Probably my falt, the last version of Thunderbird got instaled on my PC. I do not like it, impossibility to read my message on the side of the screen, impossible to reorganise mails via there date after they reorganised themself throw sender order... So, I would like to go back on my old version, probably 143 or 144 ? Does anybody know how to do it without loosing all my data ? Thanks in advance... Pierre A.

I am using Thunderbird across multiple devices. Generally this works well, but I recently created a new sub-folder in my Inbox whilst on my Thunderbird Android account (v13.0) and moved a number of messages into it. That sub-folder is missing when I return home and open my desktop installation (140.5.0esr 64-bit). At home I am running Windows 11 Pro v25H2.

Is there something obvious I can do to bring this sub-folder and its contents into my desktop Thunderbird set-up?

I tried adding the sub-folder manually on my desktop Thunderbird installation but the folder would not appear.

Help appreciated.

Google Search is pinned at the top of my Firefox Suggest list. (see the attached image)

Google Search is NOT my default search engine.

Where is this controlled/specified?

FF 145.0 Mint Linux/Cinnamon FF installed as system package not flatpack

Hi! Downloaded Thunderbird on a newdesktop computer, also had it on my old desktop computer, I used to read the emails underneath the email title.

Now it comes on the right side of the screen, i dont manage to change it myself.

I have just had an upgrade to version 145.0 but cannot select any of the optional layout formats that I had in previous versions as they are all greyed out. Why is this?

Hello,

When I try to save attachments from emails directly on my Computer, they never arrive at the destination folder - not individual files nor "save all attachements". Although the procedure '(left button menu - save - [navigation through file system till to the destination-folder] - save here') is "normal" and does not give any error message.

I can only save attachements, when i first open them (e.g. in word), and save them from there in its destination folder. This is quite a complicated procedure .. one should be able to save attachments directly from Thunderbird, without opening it.

What is the reason for this problem? Are there any options, is it a local problem (but it is a brandnew Laptop) or is it a bug in Thunderbird?

Best, Renate Albrecher

I already have Thunderbird installed on a laptop. IS it possible to export my inbox and view the emails on a desktop without having to create an email account on the desktop?

bold text When in "Local folders" , I had icons for "New Message" and a spot that I could right click on to get new messages from certain servers or left click to get them ALL. Where did they go ?

After upgrading my Firefox to version 145, a blue line appears at the top of the browser window when it's in full-screen mode and the current window is focused. I know this is to remind the browser window that it's currently focused and interactive, but I really hate this notification and want to make this conspicuous blue line at the top of the window disappear. I couldn't find a relevant option in the Firefox browser settings. Does anyone know how to set this up?

Please help me to disable this focus tip,thanks!

Last night I updated my iPhone 11 Pro to iOS 26.1

Since the upgrade I'm unable to have Firefox play audio for a music stream I listen to when the phone goes to sleep/lock or if I use the app switcher to switch to another app, like Maps.

This wasn't happening yesterday when I was using my phone and listening to the same audio stream in my car with Maps open for navigation.

Hello, After performing a clean install of the OS, I logged in to my firefox account. But it is not syncing the passwords. I tried installing firefox to my phone, also not syninc. I think btw, it is syncing but my passwords are not there. Here is the log: https://pastebin.com/DH0wuERM Any help appreciated, because there were more than 200 passwords there. Thank you

When I sign in to the NY Times (for example) I get a dropdown of autofill email addresses. Some are even mistyped addresses or bogus addresses I've used to access webpages that'll take any email address. I cannot delete these. I've tried shift-delete. These email addresses cannot be accessed via Firefox preferences: autofill screens do not list email addresses but only the physical addresses that I've saved.

(And then, of course, the minute you submit any email to the NYTimes it immediately creates an "account" and starts sending you subscription offers.)

Confused. Version 144.0.1 | Released October 16, 2025 Says 32 bit. I thought I downloaded 64 bit.

Problem: Freezes when I click anywhere on TBird desktop

How do I address the freezing problem?

Thanks Robert

Chase website now requires Mozilla Firefox update 128 or higher to access accounts. My version says my version (115.30) is latest update. Do I need to find a different browser or is there a solution? I am using Windows 7 Pro desktop. Thank you.

Does Mozilla / Firefox have a password manager for families - similar to bitlocker or Nordpass or others?

If so, where can I find it and how would I set it up?
