Hello, sadly I have the problem since a few days that firefox opens a new tab with the same error every time I google something or click on a new page/subpage etc. The URL on the error page is all the time "https://0.0.0.1/" mentention of course a page loading error. I don't know why firefox keeps oppening new tabs with this URL. I allrady tried to use the clearing function and even reinstalled the software, nothing worked. Maybe somebody can help me solving this problem, it is very annoying to have multiple new error-tabs per minute in a normal work flow. Thanks and best regards, Thomas

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 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?

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 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.

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)

Hello, When i create a new tab (cntrl + T) I can no longer just start typing and have that be a google search. Now I need to manually click in the search bar. Is there a way to enable it so creating a new tab automatically puts the text into the search bar field?

Not sure why this stopped working, maybe a recent update. Thanks for your help.

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?

Just updated to the latest firefox version 119, and noticed that the url links are now all underlined again. Checked the support page that says it can be undone in settings, but when I opened up to the said setting page, there's no option to uncheck underline links. Where else can underline links be disabled?

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?

Outlook recently made Edge or Chrome the default browser, with no possibility (as far as I can see) of choosing Firefox. In Outlook FILE/OPTIONS/ADVANCED, it seem impossible to choose Firefox.

How can I make Firefox the default browser. This situation occurred after recent update (October 2023).

Any help would be appreciated. -- JGS

An error occurred during a connection to www.facebook.com. SSL_ERROR_DC_EXPIRED What in the world? does Facebook not keep up with its own security? or is this a Firefox thing?

I removed everything from the bookmarks menu that I don't need. Now there is a battery of separators left, consuming menu space. See attached screenshot of German Firefox version.

How to get rid of at least four of those five separators?

Also, it would be great to have all my bookmarks at the top of the menu, while all that stuff I rarely need (Show bookmark sidebar, More bookmarks, Bookmars symbol bar ...) is at the bottom. Is there an way to change that?

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'.

Hello,

I noticed that a setting on the about:config page was removed: the "security.csp.enable" setting. I was using this setting to disable CSP to be able to load local JS scripts on some non-locally hosted sites, for debugging and development, work related purposes.

Was this setting really removed? Is there a way to disable CSP on Firefox on the latest version?

Thanks! Gabriel.

New computer, running Windows 11, McAfee LiveSafe came with for 30 day trial. I use Firefox, have since 1997. Just added Mozilla VPN. Old computer ran Xubuntu. Windows 11 needs antivirus because it's Windows. So. How compatible are McAfee LiveSafe and Firefox with Mozilla VPN? What suggestion, if any, does Mozilla have for an antivirus program that will work well for Windows 11 but not mess with Firefox and Mozilla VPN? Thank you.

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?

Hello,

I have autofills and login savings disabled, but browser still seems to be saving form data including usernames. How do I disable browser saving any form inputs altogether?
