I tried to change my password but could not find an acct key, don't even remember having one! This is a new computer and it worked fine until I say that you are showing a very old picture for my account and showing I'm still on Windows 10!!! That is VERY OLD and I've used Firefox for years!!! I changed from Windows 10 to 11 on 7-1-25. Someone has hacked my account I guess!
What to do???

bold textAfter waking up to no sound, I updated firefox, to no avail. Not only do I not have sound on fb or ig youtube, they all work on other browsers. Again, it has been updated, can't find a setting anywhere, just no sound from anything related to this browser. Please respond asap or I will switch for good. I don't want to, as I have many things saved here, & a good workflow, but...unacceptable I can't contact anyone about this either. Not ok. Please advise.
I tried changing my password and it would not accept the 72501823 code you sent! I entered it but it just sat there without moving!

Hello,
We’re developing a headless, accessible interface to Thunderbird for blind users, and we’re integrating with the browser.messages.list() and browser.messages.query() APIs to access email content.
We’ve encountered an issue: the Thunderbird web extension API requires messages to be downloaded and stored locally to access their full content via the getFull() endpoint, but there appears to be no way to programmatically trigger a message download from IMAP using a message ID or header.
To minimize disk usage, we only want to store the most recent 30 days of messages locally. However, when we enable “Synchronize the most recent 1 month” in Account Settings → Synchronization & Storage, Thunderbird begins syncing from the oldest messages in the account (starting in 2008), rather than downloading the most recent month (e.g., June 15 – July 15, 2025).
My questions: Is there any way to configure Thunderbird to download and store only the latest (by date) 30 days of IMAP messages?
Alternatively, is there a way to use the WebExtension API to access the full content of recent IMAP messages without syncing the entire history?
I'm currently using Thunderbird 128.11.0esr on Linux (MATE desktop).
Any advice or workarounds would be greatly appreciated!
Thank you.
If I put an email message in the Outbox. Fow how long would it be there? Shall I do something by myself to make sure it is going to be send?

I'm trying to setup tbsync to use with Google Contacts. I'm running 128.12.0 esr. I've installed tbsync and Google-4-tbsync.
I followed the instructions to create Google credentials, but where do I put them? And the account setup for tbsync asks for a "client secret" - what's that?

Context: Here is an animation I generate with a program I'm developing. It being an SVG makes it useful to open in a web-browser. In chromium based browsers I have smooth animation, while in firefox I get much worse performance. At larger animations the problem becomes much more apparent. This is the approximately the largest animation that firefox can handle without lagging too much.
Expected: Firefox should have comparable SVG animation performance as chromium.

20 years of emails apparently gone. I have been trying to add TB to a new laptop.
I used the export function in TB and was directed to create a zip file since it was over 2GB. I used 7Zip to view the file and it did not show up in the program. I did this a few times and it kept doing the same thing. When it actually worked I got about 2% of the emails. I believe that, as a result of doing this, that the profile was corrupted by the process of creating a zip file. The result? The original profile on the old laptop is no longer valid. Most of the time when I tried to unzip the file it displayed an error message. I have been through so much over the last few days I cannot remember the entire error but it had the word invalid in it. A red banner across the top of the screen.
I have scoured all my devices for profiles and have tried every one I could find. I was told that using old profiles without them going through the process of TB versions that unexpected results may happen. The latest result, which happens with every profile I use is what is in the attached image. Nothing in or under the inbox, and all this under the outbox.
Is there anything I can do to fix this?

Peer Certification expiration - Why is this Pop-up showing up after many years of thunderbird use and why does it prevent receiving and sending emails. It wants a certificate or an exception with out adequate explanation or guidance.
I did not have account set up and because I couldn.t receive email confirmation could not seek help. I contacted Norton who appeared on the company example and they could not resolve. Given I could not get access thunderbird for assistance, I did an uninstall and reinstall. I lost my addresses but at least I was able to sent and receive emails again. the Pop up had gone away.
I set up my second email and when I completed this set up I was greeted by this pop-up. What is this all about and what are the risks. How is it resolved?

Hello... So, a couple of weeks ago, there was a 15-hour blackout during a Windows 11 update. I had exited firefox, and was shutting the laptop down, and it asked if I wanted to update and shut down (or other options). I chose update and close. When the lights came on and the router booted back up, Windows finished updating. It works, but here is the rub: whenever Ffox runs, a couple of minutes into the sessions, it will start displaying previous session screens, screen saver-like: one after the other every ten seconds or so. I can't X out, because it disappears whenever I move the cursor. The images appear not only on Ffox, but cover whatever other app's screen until I move the cursor, which is irritating when you're trying to meet the deadline on a novel! Please help! I am running version 140, by the way.
Is there a registry hack to over ride and set mozilla as the default browser. it is annoying to have to set as default every time.

Hi, I wonder if anyone has had a similar problem - since a few days I get an immediate SMTP timeout in Thunderbird for some mail servers but not all. For Outlook the same server works just fine. Version 140.0.1esr has recently been autoinstalled. It is possible that the problems started when that version was installed but I am not sure about the timing. The email provider has no explanation and claims there is no problem on its side. Also, Thunderbird has recently asked me to confirm a server certificate for receiving emails. Usually when that happens I also get asked the same question when sending emails, but this time I did not get the question for sending, I just get the timeout message.
Thanks,
Magnus

The following problem has occurred at least three times, each with a different organization. In making an online contribution, I first enter my personal information-name, address, email, etc--and then move on to enter credit card information. When I enter the credit card information, the personal information disappears. When I re-enter the personal information, the credit card data disappears. Eventually, I wind up calling the intended recipient and giving them all this information verbally. What is going on with Firefox? How can this problem be fixed?
