Firefox Support Forum

So I've recently shifted from Chrome to Firefox and there's his specific touch pad gesture I set up on windows settings and it acts like media controls, but it seem to be unresponsive. Tried it with Chrome and VLC media player and it worked normally. Tried setting about:config; media.hardwaremediakeys.enabled but its already set to true.

i have made a major mistake trying to manage my bookmarks i need to delete all bookmarks and restore previous settings but every time i try to delete files or restore previous book marks firefox freezes. i have manged to copy bookmarks menu into other bookmarks and then copy other book marks back into bookmarks menu multiple times. have probably set a record for most book marks as i had over 1.3 million. i have managed to delete a lot of folder but i cant do anything with the ones i left without freezing

Hello, i have run Firefox for years on 2 separate computers each with their own data and now I want to sync them. My problem is I don't understand to the 2 different sets of data if I sync. Do the 2 sets 'blend' somehow? Does one set take primacy over the other (if so, how do I control which one it is?) or do I lose everything from both computers and start again? I've been wanting to sync for 12 months but I am so scared of losing information that I keep avoiding doing anything. Thanks Chris

Firefox will not run on my desktop as it says its already running. I have uninstalled Firefox & reinstalled it with a fresh copy from the web but the problem persists. I open Task Manager & see Mozilla Firefox appears to be running: "Mozilla Firefox (3)". I end task which stops Firefox opening further but the same thing happens again when I try to open Firefox.

My PC is running Windows 11 fully updated as at today.

Can anyone suggest a fix?

I'm using openSUSE Tumbleweed and KDE Plasma. Ever since I updated to Plasma 6.1, Firefox crashes constantly when using Wayland. I'm not having this problem if I'm using X11. Crash reports are sent after every crash so I'm sure someone can reference these. When starting Firefox from a console, I got this message after a crash: "[GFX1-]: Wayland protocol error: wp_linux_drm_syncobj_surface_v1#67: error 5: explicit sync is used, but no release point is set"

Will this get fixed with the next Firefox update? Currently using 127.0.

One of the typical configuration in linux is to turn off the user namespaces and/or network namespaces. This is because most of the exploits in linux have been related to namespaces vulnerabilities.

If there is a Firefox ver 127.0.2, running on Linux in which the user namespace is turned off then the following is observed in the Troubleshooting information, i.e. about:support Seccomp-BPF (System Call Filtering) true Seccomp Thread Synchronisation true User Namespaces for privileged processes true User Namespaces false Content Process Sandboxing true Media Plugin Sandboxing true

So how come with the username turned off, the content process and media plugin is still sandboxed? Also is having user namespace turned off, as given above, a security risk?

However if the network namespace is turned off, i.e. max_net_namespaces is set to zero, then it renders the browser unusable. Nothing works. Why is that?

Is there some documentation somewhere where these namespaces and their impact is explained in detail?

Installed 127.0 (20240606181944) from http://download.opensuse.org/repositories/mozilla/openSUSE_Leap_15.5/ and since then I've been unable to:

• Close a window by closing the last tab (the last tab X does nothing)
• The toolbar Account icon has nothing under it, have to go via Settings to manually sync and manage account

OS Version: Windows 11 Home, 23H2 Firefox Version: 127.0.2

I have several virtual desktops: Desktop 1, 2, 3 and 4. Case 1: Assume that there is at least one opening Firefox window in any virtual desktop. And, if I try to open a new window in Desktop x (x = 1, ..., 4), it will appears in Desktop x as expected. Case 2: Assume that there are currently no opening Firefox windows in any virtual desktop. And, if I try to open a new window in Desktop 2 or 3 or 4, it will only appears in Desktop 1.

Hello everyone!!

I've been experiencing a rather "unusual" issue: My Firefox up until version 116.0b8 worked perfectly fine; however, after any updates to versions beyond that, it stopped working.

I've tried the final versions and the betas, but nothing works. I attempted reinstallation and everything else, but I couldn't solve the mystery and remain stuck on version 116.0 beta 8.

What's happening? Every time I try to load a page on any version above 116.0, it either doesn't open or keeps loading in a loop. Yet, if I use another browser or revert to version 116, everything works correctly. This issue does not occurs in others machines.

Has anyone experienced something similar?

Thanks in advance for your help.

Dear FireFox, I am writing this E-mail to address a critical issue. So i wanted to set up a password for my firefox browser so that only I can access it. i set a primary password, and it asks me to enter the password when i open my browser. However, when the message appears asking me to enter the password, you can just click "cancel" option or press 'x' it ignores the password and lets me in the browser, essentially rendering the purpose of the password useless. thus anyone can access my browser. i request you to fix this problem. Regards -SpideyKnight

1. In the past there was a restriction on the suggested number for "network.http.max-persistent-connections-per-server". Is that still the case?

2. Does prefs.js contain all the altered about:config settings? Can I safely transfer "prefs.js" to other profiles in attempt to enable all those settings changes, instead of changing them manually, one by one.

I switched back to release from nightly because the themes support completely broke rendering of menus, buttons, etc on various (read: pretty much every single one, including this one) websites, making them difficult or impossible to use. I've tried a browser refresh to no effect.

unfortunately, it appears the feature has been rolled out to release now as well, as pictured below.

I've tried cycling through themes, setting custom colors and forcing it to never replace the website's specified colors etc, turning off acceleration... none of it works. this is an issue on my desktop, laptop, and tablet (surface pro x), basically every platform I use except mobile.

any ideas how to fix this? it's really annoying and I'd really like to not hop browsers again, I've been using firefox for a good long while now.

For several months, Firefox has been unable to play videos from various different websites, including Netflix, Paramount Plus, Youtube, and others. I've turn off VPNS, reset my internet router countless times, cleared cache/cookies, flushed DNS, updated firefox, updated my video drivers, updated windows, disabled extensions (including adblock), opened Firefox in safemode, and reset hardware acceleration. This is not an issue on chrome or edge. Some of the error messages include: Netflix F7351, Paramount Plus 5000, and error code 102630. Youtube mostly doesn't work on livestreams, and says that my browser isn't compatible.

This started a week or two ago intermittantly on some websites. Today I cannot see any images of amazon items in the shopping cart. I can see the thumbnails in the right side bar, and if I click on an item, the image appears on its for sale page. Ebay usually shows the first image, but the rest won't load, unless I click on "unable to load images" and then they might. Or if I use the icon to put the images in their own box, I can < and > to navigate them

Turned the new "secure DNS" feature off & on, no difference. Turned off NoScript, no difference.
