Hello, could you please let me know if updating Firefox as suggested (version 128) will be compatible with my iMac OS X Version 10.9.5. Thank you very much. Kind regards AS.

Got this error message on recent update and now Firefox doesn't work at all. Platform Version '131.0.3' is not compatible with minversion >= 131.0.2 maxversion <= 131.0.2

I was automatically updated to 128.2.3esr (64-bit) and immediately I have lost the ability to create new subfolders in any part of my folder tree or on any of the accounts I use. Rt-click -> New Subfolder has always opened a little dialog box to name the new folder. Now nothing happens. I have seen a similar user issue reported, but the answer was long and incomprehensible and seemed purely to relate to spam boxes and certain user account types . The issue is still not marked as resolved and is a real pain. Is there a simple way to roll back to the last version while you figure it out?

Best Regards

Peter Rose

Hi, after an update, i have the newest version of Thunderbird installed. Upon starting, it says: "Unable to use profile when you launch an older version of Thunderbird." I cannot start the program. But it is the newest version... What can I do? Thanks Lukas

Dear All,

I think that is a compability problem of Citadel with Thunderbird email client.

After several steps to try to solve the problem I found that Citadel is not compatible with the last version of Thunderbird.

I tried Linux (Centos 9) and Windows Thunderbird. I tried my affiliation network and with my mobile hotspot.

I can send emails with my Android email client.

I am thinking to make a downgrade of Thunderbird. I have there all my emails from always.

But first I have to backup everything of Thunderbird. Time consuming task.

Some help is needed.

Having just re-installed Thunderbird I receive the following error message when trying to set up my gmail account, which had been working fine before

400. 

That’s an error.

The server cannot process the request because it is malformed. It should not be retried. That’s all we know.

The password is correct as I can login from my browser and I have easily setup my other email accounts - not gmail. Also have re-started PC and Thunderbird.

Help please, regards, Haydn

A new version of the "List All Tabs" appeared on my toolbar today, shown on the left and hovered over in the attached screenshot (ignore the Malwarebytes extension icon). The old icon for this button was a chevron with approximately the same functionality. I was able to remove the old icon, but I'm unable to find a way to remove this one. Here is what I've tried so far:

• Like the old one, the Customize Toolbar feature is unable to remove it since it is grayed out.
• For a while, I was able to remove the old icon by going to about:config and setting browser.tabs.tabmanager.enabled to false. This solution does not work for the current and some recent versions of the button.
• I attempted to create a userChrome.css file (following all the steps according to this this website) and added the following string: #alltabs-button { display: none !important; }

None of these attempted fixes have removed the button following a browser restart. Is there a way to remove it? I have no need of a button that shows me what tabs I have open when I can simply look at my toolbar.

How can I configure the FireFox application on my macOS device (M2 Pro) to auto-update in the background while the app is not running?

Thanks in advance!

I have a IP intercom that only works with Firefox 127.0.2 Now Firefox automatically upgrades to the latest version and I'm unable to prevent this. I'm unable to manage my intercom with the latest version. How do I turn off automatic updates.

I have latest version of Firefox for Windows 10 and about 2 weeks ago the Last Pass extension from your website stopped loading correctly. The extension installs in the toolbar, but does not work. It partially loads and then freezes up. I was able to resolve by removing extension and then going to Last Pass's website and downloading their Last Pass 4.0. Your extension is messed up. Tom Weaver

Hi,

I am running Thunderbird 128.2.0esr (64-bit) on Ubuntu 24.04.1 LTS

Since around the beginning of September, I find that my Local Folders, which still seem to be storing new emails ok in Thunderbird, are no longer mapped to my "~/.thunderbird/<profile name>.default/Mail/Local Folders" directory tree.

Thunderbird seems to have changed its behaviour in this regard around the start of September.

Has anyone else experienced this?

Any idea where the "Local Folders" emails might now be stored on disk?

I converted as advised and then updated to the newest version. I lost everything except the messages: the Address Book, Tags, Message Filters, and Folders are all gone. This is a disaster after 15+ years with Thunderbird. It started when I copied the folder "profiles" from my laptop to my PC for the 1,000th time. Is there a simple step-by-step solution? Without the history or apologies etc. etc? Just "do this?" My solution now is to do all my email on my laptop. Ugh!

Had to re-install Windows 10 Pro 64 bit. Saved Tbird Profiles folder to USB thumb drive. Re-installed Windows then installed latest Tbird version (same one I was using). Opened Choose User Profile > Selected Create Profile > Selected Use the selected profile... > Exited Choose User Profile.

Then went to the thumb drive > Opened a profile folder > Copied everything > Then pasted it into the new profile folder I had just created. Opened TBird but it didn't have any of my settings or emails.

The thumb drive had 3 profile folders in it so I repeated these steps for each folder. But still didn't get my settings, etc.

What am I doing wrong?

I uninstalled thunderbird and when I try to reinstall it I get a "cannot find temp archive" message.

I've installed thunderbird for another user on the same computer and had no trouble.

Can anyone help me? Thanks so much.

I downloaded Thunderbird, set it up with 3 email accounts played around with it all afternoon, closed it then when I try and open it back up it's like it's not there at all. It takes me back the the 'thanks for downloading page and opens the bit for me to set up a new email. There are no folders there at all. All I can do is start afresh and enter the email addresses again. This can't be right???....

After auto-update to v128.2.3esr all my rss-feeds are broken. The main rss-folder Account Name has changed to "server8.invalid" and all contained rss-feeds are colored gray and are unable to fetch new messages. How can I fix this?
