I have installed Thunderbird and logged in via Google account and I have no problems with receiving e-mails, unfortunately sending out does not work. Somebody told me to choose OAuth2 but this option does not exist for the "sending out" server. My email is on gmail. What to do? Witoldrem

I've just had my browsing interrupted with this recommendation to install an extension: https://torrent-protection.com/download-now/

I was viewing this page: https://www.eurogamer.net/with-the-new-ps-plus-premium-and-extra-sony-opts-for-the-car-boot-sale-approach-to-catalogue-gaming

I was taken out of the page without pressing anything and taken to this recommendation. In particular, it appears like an official Firefox message and security recommendation, with Firefox suggesting I should install this extension for my security. Sadly I don't have a screenshot but it's happened twice this morning already.

Is this really Firefox endorsed? Or are they pushing their extension with fake credentials? How is the page viewing interrupted this way and diverted automatically to another webpage?

Facebook hacked might be coming from Whatsapp that stole ally apps that I can't enter Facebook because I am deaf as hearing imp6 that I need your help to fix this situations please !

Please see the attached screen shot. The icons at the top which allow you to toggle between watchlists are not available, and if you look at the list of stocks, some say "Equalizer" instead of showing the icon. Any settings I need to check?

Thunderbird now uses SQLITE data base files for Address Books. I'd like to copy an address book to another computer for use with Thunderbird there. How does Thunderbird recognize that a given SQLITE file is an address book? Is it solely based upon the file name (to the left of the .SQLITE porition of the name) beginning with the string "abook"? Is there something else in some configuration file that maintains this notion? Are there multiple files associated with a given address book? For example, I see these files in my profile directory: abook.sqlite abook.sqlite-shm abook.sqlite-wal So, I'm guessing the answer to that last question is Yes.

Any help with this would be greatly appreciated!

I don't like the "view panel" in Thunderbird so I always work with it turned off. However, if I restart TB 91.10.0 (32-bit) for any reason the panel always comes back (Win 10 Home) and I have to turn it off again. It never used to do this; instead TB remembered my preference. What am I doing wrong please?

My life partner died a few months ago. They had an IMAP Gmail email (we use Thunderbird as the local client) and there are several emails that I wish to keep that I need as an administrator of the estate. However, I want to delete the Gmail account as I get too much junk mail. So, If I tell Thunderbird to quit checking an IMAP Gmail account, will Thunderbird maintain (keep) all the messuages it currently has downloaded for that account? If so, then I can tell Thunderbird to quit checking the account, then log into Gmail itself and delete the account and because I have told Thunderbird not to check the account, it won't know the account has been deleted. And I also have used Google Takeout to export the Gmail email in MBOX format just as a precaution.

Audio was working fine until recently. Now, firefox has no audio playing on any site.

Some sites show "PLAYING" in tab, but others like YouTube don't show that notification. Even with "PLAYING", there is no audio output.

I checked Windows settings and Firefox is set up correct (and the same as it was before it stopped working), see screenshot attached. Otherwise, I restarted Firefox, tried it in troubleshoot mode, and reinstalled Firefox. No changes.

Possible system changes include: Maybe a Firefox update occured and broke the program? I installed the game Civ5 from Steam which required some Windows VS redistributibles installed.

I have tried all of the suggested solutions here at Mozilla for how to delete a website URL from being autofilled: whenever I type 'pre', the autofill function fills in the rest of the website 'www.preply.com'. It was a horrible ESL teaching scam website, I only taught through it for a month last November then quit when they ripped me off. But now since last November, any time I type in 'pre'–I invariably see their annoying, shitty website :-( It is very annoying because it was a bad employer experience–and now I cannot ever remove them from Firefox :-(

I tried deleting it in the address bar with shift + delete, then also went into some obscure Firefox folder and deleted some file with Firefox closed (this was the supposed "solution"–it did NOT work).

Is there any way to solve this incredibly annoying issue? Or should I just switch to Chrome or Safari and give up? Very disappointed in how impossible Firefox makes deleting autofill URLS, really, REALLY BAD software programming. Any helpful or solution greatly appreciated thx :-)

I have thunderbird 91.10.1everytime it turns on it says cant update click to download something like that. But when I manually check it's up to date, I have reinstalled it but it still does this? It's set to check and auto update what going on and how do I fix this?? Iam running the latest version of Windows 10.

Long time user of Tbird. Currently running it on ArchLinux. I have many email addresses handled individually in Tbird 91.10.0 64bit.

Recently I noticed that new accounts on IMAP don't get the Send /Attach buttons, or anything else on the composition toolbar. The toolbar is visible, at least the bottom 10 pixels of it, unless I uncheck it through ALT V T O, but no buttons. Things I have tried: Everything here: https://appuals.com/send-and-attach-buttons-missing-in-thunderbird/ plus renaming xulstore.json so that it recreated. Attached are screenshots, where you can see window with Comp toolbar visible on a POP account. And one where it is just about a 10px line on a new IMAP account.

I heard recently GMail switched to OAuth. I changed the STMP settings to OAuth for receiving. Now Thunderbird 91.10 can read the emails. However, I cannot change the settings for outgoing because there is no OAuth option there!

Using Mac OS 12.4 and Firefox 101.0.1. After launching Firefox, a second icon appears in the "recently used" apps section of the Mac OS dock (see attached screen shot). The icon stays there and goes away, and then comes back, and then goes away, etc. This continues on and on until Firefox is closed.

Why is this happening? Never acted this way before the latest updates.

As the headline says:

I have got a bunch of spam messages which I am currently investigating for certain reasons. The spammers have set the "Date:" header far in the future (e.g. 2026-01-04), and the "Date" column in the message list as expected shows these weird dates.

However, the "Received" column in the message list as well shows the same weird dates although the topmost "Received:" header in every message is correct.

Here is an excerpt from the header section of one of those messages which shows the "Date:" header and all "Received:" headers (sorry that I couldn't find out how to format the following passage as code):

Date: Thu, 14 Jan 2026 03:38:55 -0800 Received: from deliver ([unix socket]) by morn (Cyrus 3.0.8-Debian-3.0.8-6+deb10u5) with LMTPA; Fri, 05 Mar 2021 12:17:37 +0100 Received: from pop.example.com [a.b.c.d] by morn.dep01.example.com with POP3 (fetchmail-6.4.0.beta4) for <user@localhost> (single-drop); Fri, 05 Mar 2021 12:17:37 +0100 (CET) Received: from server.spammer.com ([e.f.g.h]) by odysseus.example.com (8.15.2/8.15.2/Debian-14~deb10u1) with ESMTP id 125BHDIJ001425 for <user@example.com>; Fri, 5 Mar 2021 12:17:13 +0100 Received: from imap-director-5.dovecot.xion.foo.bar (i.j.k.l) by imap-backend-28.dovecot.xion.foo.bar with LMTP id [an22] (envelope-from <bounces+XmuZjwsANPH/dOCq73______________3@mail.randomcharactershere.com>) for <to>; Thu, 14 Jan 2026 03:38:55 -0800

Please note that there are other headers between the ones shown above. I have removed these other headers. I did not change the order of the headers shown above.

Of course, I am aware that the last "Received:" header causes the problem. But this at once leads to the question how TB chooses the "Received:" header from which it extracts the date / time to display in the "Received" column.

As far as I know, SMTP servers and other software involved in the transportation of messages must put their own "Received:" header (if any) above all other "Received:" headers, so that we can reproduce how the message hopped through the net by reading all "Received:" headers from bottom to top. That is, the "Received:" header which reflects delivery to the IMAP server my MUA is connected to always must be topmost.

TB obviously does the opposite (consider the bottom-most "Received:" header the most recent one, i.e. the one whose date should be displayed in the "Received:" column), or it is trying to be overly smart (sort the "Received:" headers by their date, consider the "Received:" header with the "highest" date to reflect the last hop, and consequently display that "highest" date in the "Received:" column). Both would be wrong.

Could anybody please show me how to get around that situation? Is there an extension which does it right? Is it correct that (according to the SMTP RFCs) each software component must put its "Received:" header (if any) above all other "Received:" headers as the message flows through the net?

Thank you very much in advance!

P.S. As a bonus, could somebody please explain how to format something as code here?
