Recent issue, April 2024. Had version 124 Firefox on Win10 computer and went to Help - > About to have Firefox check for updates. This has worked just fine up until now. The message "Failed to check for updates." is shown in the About screen. I have uninstalled and re-installed Firefox with the same results. Have also un-installed Firefox, un-installed Mozilla Maintenance, then removed Firefox data from App Data folder in user directory, then re-installed with the same results. Also, now when I access a local media server, I keep getting the message "Firefox is installing components needed" and that never goes away. Any ideas?

Hi! On the latest version Mozilla Firefox 125.0.1 when i download .docx files i get the message 'File not downloaded: Potential security risk.' I select Allow download and the file downloaded can't be opened.

Thanks!

Why can't Firefox copy text to the clipboard anymore? It won't copy text from a web page, from a URL, or even from about:support "Copy text to clipboard"!!! I'm using version 1.22 64 bit on windows 11. I've reinstalled Firefox but it doesn't make a difference. I've tried "Troubleshoot Mode" and it's still broken!!!

I can paste into Firefox but something has broken copy!

You have made it IMPOSSIBLE to remove the GOOGLE search engine, by graying out the "Remove" button when the "GOOGLE" search engine is highlighted in the "Search Shortcuts" of the "Search" page of "Settings"!!! THIS IS UNACCEPTABLE!!!!!!!!!!!! IF YOU REFUSE TO FIX THIS, THEN TELL ME HOW TO INSTALL LAST YEAR'S EDITION OF FIREFOX!!!!!

I'm a game developer working on my first WebGL game from Unity. For the past day I've been banging my head around getting controllers to work, only to discover the issue is with Firefox - my build works fine in Edge and Chrome.

What's the situation with Firefox WebGL support? Is this likely to be fixed at any point or should I inform users Firefox doesn't work (and be pressured onto using Chrome or something else myself despite wanting to use Firefox?)

I'm trying to configure my router and the instructions tell me to go to https://192.168.1.1. But the security settings will not allow me to get to that (local network) IP address, and ther.is no option to bypass the warning

When trying to open my protected browser with firefox I keep getting "Firefox is already running, but is not responding. The old Firefox process must be closed to open a new window." I have refreshed and re-installed Twice! I have followed the instructions to go to file (using %APPDATA%\Mozilla\Firefox\Profiles\) and make sure it is NOT Read-Only and to delete the parent.lock in it. Yet it keeps going to Read-Only and the parent.lock keeps re-appearing. The day before everything was working. I have tried Protective Browser with other browsers and it works. 1. Why is the Protective Browser not working? 2. Why is the File going to Read-Only and 3. Why is the parent.lock keep returning? Thanks

All of a sudden I can't open a certain website. I opened the website a few days ago with no problem and have been using the site for years. (I checked to see if the site is down but it's not.) I googled how to unblock websites in Firefox and nothing I've tried works. I disabled Trackers for the website and I cleared my Cookies. I added the Firefox uBlock extension a few weeks ago to stop constant website popups (after I tried resetting Firefox) and I turned uBlock off for this certain website but I still can't access the website. I also installed Mozilla VPN last week. I'm using Firefox 122.0.1. What could be the problem?

How do I paste in the game forge of empires thread windows with my mouse and without clipboard keyboard options in firefox, it will only allow me to use clipboard control V for keyboard not my mouse, using my mouse to select all, copy, it's fine, cannot use paste with mouse, only in browser search bar, i do a lot of pasteing or i would not ask, it works with a diff browser, Firefox is the best for gameing,

I often see a Shortcut on my New Tab that I have never gone to, which says "sponsored" on it. I do not want these ads. I have looked up the answer: https://support.mozilla.org/en-US/kb/sponsor-privacy?as=u&utm_source=inproduct I can manually delete a sponsored shortcut once, but this does not stop them from coming onto future New Tabs. My problem is, the long-term answer simply does not work. Settings -> Home -> Firefox Home Content simply does not contain a section that says "Sponsored shortcuts" and therefore this solution is not accessable. I am on Version 120 as suggested. What is going wrong? How do I prevent these ads from appearing on the New Tab page?

So I just picked up a new laptop (ASUS Vivobook 16x), and everything is fresh on it. Additionally, this only affects some video content in Firefox, with Edge browser unaffected. In brief, what is happening is that within a couple hours of having the browser open, certain video content stops working, specifically Twitter/X videos just spin, YouTube previews stop working, and videos continually load. Netflix videos continue to work, but hover previews stop functioning. I even check the 'Stats for Nerds' on YT and it shows 0 KB network activity in Firefox.

I've tried every basic action I can think of:

• Turning off extensions (only use Ublock and Bitwarden)
• Browser Refresh (x3)
• Reverting from 120.1 to 120.0, and now 199.0.1
• Clearing the browser cache
• Reinstalling NVidia and Intel Drivers
• Running in Safe Mode

Only by doing a refresh or completely closing/opening the app gets videos to function again. This doesn't affect the old laptop or my desktop, which makes me think it's a rogue driver--but then why would Edge function without error over the same period of time?

Are there any settings to play with in the browser that can help diagnose?

In the recent update to Mozilla, all of my shortcuts disappeared. I had many, and can`t remember them all. Is there any way to restore my shortcuts from what they were a month ago? If not, I will switch to Edge.
