I recently installed Thunderbird for use with Gmail. I have created several message filters, but they keep disappearing. I have found that multiple filter files have been created:

Directory of C:\Users\shrdl\AppData\Roaming\Thunderbird\Profiles\ae352sn6.default-esr\ImapMail\imap.gmail.com

2025-10-28 22:30 385 msgFilterRules.dat

              1 File(s)            385 bytes
Directory of C:\Users\shrdl\AppData\Roaming\Thunderbird\Profiles\ae352sn6.default-esr\Mail\Local Folders

Any idea why this is happening? Thanks

I have deleted the account along with the saved password for the account in question yet I keep getting requests to verify identity and have no way of deleting the account when it appears. My other google accounts are fine but the one that keeps requesting verification is a work account which is no longer used. The message comes from apidata.googleusercontent.com Any help to remove this so the message doesn't keep appearing Roger

Hi, I've set up TB successfully on a new PC and been using it a while. Then I noticed my local folders archive group of subfolders was missing. I followed some instructions about moving local folders file across from the old to the new version.

Now I see the individual archive folders without the folder group name 'archive'.

Also, there are a couple of other files not visible on the new platform although they were in the original installation local files and were copied across.

I was careful to ensure the same version running on both PCs. Also that TB was closed when copying files across.

Any pointers appreciated!

I'm experiencing random (every few days) audio issues on 140.4.0esr on Debian trixie. Sound would randomly disapear. Firefox doesn't show on pavucontrol. Restaring pipewire doesn't help. To resolve I have to wipe FF profile and start from new profile. It is very annoying. What could be causing this problem?

Thank you.

I need a way to recover open tabs, history and bookmarks when firefox crashed. I type placessql and session in firefox profiles folder and nothing comes up. Firefox won't open at all and I asume if I reinstall it I'll lose all previous sessions. What files I need to copy before reinstalling?

Dear all,

Previously Thunderbird has been saying that I had several unread e-mails in my Inbox. But I was unable to find them.

This morning I opened my Thunderbird and had my e-mails in the Inbox. Then a moment later all the e-mails disappeared. Yet it was still saying that I had five unread e-mails. Thunderbird prompted me to Compact Now which I did. I would be grateful if you could explain me how I can recover my e-mails. Thanks.

Kind regards, George Nielsen

I access my gmail account via Thunderbird for years and everything viewed perfectly untill a few weeks ago when all I was getting the subject as links only, You can see this in the 2 screen shots I included . How can I go about fixing this please  ?

Ich bekomme ständig folgende Aufforderung: Authentifizierung erforderlich - Mozilla Thunderbird https://spica.t-online.de verlangt einen Benutzernamen und ein Passwort.

Win 10 - TB 64 bit 128.9.2 long working ...... NEW error.

Pop up asks for PASSWORD ..... has not changed ..... does not work (loops)

Has 2-factor .... still worded fine

Pop up with URL says only EDGE: too many requests (moved from 5 to 3 ... no help)

Web access to that Yahoo Mail works ... same password.

I recall - I THINK - same thing with a different Yahoo Mail account .... access via web, then got a pop up about allowing THUNDERBIRD. Clicked it and no issue since. Not happened with this account. Tried switch to "Normal Password" .... no joy.

I'm looking for the Thunderbird for Android user manual. Is there something like that available to read? All I found was scattered FAQs.

No, I don't have a specific question. I just want to read the whole manual.

Hi

Recently, I have been testing the functionality of my website using Puppeteer, but I found an issue with the file names when operating the Firefox browser through Puppeteer. When the user clicks the download button, my JS code generates a series of special file names. However, when I use Puppeteer, the file names seem to be truncated. Additionally, I have configured the BIDI protocol while using Puppeteer.

For example: When I manually open the firfox browser and click download button, the file name I get is ANTLMonitoring_MRBTS-530377530377530377_Wroclaw_class._2!__________+-=~,*@#$^&*()￥'.{}[]*;中文Приве..*TEST_123_20251028-0409.csv But when I perform the same steps using Puppeteer, the downloaded file name is ANTLMonitoring_MRBTS-530377530377530377_Wroclaw_class._2!__________`+-=~,_@#$^&_().csv (puppeteer)

Comparison: ANTLMonitoring_MRBTS-530377530377530377_Wroclaw_class._2!__________`+-=~,_@#$^&_().csv (puppeteer) ANTLMonitoring_MRBTS-530377530377530377_Wroclaw_class._2!__________+-=~,*@#$^&*()￥'.{}[]_;中文Приве.._TEST_123_20251028-0409.csv (Manual)

In both manual testing and Puppeteer testing, I used the default browser configuration. The operating system tested is Windows 11, and the browser version is 144.0 (64-bit). Can anyone help me with this issue? Thank you very much!
