Is this a bug or config problem?

Occasionally, FF (Linux desktop) starts using a lot of memory. I kill tabs (sometimes it is OK to kill YouTube or X, sometimes not)

Eventually it starts impacting the system using so much memory. I terminate the FF instance. Often. More often than not. There is a separate task still running and I get the "Firefox is still running" when I try to restart. I then kill the remaining FF task via the OS or the process monitor. Then FF restarts.

Is this an issue with addons (I am running very few - uBlock Orign, and Privacy Badger and Cookie AutoDelete. Are the only ones active most of the time) Or is it an actual bug with garbage collection, and tasks getting away? Or is it an OS issue?

I'm putting off upgrading Linux as I have many hundreds of undocumented addons which will be lost and would take forever to attempt to remember how to re-install.

(in fact I might just switch to macos and try using homebrew).

It seems very harsh that upgrading Firefox has been prevented by linux mint for years now.

Yes Homebrew is perhaps the way forward! Life would be easier with just one O/S as I need Macos anyway for adobe lightroom.

It says on https://support.mozilla.org/en-US/kb/about-picture-picture-firefox#w_keyboard-shortcuts that the hotkey to toggle `PiP is CTRL Shift ]`. When I play a video it shows the PiP button, but the hotkey doesn't work. The other PiP keys like seeking and volume work. I'm on Fedora 41 with KDE 6.3.3 & Wayland.

Is there a way to just paste a file with path for uploading. In the windows dialogue I can do that to bypass waiting, but in the linux dialogue 1. I really have to wait for all folder content to be shown (I just tried that on a network drive with a quarter million images) 2. I cannot just type paths that are hidden but I know they exist

Was prompted for various system updates including apps(Firefox). Performance has been very sluggish. At some points, it feels like I'm browsing on dialup. I have a 1GB connection from my ISP.

Not sure if this is a Firefox issue or in conjunction with the other system updates.

After updating FF to v. 136.0 in Linux Mint 22.04, I noticed a problem with video playback in Facebook in some posts. A black screen appears with the message "Sorry, there were problems playing this video". The problem also occurs after disabling all plugins and deleting the user.js file from the profile. The problem does not occur after starting firefox in troubleshoot mode, but then hardware acceleration using the GPU does not work (Compositing: WebRender (Software)). I noticed that in version 136 there were some significant changes in the topic of video decoding. https://www.phoronix.com/forums/forum/software/desktop-linux/1524008-firefox-136-beta-finally-enables-hardware-video-decoding-for-amd-gpus-on-linux-by-default I have an NVIDIA GT1030 GPU with 2 MB VRAM.

installed mint 22 and my sound does not work, in you tube see videos good but no sound i think its a driver issue, but i am new to linux trying to fix. any help is good.

I just set up a server with linux Ubuntu 24.04 Desktop, with Firefox 129.0.2 included to do some dev and testing work.

Problem: Firefox seems unable to see or open files that are above or outside the user's home dir tree.

The only extra packages installed are the LAMP stack and Google Chrome, which has no problem. (had to have something for A/B testing.)

I've tried entering the url of file:///var/www/index.html, I've tried selecting 'open with...' from the files app, etc. Nothing works.

I can get to the file through http://localserver/index.html with no issues. I've verified permissions on the entire directory tree to the file. Everything from end to end has read permissions for all, 755.

I've checked the following advanced settings: security.sandbox.content.level..............................0 (started at 4, now at 0, no effect or change.) security.fileuri.strict_origin_policy.........................false (default setting as installed.)

I am able to open file:/// and get a dir listing. BUT, if I click on var, it gives "Access to the file was denied." I even tried changing the permissions on /var to 777, but no change.

This seems to be a Firefox only problem, since Google Chrome works where firefox doesn't.

I've spent several hours searching for ways to fix this, all with no success. Does anyone have any idea how to fix this, or even what to look at???

Hello,

I'm trying to update to firefox version 133.0. My O.S. is Ubuntu 20.04. I've untarred the tarball to ~/firefox/firefox-133.0/.

If I startup the new firefox, I receive the following error message: "libxul.so, undefined symbol: gdk_window_show_menu".

I also tried firefox version 120.0, except the result was the same.

How can I fix this?

thanks.

Ubuntu 22 LTS, Firefox 131.0.3 (64-bit). My machine crashed last night, but when I booted it this morning to start figuring out what's wrong all my windows/tabs came up. (I have at least 6 windows (for organization of my) hundreds of tabs.) After 6 or so reboots (testing various usb device plug-in configurations) I'm finally done, but now only have 1 blank firefox window. I created an account for syncing so I wouldn't have to redo all that when I upgrade OS periodically; however, I didn't think this would happen, so I didn't sync before this.

I would REALLY like to get my windows/tabs back in the configuration they were. Under 'manage history' there's an import/backup option, with restore; under that, it shows Yesterdays Date with 563 items, but clicking on 'restore' for that tells me it will replace my bookmarks file...

And I don't know how to retrieve the previously synced data, having only used it in the (presumed) other direction.

Any clues welcome!

Hello everyone, i have Linux/Ubuntu software with Firefox browser and for 5 months it has not asked me to update, with it's pop up message. Now it is urgently asking me to update, i have followed the directions given in order to download the latest Firefox version as instructed but with no success. I am downloading it, but it doesn't have an instruction to "run" it. As a consequence, my system is getting slower and slower and i am afraid it will crush! Any ideas? Sooooos!!!

i am having problems to install firefox 135.0 on linux mint 19.3 and if can get instructions that work looked on internet i havent found help there is there a sure fire way to solve this problem ?

I'm using Linux Mint cinnamon 22 and have the latest version of Firefox installed or updated from the app updates. Firefox was already installed and is my preferred browser. But i have the problem when i go to the settings page i see a message on top (picture attached with this post) that says "Your browser is manged by your organization".

Which is simply not true. This is my personal laptop and it belongs to me. I see an answer from Linux mint devs that they will take it up with Mozilla. But that was three years ago. Can this message be ignored or is it still the case? For peace of mind, how do i verify that something is not managing my device?
