Firefox Community Forum

I use Firefox with DuckDuckGo on Ubuntu 24.04, Gnome desktop. My Firefox browser window regularly freezes but can be unfrozen by simply repositioning the window. This is really annoying.

I also use Chromium on the same system and there are no issues.

Any ideas?

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?

Here are the dpkg/apt logs for update:

2025-03-19 12:33:16 configure firefox:amd64 136.0.2~build1 <none> 2025-03-19 12:33:16 status unpacked firefox:amd64 136.0.2~build1 2025-03-19 12:33:16 status half-configured firefox:amd64 136.0.2~build1 2025-03-19 12:33:16 status installed firefox:amd64 136.0.2~build1

The problem is that when I tried opening gmail in my ubuntu, it is stuck at loading page, but other browsers like edge can open it without any problem (on the same system).

I tried every thing I can in the support forum of gmail/mozilla/others, but it's still stuck at loading.

That's all.

snap version seems to have problem thought this might help. I am a software developer.

If I display (e.g.) Nepal in Google maps, initially the Nepali names appear beneath the Latin alphabet names, but only for a split second. They are then overwritten with unicode block icons. Some scripts work (e.g. Cyrillic, Chinese, Japanese, Armenian), but most south Asian scripts do this weird "works for a split second" rendering.

I'm running 128.8.0esr (64-bit) on Debian 12.

This problem does NOT occur in Safe Mode!

In Normal mode, I disabled all plugins and extensions, but the rendering still breaks.

Any ideas?

The same page renders properly in Chrome 134.0.6998.88

I updated firefox just yesterday or earlier today idk and the right click menu is so long with multiples of the same and they DO NoThInG! Linux Mint 22 Cin. 6.8.0-55 Generic Kernel

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

After the last Linux upgrade to 36.0.2 the password or user name hot links only work once. The first time the link is gray and will activate. The second time I try and use this feature the link is not gray and will not activate.

Every time this happens I have to close Firefox and reopen it. Then I get one more shot at auto loading a password before it stops working.

I access google drive through Mozilla Firefox and also zip file or other file download but since 1 to 2 weeks i faced issue to download files especially js file.How can I solve this?

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.

I was trying to go to ssa.gov, today, and hit the button to login. When I did that, I got a 400 page saying: Bad Request

Your browser sent a request that this server could not understand. Size of a request header field exceeds server limit.

I have done this before, and it worked. To test if it was a problem with the web page or the browser, I did it from another browser (Brave), and it loaded fine. Is Firefox sending a bad request? Is this something you can fix.

I am using Mozilla Firefox for Linux Mint 137.0.1 (64 bit).

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?
