Hello,

I have been unable to update Firefox past 132.0.2; every time I download an update and install/restart, all tabs automatically crash upon loading regardless of the website. I can load local pages like settings or about:config, but anything that actually uses the internet goes straight to crashing (including sites as simple as google.com). I have tried restarting in Troubleshooting mode to no avail. There are no crash reports when I pull up about:crashes, so unable to post IDs here.

It is not an internet access problem (I am [unfortunately] filling out this form from Edge), and with reversion to 132.0.2 everything moves along hunky-dory. I am also able to use the newest version of Firefox on all of my work devices, so it appears to be something in particular with my person PC. Problem occurred with both Windows 10 and Windows 11.

Any help would be much appreciated- I didn't mind an older version of Firefox that worked, but there have been some MFA logons that refuse to go load in v132 so it's becoming something I'm less able to ignore now. TIA

... click on (eg.) 'Interactive Map' and nothing happens, at least not here. Chromium has no problem.

How can I specify which Thunderbird account is used when MAILTO is used in html? I know I can change the account to what I want after the new message window comes up but I always forget.

Pas moyen d'ouvrir Firefox depuis une clé usb de démarage. On me demande un code par courriel que je ne peux pas ouvrir. Je suis bloqué car je tombe toujours sur le Bios quand je veux avoir accès à mon ordinateur. Commenr m'en sortir De l'aide SVP Merci

Please tell me how to stop this. I have spellcheck enabled and a English (UK) dictionary selected. This problem has just started. My computer is old now and I'm running Windows 10. I had to do a 'hard shut-down' recently when my computer was unresponsive - might this have caused the problem? This underlining is only happening in Thunderbird, not in Word for example. I would be grateful for a simple solution as I'm not very computer-savvy.

Twice in the last fortnight Thunderbird has lost all email passwords - the Tools/Settings/Privacy and security/Saved passwords just leads to a blank box where the passwords usually are. Thunderbird will no longer collect email and keeps asking for passwords for email accounts. This happens even when the option to 'save password' has been selected. I think this is probably happening at the point when the PC is rebooted. Thunderbird version 153.1.1esr (64 bit) and Windows 10. Using System Restore has not resulted in recovery of passwords. Several different email accounts/email providers are involved - outlook.com, tiscali.co.uk and zohomail.eu. Broadband provider is Zen.

I notice that the Appdata/Roaming/Thunderbird/Profiles/w2anb37y.default folder contains a number of files named with such names as 'logins.json-8.CORRUPT' - with 'Date Modified' being mostly either 17th August or today 31st August - so it might look as though password data is becoming corrupted.

Can you assist?

This is probably not a T-bird question, per se, but it is so strange it seems that this might be the best place to start, hoping someone might have some insight.

My wife and I each have our own laptops, running Win-11 Pro. Each laptop has T-bird 153.2.0esr (32-bit). We each have an account to yahoo mail (the site now hosting our Comcast email accounts). No problems since ... forever. Until today.

Now, beginning today, on my wife's laptop, when she opens T-bird, she gets a pop-up logon page, pre-loaded with her userid/email address. No input field for a password, but that it not unusual, as a lot of sites put that on a follow-up. But when we click 'next', it just rejects it. We were able to log into the yahoo mail web page (in Firefox) just fine.

After a lot of head scratching, I added her account to the T-bird configuration on my laptop. First time up, it prompted for credentials, but here it accepted them. So now we have her yahoo/comcast account configured and working just fine on my laptop, but continue to get credentials rejected running the same config on hers. Again, this has been working just fine up until today.

(If you are wondering about the connection between Comcast and Yahoo, several years ago we 'cut the cable' with Comcast, after confirming they would continue to support our email accounts. Then some time ago, they off-loaded that to Yahoo, such that we were able to retain our Comcast email address, but it redirected to and is hosted on Yahoo.)

Depuis Firefox 150 il ne m'est plus possible de Glisser-Coller un dossier avec ses fichiers dans un dossier de mon NAS Synology. Le service d'assistance Synology m'a apporté confirmation. Voir sa note en attaché.

Il semble qu'il y a un "bug" dans Firefox 150 et plus (j'ai le 155.0.1) pour ce Glisser - Coller ?

Que puis-je faire ?

Aloha. I'm helping a friend with setting up a new Windows 11 PC, and cannot get Thunderbird to connect to Spectrum's servers. I spent an hour on the phone with Spectrum support and they just gave up and said it must be an issue with Thunderbird. Here are the details:

- Brand new Dell 24 All-in-One EC24250 - Windows 11 25H2 plus all additional fixes. - All Dell drivers updated. - Thunderbird V155.0 64-bit

If I click on 'Get Messages' after a while I get: "Connection to server mail.twc.com timed out". I've gone into the config editor and changed mailnews.tcptimeout from 100 to 500 and still get the error.

In the Account Settings | Server Settings | Test server connection I get: An error occurred connecting to mail.twc.com:993.

I've tried this with both setting up a brand new account in Thunderbird, and also via copying the 'Thunderbird' folder from %appdata%\roaming from her old machine.

Email configuration (from Spectrum).

IMAP Settings Server name: mail.twc.com Port: 993 user name: abcd@hawaii.rr.com Connection Security: SSL/TLS Authentication method: Normal password

SMTP settings Server Name: mail.twc.com Port 587 Connection Security: STARTTLS Authentication method: Normal password

Can anyone help me troubleshoot this scenario?

I made a change somewhere that caused a total loss of history/open tabs even in my tab manager extension. I can't remember exactly what it was I changed but nothing I have searched here has been helpful in recovering from this. I did not want to bring my profile from home as I am using Firefox here in a work environment. Can someone point me to or explain a step by step method to be able to do this? Nothing I found in searching here has been positive.

I have a recurring email which is spam at it's worse. I identified it as spam/junk, ran the filter as instructed. Will not go away. Is there anyway I can permanently get rid of it? ecare.all.r@emaildl.att-mail.com

Helping a friend with her HP-i3 PC running Windows 11 that I setup in March of 2025. It was a new PC purchased from BestBuy in March 2025.

I had to restore the image backup of her C drive that I did in March 2025 because of a Windows problem that I wasn't able to resolve. Now that problem is resolved but Tbird has the old profile folder without her new email contacts. (Unfortunately, I did not remember to use Tbird to save a backup of her profile folder before doing the restore.)

She has a recent image backup so I can extract Tbird's profile folder from that backup. What would be the correct procedure to replace the current profile folder with the one extracted from the recent backup?

(don't currently have access to her PC so don't know the version number of Tbird currently installed)

Lately, whenever I click into a youtube video from within youtube, instead of Firefox blocking autoplay, it mutes the video but lets it play.

Initially, it was muting EVERY video I pulled up, but messing with my settings has fixed the problem if I click into a youtube video from elsewhere (ex. a google search result), or if I refresh the page. It's super annoying to having navigating youtube be this non-functional right now, though, since everything just silently plays until I catch and unmute it! Any help would be super appreciated!

(I'll attach an image with my current autoplay settings.)

I have Win11, Thunderbird Windows MSIX packagethunderbird-MSIX - 1.0, and several accounts (The box below won't take anything past "Thunderbird Window.")

I'm looking for some way to make a different ring either for one of the accounts or for certain domains or for a subfolder -- any way that I'll know when something comes in from specific domains. The special ring(s) can be for each of the two domains or both of them. Can that be done?
