Firefox Community Forum

At home we have a shared computer with Ubuntu and Firefox as main browser. Each family member has its own Linux user.

We use the functionality of Firefox saving passwords, however we've noticed that these passwords are visible between the Linux users. So, for instance if two of us use the same website, somehow our user/pass get are visible to each other. Is this behavior expected? How can we set FF to make the user/pass visible only to the Linux user who is using it?

Cheers

I recently started to get a"The security sandbox is disable" warning. I have already gone into about:config

my settings:

Content Process Sandbox Level 8 Effective Content Process Sandbox Level 0 (note in about:config this setting is 6?) Win32k Lockdown State for Content Process Win32k Lockdown enabled -- default value is true GPU Process Sandbox Level 1

Firefox ver 145.0.2 (64bit)

Dear support, I have 2 pcs and I need to enter sync password every time I open Firefox - start notebook. It works fine on the second pc and password is remembered. How to solve it? Because I need to write sync password every time, open all cards etc .. OS - win11 pro, Firefox browser versiono 145.0.2 64bit, no 2FA in firefox. Thank you. Mike Hrubjak.

I can complete the sign in and enter my password, and then I get a spinning wheel and can no longer click on the tabs or minimize the window. I have to force close it and it shows as not signed it. I've also tried signing in using my phone and the QR code, same thing. This happens with or without 2FA, I turned it off and the issue persists. Everything else about the browser works completely but I can't sync across devices without the Mozilla login working.

Im using Windows 10 Pro 64 bit on a Asus laptop with 32GB RAM in it and a i9-9980HK @ 2.40GHz. It has a GeForce RTX 2060 graphics card in it with 6GB memory. I use it for work and need to have multiple tabs open at a time as a result. I always have at least 4 tabs and can sometimes get up to around 10. I also have Zoom running as well.

I keep seeing a ton of Firefox processes open when I look at Task Manager. Attached is a screenshot I just took with 7 tabs open. It shows 34 processes in the first clump with more open outside of that one.

I unchecked Use recommended performance settings and checked Use hardware acceleration when available but all that did is lower the amount of RAM being used by 100MB. I have 2 extensions enabled in Firefox, AdBlocker for YouTube and AdBlocker Ultimate. They have never been a problem before. This lag and massive overusage of RAM has only started in the last couple of weeks.

Anyone know why this is happening or how to reduce how much RAM Firefox is using? I like this browser and would have to have to switch to another one. Thanks in advance.

Issue Description: I’m experiencing a problem with fullscreen mode while using YouTube on Firefox on Windows 11 with a dual-monitor setup. When I enter fullscreen, the video does not cover the entire screen. Instead, I can still see parts of the Windows desktop or background around the edges of the display.

This issue only happens on Firefox and only when using fullscreen mode on one of my monitors. I have already checked my display settings, scaling, alignment, and hardware acceleration, but the problem persists.

System Details:

Windows 11

Dual-monitor setup

Browser: Firefox (latest version)

Issue: Fullscreen video shows borders and does not fully cover the screen

Expected Behavior: The fullscreen video should completely fill the selected monitor without showing any part of the Windows desktop.

Please advise on how to resolve this issue.
