Diễn đàn hỗ trợ Firefox

I just bought new PC and switched to win11(never happened on win10). Videos stutter when on 2nd monitor and game is open on first, but audio doesn't. Problem goes away immediately when clicking to the firefox window. Happens on both youtube and twitch, but not on Nebula.tv and not on chrome. Doesn't happen if the video is 480p, but does on 720 and 1080 and both of them are 60fps which might be something. Also doesn't happen if the game is windowed, but does on fullscreen and borderless.

I've disabled hardware acceleration (in windows and browser). I've tried setting both monitors to 60hz, setting firefox priority to high (and game to low), disabling effiency mode, setting power mode to performance and tried a lot of other things including about:config settings. Also ruled out extensions.

CPU: AMD Ryzen 7 9700X GPU: RTX5070 1st monitor: 180hz 2nd: 80hz

I downloaded firefox desktop for my imac 27" none of the passwords I had on file would work so I changed the password and tried it. It appeared to work but after a while the incorrect password came up again. I continued to try using the code you sent via email several times and even though it appeared to. accept the password it still rejects your code. I have tried both caps and lower case characters but it still rejects the login

Hello,

I’m reaching out because I’ve been experiencing persistent loading delays on Firefox across all websites. Pages eventually load, but it consistently takes longer than it should or don't load at all, can't even log in on some sites such as Twitch. At first, I thought the issue was only on YouTube, but I’ve confirmed it affects all websites.

I’ve already gone through extensive troubleshooting steps, including: Clearing cookies and cache Changing DNS providers (tried both Cloudflare and Google DNS) Using the Firefox Refresh option Fully reinstalling Firefox Scanning my system for malware (none detected) Verifying that no extensions or add-ons are installed Confirming my internet connection and speed are stable Testing the same sites in Chrome, where everything loads smoothly Despite all of this, the problem persists only in Firefox. Thank you in advance for your support!

When I use Gemini 3 visual layout function to generate a homepage-like page, but Firefox cannot show any content of the result. It works fine in Microsoft Edge and Google Chrome.

After a Windows 11 update, Firefox does not automatically start although set to do it and when I start it, a small rectangular box appears in the upper left corner of the screen.

Please resolve.

My bookmark features has stopped working. When I click the star, it does not turn blue and I cannot bookmark anything. Is there a fix? I have stuff in the bookmark area and would not like to loose it.

Hello! I have a problem with GeForce NOW in Firefox. When I launch any game, the cursor freezes and does not move inside the streaming window. Outside the GeForce NOW window the cursor works normally.

Details: - Only happens in Firefox - Other browsers work fine - Cursor gets stuck right after entering a game - OS: Linux (Arch)

Is there any fix for this? Maybe it's related to pointer lock or hardware acceleration settings?

Using latest Firefox browser, when I open Google and want to ‘paste’ a word, it will not let me. Instead I get this default message, that I can’t delete. I can type anything I want, but I can’t ‘paste’ a word or words. How to fix please? HP desktop PC Windows 11 64 bit I see there is a 'new' (to me) AI mode icon in the 'same' search window as where you type on the 'right' of the search box. Maybe I just haven't noticed because I didn't have an issue before.

Thanks in advance for any suggestions

why is it a web site accessed couple days ago, now times out trying to re-access it another day?

i called the web place in question and their system is up.

thank you

Just a week or so ago I could no longer login to Vanguard using firefox unless private version was used. THis happens on any product where firefox is default browser-Windows, Android and MAC all give a login/password error and nothing shown in the previous fixes work. Cache, troubleshoot mode, extensions and the other stuff have no effect on access. I can use Chrome and edge (both of which I hate) with no problem.

My desktop icon has disappeared. It is still on the taskbar and in Start Menu (Windows10), also listed in programs on control panel. However I can not find it in Program files and have not been able to reinstall the desktop icon. Can you help me? Leslie Booth ([edited email from public support forum])

I'm in Troubleshoot mode, no extensions running, and tabs are crashing again. Here are crash report #s for today:

Is it coincidence that this is happening on my Windows 10 machine since MS support for Win10 officially stopped? Gosh, I just don't know! grar grar grar

Good day, I'm trying to use my TAB key on my keyboard to move to the next input but instead it only functions as an Enter key now. Which means I physically need to use my mouse to click on the next input field in order to move to the next section. Such a small and basic function that is now gone- and unfortunately a deal breaker for me using Firefox. I need to work fast, working through thousands of lines of data, I cannot sit and click on every field. None of the fixes I've found works.

Bank Login (a single bank) - This has worked fine for years but now there is a problem. I use FireFox password manager and it contains the user name and password and they are correct. When logging in the user name and password are shown and they are correct but the website says user name or password is incorrect. When I type in the user name it works. Why?

Since updating to last version, when trying to access my two banking accounts, on different banks, the send button, when entering my user and password, doesn't do anyting. All other buttons and links respond.
