I recently have gotten a message about manually updating Firefox on my Windows 11 system. Even after I updated, I then I started getting the same message and also "Failed to check for updates" in the Firefox "about" box and settings page.

I even went about uninstalling Firefox and reinstalling it while deleting the Firefox Program Files and user AppData directories. I also checked for a Windows Firewall entry for the program.

Is there something in another directory or registry setting I need to delete or change? Or does Firefox use a different program for updating that needs a firewall rule?

Thanks for any help.

AVG has ended Online Security Add on for Firefox and AVG has told me that I may not be secure when I use Firefox. How can I stay secure on Firefox. I do not want to have to use any other browser.

I basically hate exclamation marks. I want to hide them. They are mainly in ads, in pages contents, everywhere. Buy! Do! Now! It is most disturbing character and it should be forbidden in non-meaningful manners. Years ago I saw such extension but I lost it due to many Firefox updates, which disabled some of them.

Some stupid admakers go wild and put it in end of every button and line.

Please help

Sir, my hp desktop PC is having -- windows10, Firefox, connect cable Broadband with 100mbps speed, Ethernet, periodically updated. I am very much fond of watching English/Foreign language movies having English CC/Subtitles, online streaming, generally on paid channels e.g. Netflix, prime video, Hotstar, you tube etc. I am not proficient in English language. To read the English CC/subtitles, I have to pause the streaming, read the subtitle and then start the streaming (pause-start, pause-start). After about 15 minutes watching the film, the screen becomes black (no video), with a no signal detected message. But audio/sound remains continue. Then I switch off the PC, restart it, and watch the movie for next 15 minutes., then again black screen.This cycle goes on. But When I watch the film continuously, without pause-start function, then there is no black screen problem. In my opinion this repeated pause-start function causes the black screen problem. Without pause-start function, I cannot watch these movies. I tried some online mentioned solutions without success. Please help me in solving this problem in a simple way as I am not perfect in computer science. Regards.

I'm experiencing an issue, when I visit this website in Firefox, some images appear broken, but they display perfectly in other browsers. Has anyone else encountered this problem or have any suggestions on how to fix it?

Once again Firefox has decided to take over and change all my settings! I had finally managed to prevent it updating, as each and every time I had to reinstall all my setting and extentions from scratch. Today, it decided to clear all my preferences and change itself to its own default settings. OK, so I can change my profile option, except all three are using the same defaults: I appear to have lost all my settings and extensions entirely. OK, I'll copy from my backup, but once again the three backup profiles are being overwritten with the defaults. Even my third backup of last March overwrites to the defaults! How and why is Firefox managing to keep overwriting my defaults to its own preferred settings? How do I stop it doing this and regain my own preferences?

I also tried Sync and now I am getting bookmarks from over five years ago! And once again my settings are changing to the defaults. Surely a Sync should overwrite with the current bookmarks and settings not just keep adding more and more. I am now in a right mess again. Back to losing everything with updates. I am a great believer in the 'if it ain't broke don't fix it' mentality, but Firefox has broken itself and is refusing to allow me to change to how it used to be! How do I restore my own preferences and prevent Firefox from changing them to what it wants.

Thunderbird seems to be hung up in a circular reference. It continues to download 1 of 2 and 2 of 2 repetitively, nonstop. This is continues process without ceasing. It seems be slowing do the whole system.

this interface uses pop3

When emails are pulled, I can see that it pulls, let's say, 50 messages, the notification shows 25 new messages but the inbox only shows 10. I have looked everywhere for the "missing messages" but don't see them anywhere. I have also had some people tell me that they sent an email response (so they were not entering the email address) and I don't see it.

What could cause these differences?

Sorry to have this same issue again, knowing full well it can happen after finding this some years ago (https://support.mozilla.org/en-US/questions/1319823), I tried to carefully connect two older PC devices back to firefox sync, however on one I managed to enable sync before disconnecting my profile (it seemed as if reconnecting sync temporarily was the only way to disconnect a profile from firefox's UI - I should have been more careful and removed the profile from the filesystem level): at which point I polluted the sync server.

I've noticed that `about:sync` has an option under bookmarks/engine actions 'wipe bookmarks', which sounds exactly what I need, and if I watch what happens once pressed it does the right thing and repopulates the sever with the 'correct' PC's bookmark set (when run from that PC), however it also says 'other devices will act like a reset', which i'm finding NOT to be the case: eventually one of my other device repollutes the server with bad bookmarks which propogate.

I'm thinking the culprits are my phones, If I wipe and do a sync on a phone, my phone's bookmarks stay polluted. If i'm right about that, I think my question is: can I wipe my profile (or preferably only my bookmarks) from my phones' Firefox without having to entirely uninstall/reinstall (or do you have any other advice for not re-polluting the server from some already-polluted device's bookmarks?

thanks in advance

Prior to about a month ago, downloading worked as expected: - click a link - the save to... dialog opened - choose the folder - the download is off and running

No more. For about the past month - click a link - wait for a long time with FF frozen - the a wheel starts rotating - after a full minute (or more) the save dialog appears.

Something has been broken in the mad-dash to push updates. It's fine for browsing, but the, you need to download. At that point you wish you were using a different browser (any other browser, in fact) since FF is the only oe that has this problem. Downloading works fine in a 8 chromium browsers that I have and in the 5 FF clones (like Waterfox)

It's just FF that's broken. I can no longer afford to set it as default because of this. The others are not perfect (WF won't activate Pocket, foe example) but downloading promptly is critical.

I am setting up a new Windows 11 Computer and am trying to install Thunderbird. I have downloaded TB (Thunderbird Setup 115.10.2) to my Download Folder. I double click on that file to run the Setup program, complete the user account information and TB and select Continue. TB completes the search and displays the correct account (att.net) connection information, SMP, POP3, Ports, etc. I select DONE and the Checking Password box displays. It runs for a few minutes and an Error message displays: "Unable to log in at server. Probably wrong configuration, user name or password." If I select Configure Manually, a window displays showing the correct configuration information (I have checked it four times). I will note that "Normal Password" has been selected for Authentication Method in case that is important. I have tried this method several times and get the same Error message. Any help will be greatly appreciated. Thank you.

I have attached a screenshot of the configuration window. Note: My account is with att.net but I am still using my old pacbell.net account that was merged with ATT many years ago.

I attempt to open Thunderbird in an iMac but the computer says it is already open and only one can be open at a time. I can not find a Thunderbird open on the computer.

When accessing my site (in attachment to avoid indexing), Firefox blocks with a "Possible security risk" interstitial. DoH requests to the configured https://dns.google/dns-query service work from an external application on the same machine as the browser, but about:networking#dnslookuptool reports the host being unknown.

My email server changed recently from one IMAP server to another. Since the change, Thunderbird keeps marking some messages as Unread. Often these are old messages, reveived weeks or months ago and definitely have been read. The process appears to be random: I laboriously work through multiple folders, marking them as Folder Read. Only to find, next time I open Thunderbird, that there is a new set of messages and folders flagged as Unread. In Settings I have 'Automatically mark messages as read - Immediately on display' checked, which is the desired and normal behaviour. I'm stumped!

Hello, How can we disable QUIC with the latest ADMX or via registry entry on Windows 10. I see not settings under ADMX that can assist in doing so. I dont mind implementing a registry entry in GPO as well.

Thanks

Dear all, I would like to know how to disable the automatic insertion of the tag
in a text editor in Firefox. I am using Froala, and I am experiencing this only in firefox. Chrome and Edge do not add this tag automatically. Thank you for you support. Kind regards, Cristiano
