Firefox Support Forum

My laptop has two GPUs which are the integrated graphics card of the Intel CPU and the graphics card of NVidia. Now I want to use WebRender in Firefox, does it use the integrated graphics card or the NVidia graphics card for rendering?

As shown in the picture, my GPU#1 is active, but the GPU#2 I want to use is not active, how do I make GPU#2 active?

Also: when will WebRender be active?

Hello,

when I try to comment on facebook there is no "Press enter to post" and if after entering a text I press Enter on my keyboard the cursor goes to the line bellow without posting the text inputted. Second, if I want to chat with somebody inside the facebook page, after inputting the text, if I press Enter on my keyboard the text won't show inside the chat, it will just make the cursor to go to the line bellow. On the videos, the active buttons are only play and enable or disable sound. If I want to put sound at 10% is not possible. Also, if I want to unroll is not possible, if I want to go to specific time on the video is not possible. Al the buttons are available but I just can't use them all

Hi,

I'm new to firefox, I'm trying on this new linux based config to change from chrome to firefox, and I've got an error on most of the different website I'm trying to join : "Hmm. We’re having trouble finding that site." For short it's the server not found error, but I can access thoses websites from an other browser.

I'd like to solve this problem, I already tried ipv6 disabling, and dns prefetching enabling from this help page : https://support.mozilla.org/en-US/kb/server-not-found-connection-problem and it still not resolve my problem.

It often resolve alone half an hour after I started firefox, but it is way too long...

Thanks a lot for helping me !

Matthieu

PS : domains I can't access : github, my school website, youtube sometimes...

I keep getting this error code when I try to access amazon.com. This is a new problem, less then 48 hours. I can access amazon with chrome and edge.

Where are the site proprietary ? ;-) Firefox 87.0 (64 bits) in Debian Sid

one of my google accounts, which I have been able to sign in through firefox for years, suddenly started giving me an error message after entering my email address on the google sign in page. I have another google account and I'm able to sign i using firefox just fine. The error message given is:

This browser or app may not be secure. Learn more Try using a different browser. If you’re already using a supported browser, you can refresh your screen and try again to sign in.

I'm using a windows 7 box and Firefox 85.0.2.

I'm able to sign in just fine when I use google chrome. I've cleared cache and data in the browser. I'm not sure what else to try. Any suggestions? Any other information I can provide to help identify the problem?

hi there!

is there a way to open a firefox tab in a new private window? it's something i'm wishing for all the time!

(google posts from many years ago state a way to select this option from the menu, but if it worked it no longer is in the menu.)

my reason for needing this so often is that i have many add-ons that block trackers, ads, etc, which are disabled for my private mode. so if a tab won't load, it would be the easiest way by far to get it to do so!

thanks for any help!

Hello, i set up 2 step verification on my Firefox account (using Authenticator application), but not possible to connect Authenticator app with Firefox account scanning QR code...

I don't know why it happened or what to do. I was on the site quite a few times in the past month with no trouble.

My Firefox forgets that I want to use Windows standardapplication (Acrobat reader) when clickin on a .pdf-file. Firefox wants me to save the file after updates. Does anyone have a solution for this issue?

Hi i would like to know how i can change the font size of my Firefox Menu.

i already change the size of the layout whit "layout.css.devPixelsPerPx" but it didn´t change the font size of the tabs or the menu. i did some research and found the userCrome.css technique to change some fonts sizes. i already change the font size of the address bar, PopMenu and tabs. But when it comes to the Main Menu, and bookmarks the font still in the same size. i also try changing the fonts size on preferences but nothing has been working.

i guess there must be a simple command line to add in the userCrome.css file to fix this but i can find it.

if some of you can help me i will appreciate very much.

i am working on a linux machine. thank you very much

Debugging steps:

   Tried clearing the cache & reloading
   Tried disabling ell extensions+ running browser in Safe Mode.
   Tried several different streams: some streams w/ no customization might fix the problem, but it's not entirely clear to me which streams are "completely" customization-free.
   Tried different browser: Edge does not exhibit this issue

The Problem:

Been noticing this problem in Firefox at https://cytu.be over the last couple of months; this seems to be happening with any stream on the site, ; I don't remember exactly when I started noticing it. This is observed directly on the website, not any third-party site.

Messing with stuff outside of the web player seems to have a tendency to break the web player's volume control, resulting in its volume maxing out and desyncing from the video stream; it almost sounds at times like the audio stream is restarting from the beginning of whatever video is playing, while the video stream continues as normal. I've seen it happen mostly while using a wireless remote + Fliirc to adjust settings (mainly OS volume, brightness, and f.lux settings) but it can also happen from my keyboard, as well as manipulating the web player's volume control too much, and also zooming in/out the webpage too much. Clearing the cache & reloading doesn't work, and neither does disabling all add-ons, or running Firefox in Safe Mode. The only solution I've found so far is to refresh the webpage.

Spoke with site's developer, who remarked that he had not heard of anyone else experiencing this bug, and suggested it must be a Firefox issue; something about how the browser interacts with the OS' audio subsystem is probably causing this bug.

Does not seem to happen in latest version of Edge, for some reason.

Running the latest build of Windows 10 64-Bit Windows 10 64-bit OS Build 19042.928 and Firefox 64-bit 87.0.

When I was voice chatting with my friends, I wanted to screen share a tab in firefox, but I couldn't. It didn't say anything, the only thing I could share was the voice chatting app and my recording software. I was also going to screen share my game so I can show it to my school friends but it didn't show the game I wanted to play. I was also in a tutor and was about to share a tab but there was no tab share option. And yes, i did set permission to share my screen. I don't know how to fix this.
