Firefox Support Forum

I am getting notifications with the Mozilla logo or sometimes with McAfee logo saying "5 Viruses found, your computer is unstable" and various other warnings. They all also say "via qltuh.titanicooler.top" I have attached a picture.

I have closed the browser, I tried clearing my cache, I have scanned using both AVG, AVAST, F-Secure Online Scanner, and Microsoft Safet Scanner. I am not quite sure what else I should do.

Thank You

I have a very good PC (5800X3D, 7900XT, 32GB DDR4 3600), but Firefox (either the normal, canary and nightly version) can't play smoothly any 4K video (like the Borderlands trailer: https://www.youtube.com/watch?v=lU_NKNZljoQ ). 1440 and lower resolutions are fine, as are 4K videos on Chrome and Edge. FWIW, my CPU during 4K playback is barely used (1-2%), and my GPU's video codec (VCE) is used by around a third. Disabling HW accel makes things better, as it still stutters but it's (barely) passable. I already tried creating a new profile, but still it's the same.

I have a slight problem. I'm currently using Firefox 116.0.3 and it seems that it can't update. The automatic updating will run, and then it will fail (this is all the time when using Firefox). It will recommend me to download the newest version from the website, but then the CDN will and I will be presented with the "connection was reset" error. This happens both on my Windows 10 and Windows 11 machines. Both are running Firefox 116.0.3.

Funnily enough I tried to see if I could download the newest version on Edge (Chromium), which it could but the version I got from the website was the same version I have now. I wonder if this is something to do with my region as I'm based in China and I'm aware that some software can have...problems.

Also, when trying to download version 122.0, it is fantastically slow and will often fail to complete.

Is there anything that could be suggested as I really don't want to use Edge.

Hey, so, I've seen this question a couple times when I searched, but (a) there didn't seem to be any solution and (b) they were all regarding Macs and I'm on Windows 11 v 23H2. I keep getting bubbles saying that Firefox wasn't able to check for updates- not that it couldn't download or install updates, but it couldn't search for one. I also did the "about Firefox" thing and it gives me the same message. Both of these have been going on for a couple days and I have attempted restarting Firefox multiple times and did a manual update [125.0.1 (64-bit)] just in case there was a problem there. Now, I've tried the tips from the other threads (turning off the proxy, checking any anti-update policies, and checking the add.update.url in the config settings) with no luck. So in an effort to either bump the question or get any Windows oriented answers... Thanks muchly

I have been experiencing a problem with Cloudflare specifically on one site (character.ai) and when the verify you are human pops up. It takes me in a seemingly infinite loop. On the Cloudflare community site they say it could be because of things like adblock but even without any adblock or anything of the sort on it does the same thing. Sadly Cloudflare community doesn't support being used on Firefox. So maybe they don't support being used on Firefox in general? I have contacted the actual websites support but they don't seem to even read submitted inquiries because I never hear anything back from them except the automated message they received it. It is now preventing me from using certain things in general which as before it wasn't that big of a deal but recently they changed the site layout and still allowed you to use the old layout but the verification blocks you from using the old layout. The first one is one from a couple of weeks ago when it only effected me trying to open things in a separate tab and the second one is the newer one which prevents me from accessing the old layout. I'm not sure what to do about it since nothing I specifically could do to solve it has helped. I have opted into sharing data under troubleshooting IDK how well that'll help.

Hi, Please advise how to remove, disable, delete, block the new added "Your browser is being managed by your organization." to my Settings page. I'm home user .Also Please know that this is generating "FALSE FINGERPRINT CERTIFICATES" thank you

Every time I am trying to search, google is always pinned on my search bar, and I want to get rid of it. How can I remove google? (On the image I marked the issue with a red circle)

I recently updated to 125.0.1 and now get 'failed to check for updates': - when I manually check (help > about Firefox) (see image) - in 'settings' it also shows 'failed to check for updates' (see image) I never had such a problem with previous versions; any suggestions?

I've read all the suggestions but can't get Firefox Sync to transfer the open tabs from my old PC to my new one. I'm signed in on both to the same account, both are on my LAN with a wired ethernet connection, and I've checked every box in the "what to sync" field. When I click "Sync Now" the icon spins for a few seconds like it's doing something but the tabs from the old machine do not appear on the new one as I expected them to. Nor can I get them by closing and doing a Restore Session.

This seems pretty straightforward and how most users would expect it to work - am I missing something? If not, why isn't it working?

As of today, I am unable to scroll with my mouse in google sheets. The scroll bar on the right disappears and I'm taken to the bottom of the spreadsheet and can't scroll back up. I have to use CTRL+Home and then the arrow keys to go down the rows. This appears to be only on Firefox. I tried a different browser and it worked fine.

I have just upgraded to Firefox version 123. Now whenever I start Firefox on any of my profiles, it will immediately or almost immediately display a "Welcome back" popup stating that "Here’s a quick reminder that you can keep your favorite indie browser just one click away." and provides a button to make the browser the default one. That's exceedingly annoying - I can understand that Firefox wants to notify my once in a while, but this happens at least once a day, probably more often than that. I looked over the source code and got that it is a "spotlight" feature, but I failed to find any settings that would turn it off. Any idea how can I disable this forever?

Using the arm64 version of Firefox on a Surface Pro X causes several graphical issues. These issues started either with a update of Firefox or drivers.

This topic has already been reported, please see here for more information and documentation: Reddit: https://www.reddit.com/r/firefox/comments/182iojx/firefox_arm64_graphical_problems_on_surface_pro_x/ Mozilla Connect: https://connect.mozilla.org/t5/discussions/firefox-arm64-graphical-problems-on-surface-pro-x/m-p/52086

What can be done to report this issue and help it getting fixed?

There used to be an extension called "IE Tab". It allowed you to right click on the link, and open the site in a tab, using Internet Explorer, for sites that didn't work properly in Firefox. I was wondering if anybody knows of any similar extension that would do the same for Edge? I can't open Twitter (X) using Firefox anymore, but I can open it using Edge. I don't like Edge (obviously), but I have no choice. Thanks in advance!!!

When switched to mobile hot spot from wifi [and viceversa] Firefox can't load websites but other browsers can. I am facing this issue recently like from a month or so. Before that all working fine. I have already tried the troubleshooting steps from here https://support.mozilla.org/en-US/kb/firefox-cant-load-websites-other-browsers-can, Still no luck! Edition Windows 11 Home Single Language Version 22H2 OS build 22621.2506

Note:Whenever i switch to mobile hot spot i have to restart laptop to make Firefox work.

Is there any permanent solution for this problem?

I have been watching SBS OnDemand successfully until today. I now receive a consistent Video Playback error on any video using Firefox Ver 124.0.1.  I do not have an Adblocker installed. (Windows 11 Pro 23H2).  I do have AVG Internet Security installed.  I installed no apps. I turned off Enhanced Protection for sbs.com.au in Firefox but the problem persists. The problem does not occur on Chrome.

I had been using Firefox browser for awhile, but because of playback performance issue, I have to using another browser just for video playing, especially for 4K video.

Compared to Edge, Firefox seems taking more resources to playback the YouTube video and more heat. When look at the Task Manager, the Video Processing is 0%, and GPU is running significantly more resources on '3D'.

Thanks for last message you sent via "no-repy".

You ask me questions in those e-mails, but I can't reply.

The last had a lot of if you are running this ..... then this ....

I'm not using Windows XP or Vista!!!

I keep my software up to date.

Well, I guess I have to part from Mozilla. For a long while it was so good, but lately ...

Hello. Since I use the bookmark bar and fullscreen mode a lot, I would like to be able to see the bookmark bar in fullscreen, not on every tab, but only in a new (empty) tab, so that I can avoid disabling fullscreen to access the bookmark bar and at the same time not having any part of the interface visible unless I'm in a new tab. Thanks in advance for any reply!

More and more I'm having to go to other browsers like Chrome or Edge to open certain websites as they do not work through the Firefox browser. Why is this and how can i get them to work before i change browsers permanently?

Since the update that changed the cookie management, I have not been able to delete just my cache without losing all my cookies & login information. I'm no longer able to automatically sign into a bunch of my sites.
