Tuesday Oct. 7, our ISP converted to a new e-mail program. I could NOT log in/on I called our ISP's help desk. The 'technician' could not help me log in to our Thunderbird POP 3 account. He had me, WITHOUT asking if I had essential - legal - medical-etc. e-mails in the IN BOX or in folders! He NEVER warned/cautioned all ?would? be lost - GONE.

I URGENTLY need to recover all TB POP3 IN BOX & e-mails in folders. I need to access legal messages today, if possible.

If Mozilla does not have a recovery program, what do I do? I am not seeking to recover ' deleted messages (unless his having me change from the POP3 account to a 'new' IMAP account is the same as ' "delete" '.

Any & all prompt responses APPRECIATED! Remain WELL & Be SAFE!

Hi, I've been using tab groups for a while and i had some pretty important tabs save there. I wanted to know if they get deleted after a while or not, Because all of mine suddenly disappeared. And also is there anyway to get them back?

HI all. This is a good one. I recently got a MAC, my first one, so dont know much about it. I installed thunderbird and can receive via IMAP but cant send via SMTP. I have smtp setup EXACTLY how it is on my windows PC which works. When I hit send on a message, it immediately comes back with "Sending of the message failed. The message could not be sent because the connection to Outgoing server (SMTP) <maileserver.com> timed out. Try again. This message comes back immediately, as in .000001 second. This particular mail server I own and is on my network, and checking the logs, the request never even gets to the server, so its not a server issue. (Again, it works for all my other devices and other clients). server info, password etc are correct. I tried deleting the account and recreating it but no go. From a command tool, I can telnet to my mail server on port 25 and it answers and I can interact. If I use the built in mac mail client, it works fine. So this is definitely a thunderbird issue from what I can tell. Thunderbird 143.0.1 (aarch64) on 26.0.1 (25A362) Any tips appreciated, Im ready to take a bath with a toaster. Thank you!

On all our computers it seems impossible to sign into Outlook...several laptops and 3 desktop...even a new Apple device. Enter your email address and then taken to the next page (see attachment). sign in works with Edge! This has been happening for maybe a month. Very frustrating! NEVER opens the next security window, the 'spots' just keep moving forever...selecting "Back" just repeats the cycle.

Since the recent Firefox upgrades, I am no longer able to log into the social security site using ID me. Previously, I logged in with no problem but now get a 400 error message saying the website is too large. Of course I have emptied cache and cookies and reloaded Firefox but nothing works. Apparently the error lies within the Firefox upgrade since before upgrading, there never was a problem logging in.

Can the notification for upgrading be controlled on ver 143 on linux. It keeps appearing and as a user I should be able to silience or have it notify me at a period I prefer instead of interrupting browsing.

Using version 143 PIP does not work on different workspaces. If I open PIP the PIP only remains on the desktop that FF is on and the PIP disappears on othe workspaces.

thunderbird won't start after installation giving message that a version is already running. I end the task in task manager and it doesn't help, then restart with same erro. I tried deleting the parent.lock file from the profile and that didn't help. What next? Has anyone solved this issue?

The issue started about one week ago (today is 10/11/25). When I wanted to print while in Firefox browser, the print never executed. Instead the screen froze as did the browser. I had to do some experimenting to use my pointer and open a different browser. Yes - besides the pointer being frozen (all that showed was an hourglass) my keyboard was also frozen. When I finally opened a different browser and printed the same item, no problem. I had to close Firefox to be able to fully use my laptop again. I searched the solutions and none had an effect. Firefox would still freeze/hang/lock up when trying to print. The browser is up to date.

In one of my Firefox installs, the Profiler automatically starts recording every time I open Firefox. There's a button on the right that looks like a speedometer and it is blue until I tell it to stop. Then it is taskbar button color.

Profiler instructions at https://profiler.firefox.com/docs/#/./guide-removing-profiler say to simply drag this button off the toolbar and it will stop record. On restart, it's back on the toolbar, and it's recording.

I have tried refreshing Firefox. Doesn't help.

I have tried uninstalling and reinstalling Firefox, and then setting up a new profile. Doesn't help.

I have tried deleting prefs.js. Doesn't help.

I have tried opening up the developer console, opening settings, and unchecking "performance." Doesn't help.

I searched the registry and found a key called MOZ_ENABLE_PROFILER (iirc, something like that). I set it to zero. Doesn't help. I then deleted the key entirely. Doesn't help.

How do I get rid of this thing? It must be a registry setting of some kind, as it appears in whatever Windows account I open Firefox from, but I can't find it. It is deeply frustrating as the computer it is happening on is my oldest computer, and I don't want a recorder running in addition to Firefox.

On my linux system, I have two users. If I log in as user A and use FF and leave a bunch of tabs open, I can view those tabs again later if I restart my computer and log in as user A, so FF remembers its history.

No Problem Scenario Logged in as A - open FF - open a bunch of tabs - CLOSE FF log out of A log in as B - do stuff log out of B log in as A - open FF; all the tabs are there

Problem Scenario Logged in as A - open FF - open a bunch of tabs - leave FF open (don't close FF before...) log out of A log in as B - do stuff log out of B log in as A - open FF; all the tabs are GONE

If I run into the Problem Scenario, I can sometimes use these steps to get the history/tabs back. https://support.mozilla.org/en-US/kb/how-restore-browsing-session-backup

Whether the steps work or not, the Problem Scenario is annoying. I don't know what causes this. My desktop manager is KDE.

When trying to add my outlook.com email account to Thunderbird 143.0.1, using the instructions at https://support.mozilla.org/en-US/kb/thunderbird-and-exchange, I get an "Exchange auth error." I'm able to add the account manually using imap, but I want to use Exchange so I can access my outlook.com calendar and contact when TB is updated to include them.

Search setting is set to All for search server limit. However search doesn't work. Nothing is returned. I click search messages on server and nothing comes back. When i look up the same search criteria in Gmail i get email back. Why is search not working properly for me?

My Thunderbird calendar refuses to display dates in European format, namely day-month-year. I have read lots of helpful hints on the forums and tried everything, but nothing changes. My system is Ubuntu 25.04 with Cinnamon 6.4.8. Thunderbird version is 140.3.0esr (64-bit). Some of the suggestions refer to settings that are no longer there compared to earlier versions. For example, Settings > General > Language and Fonts has no format options. I have also used the config editor while TB was not running and added ntl.date_time.pattern_override.date_short and ntl.date_time.pattern_override.time_short, without any effect. Dates in the calendar still always appear in the illogical American month-day-year format. This is confusing, to say the least ! Has a solution been found to EASILY select the locale and formats that should be used? At the moment, the settings are under different menus and in different locations, and TB seems to be making it as difficult as possible to get these set - permanently ! - to the user's preference.

Hi,

the password manager (about:logins) is a very handy feature, i use all the time. However, tehre is so many pages where the FF password manager fails to suggest the correct login user name to fill in the "user" field. (Interestingly, the password fill is much more accurate).

To start with: for logging in on THIS VERY SITE for posting this question, I needed to:

1. manually open the FF logins page
2. enter the url "accounts.firefox.com" for search
3. pick the entry
4. copy the username
5. swithc back window
6. paste and confirm.
7. repeat for password (I think - or came this at least suggest correctly maybe)

What's going wrong? Is my installation broken - or is this for all users the same experience?

Tks

Hello, I recently purchased and started using the Hyperx Cloud 3 wired headphones. When I watch a YouTube video or shorts with these headphones, if I skip forward a few times or scroll to watch a new short, a loud popping noise occurs in the headphones. I turn the volume up and down, and it fixes it. Interestingly, this doesn't happen in other browsers, only in Firefox. This is very interesting, and I can't figure out why. I wanted to share this with you because I love Firefox.

NOTE: There's no problem with the headphones; they work perfectly. This is an issue only in Firefox.

For some reason (accidental key stroke?) one of my email account's folders are no longer arranged alphanumerically. How can I reset the order to alphanumerical? I can't find a menu item or setting to do this. Thanks
