Every time Firefox updates it keeps re-enabling settings on its own.

Specifically 2 settings on the general tab keep enabling themselves in the "browsing" section, "Recommend extensions as you browse" and "Recommend features as you browse"

I have disabled these settings dozens of times now, and every time Firefox updates it keeps re-enabling these 2 settings on its own.

Just now I updated to v128.0 and these 2 settings turned themselves on again.

Why is Firefox not respecting my settings? Why is Firefox allowed to modify my settings without my permission?

I have deleted and reinstalled Firefox already. I don't use profiles and am not signed into the browser, so no settings are getting carried over that way.

I've hit the refresh button 1000s of times to get halfway through my emails I'm still a few months from current it downloads 1-3 emails most of the time when hitting refresh all. And most of the help I found for this stuff is very out of date.

Hello, I am using TB Version 115.12.2 (32-bit). Overnight Xfinity is asking for a password to download my email from the imap mail server. ("Login to server imap.comcast.net with username *something*@comcast.net failed") .Comcast (Xfinity) tells me the problem is with TB. As I stated, this happened overnight. I made no changes whatsoever! Can you please offer some resolution? Thanks, John

I keep getting messages that the hotmail server is down or that I need to reenter my password. with ms going to a new authentication protocol why is there no information on this site on how we can continue to use tbird with hotmail.

This is my crash ID: bp-ff99f648-78ab-4cad-b1f5-7aaa70240902 I've already tried troubleshoot mode, same result. I do have a userContent.css file, but deleting it makes no difference, and I can think of no other major change I've made to my installation.

I would prefer not to have to reinstall Firefox.

Thunderbird used to have a panel on the left-hand side of the screen which listed folders such as bin, sent, etc etc. This has disappeared and I do not know how to access folders such as bin, sent, trash, important etc.

I tried to do an import of a backup profile that was very large, greater than 3 GB. System says this file is too big to recover. Error console is as follows:

Sometimes when I consign an email to the trash and then need to re-read it later, it's turned into gibberish. A tiny fraction of a recent is below. I've used the "repair text encoding" feature, without any result. If I scroll further down in the gibberish, there are links that weren't in the original email and would have had to be sucked in from other emails in trash, which I just don't get. I can go back to the email on my phone, but on my desktop, they are hopelessly jumbled. What causes this and how can I stop it? Thanks!

As stated, Thunderbird 128.0user Nebula only download around 448 messages from my shaw.ca mail server. The download starts with the earliest messages on the server, thus no current (latest) emails are downloaded to Nebula. I am short about 3.9k messages in this example. I am using pop3 as "I need the independency" on this computer. Earlier versions of Thunderbirds has no problems keeping up to date with all my accounts and their message volumes.

Thx.

I have latest version of Thunderbird with a number of email accounts (Gmail, ionos, yola, etc.) including my personal Hotmail account that works fine. I just added an Office365 account from GoDaddy, and it automatically configured and installed. I then logged into the Microsoft 365 with my password and the configuration concluded successfully. I can receive emails but cannot send any. I get error messages shown in the attached images. I've also attached the settings for the account and the smtp settings. They appear to be identical to what is recommended. I need help.

Videos on the NY Times web site never play on my Windows 10 PC, though they do run on my Windows 11 and iPad Firefox. Have disabled all script and ad-blockers without effect. If I click on the Play arrow, I get the circle animation that never ends. Windows FF version 128.0.2 64-bit on both 10 and 11; can't tell what the iPad version is but it works.

Hi!

I couldn't find any decent TB or TB Forums Articels about this.

Instead best instructions seems to be here:

https://kb.uconn.edu/space/IKB/26063831538/Configure+Thunderbird+client+to+use+OAuth+for+IMAP%2F+POP

Especially at the end were it say's:

"Click “Done,” a Microsoft log in window should pop up"

That info is totally mssing in those TB Articels I've found.

And with the help from that page I managed to add one of my MS Account to TB (as IMAP), BUT not as a POP3 account that it has always been set as.

And if I try to add an MS Account as POP3 WITH OAuth2 in TB, this "Microsoft log in window should pop up" never shows at all! And then the account ain't working = TB can't poll for mail.

And I can't find out how to Convert/Change an existing IMAP/OAuth2 MS account to be a POP3/OAuth2 account ?! Is that at all possible?

(And why doesn't TB have a PopUp Windows (as in old Outlook Express and Win Live Mail) for when it polls for mail, so one can see what happens with every account, and then clearly read in that windows IF there were something wrong at any specific account. The TB "Activity Manager" doesn't show these thing, but it should!)

(Also TB should check for new mail in ALL Folders, as in SPAM (GMail), in JUNK (MS), and in TRASH, it could be a Setting for each account (or General) to make TB do that.)

/Thanx!

When I tried to get new messages, Thunderbird responds "Check mail server capabilities" and hangs. The latest new e-mail is dated 3:52 AM this morning and nothing since, although I can see many later e-mails using my web-based mail server.

On our web site we have a page that includes mp3 files, which play okay on Firefox; but on another page on the site with mp3 files, Firefox (including different versions on different computers) produces the error message, No video with supported format and MIME type found." FWIW, other browsers like Safari (Mac), Chrome (Mac and Win), and Edge (Win) all play the problematic files without a hitch.

Is there a fix for this problem that can be attempted by the non-tech types?

I've tried restarting and reinstalling Thunderbird but no change in this blockage since Tuesday. I am running Windows 11 Pro and Thunderbird 128.1.0esr (64-bit). Downloading chunks of email from Comcast and trying to import them doesn't work. Please advise as I am stuck. I will check your answers on Comcast server as I can not read them directly.

Why does Thunderbird create a "deleted messages" folder when there's already a perfectly good Trash folder? How can I get rid of it permanently. I've deleted it, but it reappears. I'd rather keep all my trash in one place.

I use Thunderbird on my iMac Sonoma 14.6 with the M1-Chip I mistyped an adress while writing an E-Mail and sent the Mail. Returned realized the Mistake and corrected the adress. ›ow, every time I want to write a Mail to the recepient I am offered both adresses. I Allready deleted the wrong spelling from my Contacts-App, but still ... I tried "search adress", but there I do find only the correct one.

What can I do to delete the adress I don't want to confuse me any longer? Thank you for your help!

I changed my email password with The Messaging Company but Thunderbird will not recognise the new password when I enter it into Thunderbird. I can access my email through the webmail for the Messaging Company but cannot access emails through Thunderbird
