tell Thunderbird to check mail, and the POP server shows the checks happening -- but if I send mail to myself, nothing opens. Also, all of the Layout menu options are greyed out.

Help? :-)

Thanks, Vince

1. How can I locate the FF version on my devices. I have Android 14 OS. Today (February 16) I located a versio 147.4 will be released. Is this automatically available for my devices or do I nèd to download. If so how.. Ðo I get notifications.

Hello, I have Mozilla Thunderbird version 128.12.0esr (32-bit) on a Windows 10 laptop On the Help/About Thunderbird it says update failed. I have clicked on download and have version 139.0.2 in my downloads folder. When I try to install it all goes well until I get a message "Your computer must be restarted to complete a previous uninstall of Thunderbird. Do you want to reboot now?

Yes No " I have rebooted several times now with the same results. What do I need to do to get the update Regards Peter Norris

I let my Firefox update not even an hour ago. I went to right click and copy some text and the menu is now BLANK expect for "Search Google". I copy and paste in the browser A LOT. I need this fixed. Next time you guys push out an update I'm going to ignore it.

My folder header has many extra icons that when click do nothing -- happened when updating to 152.0 (and I need to hit ALT several times for the command line to appear to be able to "view folders" Tbird doesn't load to them automatically ! )

Here's a screen scape -- note the "what looks like a document" goes on and on and on if I scroll right

Hello, I reported this problem and you replied with a solution and that was to downgrade to version 142. My question is: Then what ? Will I be stuck with version 142 for years or is Thunderbird working on a solution to this problem because presently updating to any version such as 144 only continues to erase local folder contents. Thank you for your support Douglas Noades
