I have a Snowflake add-on, which requires WebRTC for connections. But WebRTC is not permanently active in my Firefox browser. See image. I activate WebRTC by toggling the config variable media.peerconnection.enabled into 'true' and the add-on works. For some time, only! After a couple of days it is back to 'WebRTC not detected'. What is wrong?

After exporting bookmarks.html from Ffox on old computer, importing it to Ffox on the new one, all good, except that bookmarks toolbar shows on the imported list but doesn't display as toolbar.

I made the mistake to following Mozilla's advice on why my tabs stopped coming back after I closed out, despite the fact that I had that selected in my settings. Now I'm stuck with an "Old Firefox Data" folder on my desktop and I can't remove it because I need administrator privileges -- but it's my personal PC. WTF

I am using Firefox v140.0.1 Snap on Kubuntu 25.04, Kernel 6.14. Since the Firefox update in the past couple days, the mouse cursor has started appearing huge and slightly blurry (as though the image is scaled up) in Firefox and nowhere else. The size is visually annoying, and occasionally difficult to know exactly where I'm clicking (trying to move the caret in a text box for example). It also appears to be a different style from the main desktop cursor, the shape and color are ever so slightly different, but this may already have been the case and I simply didn't notice because of the previously small size. Firefox doesn't have its own built in cursor settings that I can find, nor obey the system cursor settings. I have a high DPI display so perhaps it is being over-compensated for? e.g. both the system and Firefox are scaling the cursor up, assuming the other hasn't done it already, resulting in a cursor that's too big.

To sign into my Amazon account, I'd like to enter only my email address and my password.

But I have to enter my email address and my passkey. A verification code is then sent to my email address. I then need to enter that verification code to complete signing into Amazon.

On the Amazon's Sign in page (where I enter my passkey), it says "This request comes from the app 'firefox.exe' by "Mozilla Corporation".

How do I disable the two-factor (aka two-step) authentication for Amazon in Firefox?

After tinkering with about:config (shouldn't have...) the background of every page that does not specify a body background color turns the color of my theme background color.

Using the firefox color pipette says its white, but it clearly isn't.

The theme i have is dark, making any page that expects the background to be white unreadable (without DevTools -> Body -> background-color: white)

I haven't been able to find the config that fixes it.

Hello all!

According to the article [Firefox Profiles] there is supposed to be a way to manage profiles through the account icon. I do not have that option on my build 140 with windows 11.

I created profiles using the about:profiles command; however, they seem to want to be separate accounts, not profiles.

I want help to achieve the functionality as described in the article so I can stop using Edge because I need to keep my work/personal/school accounts separate.

Thanks!

Hello! I contacted you with a problem with the impossibility of installing two-factor authentication on my account. Despite successfully entering the code and saving backups, two-factor authentication disappears immediately after refreshing the page. Mozilla stores all my passwords and data - therefore, two-factor authentication is very important for my account.

The release notes for Firefox version 140.0.1 indicate the extension button can can now be removed from the toolbar.the noes say:

"Firefox Extensions: Customize your toolbar with the option to remove the extensions shortcut, giving you more control over your browser. When the button is hidden, you can access the extensions panel again at any time from the Firefox menu by clicking the Extensions menu item."

I still cannot drag the button down and out of sight by customising the toolbar.

Suggestions welcome.

Hi there! The New Tab page looks great with white text, but Firefox 140.0.4 thinks my wallpaper is white, so text should be dark. I can change the body class to "activity-stream darkWallpaper" using the inspector and it works fine, but how make this change permanently?

I joined a Microsoft Teams meeting through Firefox on the web on a Linux machine. When I tried to share my entire screen, I was asked if I wanted to share the entire screen in a Firefox pop up which I said yes. Then the "you are sharing your entire screen" came up, the sharing icon was red and the "stop sharing" button was red. See attached image. This all disappeared and reverted to the default state almost instantly.

Teams has a feature to "manage what attendees see manage what attendees see" where the meeting host can preview shared content before making it live.

I am concerned that the meeting owner was able to see my entire shared screen without me even knowing it through this preview.

Can someone help? Microsoft just sends you around in circles and I can't contact Mozilla.

I don't know what you're doing but EVERYTIME I do an update lately, something goes wrong. Today after update, my STGs are affected and ALL ARE GONE. I do NOT believe this is their fault. And you put this dang auto Startpage when launching window, I did NOT ask for that. I am so pissed, how do I get them all back? I had things I was working on that were very important. What else did you add to FF that I don't know about? I don't want your updates anymore. You screwed me big time. And I don't want the extensions YOU think I should have: Google, eBay, Bing, etc. wasting my space. I'm not the only one either, seen lots of complaints.

HOW DO I GET THOSE TABS BACK??????

Hello,

I'm facing an issue where my microphone does not work in Google Meet when using Firefox, even though I’ve granted all necessary permissions. This problem is specific to Firefox, as the microphone works perfectly fine in Google Chrome.

I prefer using Firefox because of its convenient screenshot features, but this microphone issue has caused major inconvenience during important meetings.

Kindly help me resolve this issue.

Thank you.

Today randomly i noticed that my bookmark bar is waaay shorter out of the blue, i didn't change or adjust anything, all i do is the updates from mozilla that's all, it was all music it really saddens me because atm it's lost forever, i hope somebody can help me (i don't know since when it disappered i literally just noticed it right now ...)

I accidentally clicked on a site that was supposed to be a game review site that I found on a Bing search. Now I get pop up ads for fake virus programs whenever I run Firefox.

I ran a scan with Mallware Bytes and Microsoft Defender and both scans came up clean.

I am including a screenshot of the popups.

Any ideas?

Thanks

The app sizes two adjacent images to the same height. Maybe there's a better approach?

This works, in that I see the original image displayed at the wrong size:

   //img.src = imgsrc.src;

This sizes the image but without the data (black square for toDataURL w/ image/jpeg) in FF, but not Chrome and Safari:

   var canvas = document.createElement( 'canvas' );
   canvas.width = width;
   canvas.height = avail_height;
   var context = canvas.getContext( '2d' );

   // Tried/failed: Fill white background for JPEG export
   //context.fillStyle = '#fff';
   //context.fillRect(0, 0, canvas.width, canvas.height);

   context.drawImage( imgsrc, 0, 0, canvas.width, canvas.height);
   context.lineWidth = 150; // ??

   img.src = canvas.toDataURL('image/jpeg', 0.92);
   img.onmousedown = disableDragging; // for FF
   img.style.opacity = "1.0"

The page is the view.html one gets to via Enter on phobrain.com.

After Windows crashed, I installed a new system and logged into Firefox using my account. But all my history, passwords, bookmarks were erased. I also went to my phone and everything was gone. I didn't erase anything myself. Is there any way to restore the previous state of the account? Are there any backups on the Firefox Sync server?
