Hi, after upgrade of ubuntu to 24.04 i got into problems with using Firefox. I it running on x11 with proprietary nvidia driver, no matter of source package (snap or deb from the Firefox repository) and no matter of safe mode the Firefox gets frozen when clicking into any dropdown control in side page, the same happens when trying to open bookmark folder in the bookmarks panel or even the dialog that opens from the star icon in address folder that should add page into the bookmarks. When running on command line, in case of the snap version there are just some warnings of some missing css file, in case of the deb version it does not output anything suspicious. I was even trying to change the UI theme (qt) as well as GTK theme in case it makes any difference, but it did not... Thanks for any help.

I use Firefox-Dev(129.0b9 (64-bit)) and Firefox (128.0.3 (64-bit)) as default browsers on my Gentoo Linux system with an Intel i7. Both Firefox-Dev and Firefox crash will visiting some websites. Especially Google maps. I have a Gentoo Laptop with and i3 where I run both Firefox-Dev and Firefox and things run fine. I have more software installed on the Intel i7. Video cards ar different of course.

Here is my ldd: opt/firefox $ ldd firefox linux-vdso.so.1 (0x00007ffc8e584000) libpthread.so.0 => /lib64/libpthread.so.0 (0x00007f0161fe7000) libc.so.6 => /lib64/libc.so.6 (0x00007f0161e08000) /lib64/ld-linux-x86-64.so.2 (0x00007f0162007000)

My current version of Firefox is 149.0 (64 bit) Mozilla Firefox for Arch Linux Arch Linux - 1.0 I am running this on two computers, a laptop and a desktop, both running Arch Linux, currently at 6.19.10. I use the laptop much more, and recently noticed that I cannot upload or download files with Firefox. No file selection window opens and the request is simply ignored. Nothing appears in my Downloads folder. Meanwhile, I also noticed that this function works just fine on the desktop computer. I don't remember making any settings changes. I do have popups generally disabled but can enable them for certain sites. In any case, I have tried enabling popups and redirects completely with no change. I figure there must be something different about the settings on these two Firefox installations, but what? What can you tell me? Or ask me? Thanks.

I read firefox is dropping linux 32. Are there any alternatives?

I only use the internet to watch youtube videos.

I don't feel like having to buy a new laptop for this.

When uploading files with Firefox, I click the upload button, and the file browser window appears to upload files.

For as long as I can remember, it always defaulted to the last folder location that I uploaded a file, but just a few days ago, it stopped working, and always defaults to my home folder.

How can I make the upload window pop up, default to the last uploaded location? My OS is Linux Mint Cinnamon.

Using: Firefox v132.0.2 (64-bit) for Linux (Arch Linux)

Picture-in-Picture (built-in) not working correctly. Consider attached image e.g., the video is visible, but I can't really use the any of the other tabs visible here. What I noted: I can scroll the other tab/window using mouse wheel when the Picture-in-Picture is in focus, but as soon as I click on any of the other tabs/window, the video goes to background, and hence becomes "invisible".

I did not really know what happened but every time I opened home page, it did not load. It was working before but suddenly it didn't. I have tried writing "about:home" into search bar and it returned nothing. Just a blank page and an empty search bar.

I've checked the settings and it should be fine. Nothing wrong with it. I've checked the flatpak version and its ok. I was able to open my home tab.

I am using Firefox 148.0.2 (64-bit) Debian .deb.

Firefuxxed was refusing to open new tabs so I shut it down and restarted it (always fixes it) and all my pinned and open tabs were gone with no way to recover them, it took me half an hour to manually restore the pinned ones one by one but not all of them as I cannot remember all of them let alone all the open tabs I had (hours of research gone down the toilet).

There should be a way to backup and restore pinned and open tabs so this doesn't happen, the history option does nothing.

OS: Linux Mint 22 fresh install from a week ago Previous version of Firefuxxed updated after this shamossel.

I rebooted my laptop with both firefox windows I had open and possibly a private window too, then rebooted again without touching firefox, and now I can only restore one of the two windows. I checked my recently closed windows in history and there was nothing there at all. Is there anything I can do at all to restore that other window or is it just gone for good now?

When I do "save as " action for an image in the browser it opens dialogue window to save selected image. Unfortunately it displays files and folders in some random order, rather than my preferred order (sorted alphabetically by name, followed by sorting by type).

I can see no rhyme or reason to the way Firefox lists files and folders in the dialogue window, so every time I am saving an image I have to sort things by name and type before I can find what I want.

This is not permanent so I have to repeat this action every time I save an image.

How do I, please set application preferences? to make this setting permanent?

I am now receiving this notice for more and more commonly accessed websites. I get the message if I have https only selected or not selected. Currently receiving for Lowes, Home Depot, American Airlines and more. I can go to a Firefox 135.0.1 browser on a separate desktop accessing the internet through the same router and do not have issues. I suspect I have been upgraded by Mozilla into a less functional browser version for whatever reason that Mozilla does this.

When I have multiple tabs open, around the 6th tab, the entire computer freezes. I have to press the physical button to shut down and restart. This behavior started with the last Firefox update. It doesn't happen when I use Brave browser. What changed to cause this?

I'm running Mozilla Firefox for Linux Mint mint 100 - 1.0 version 141.0.3 (64 bit) on Linux Mint 22.1 Cinnamon. These are the latest versions of Mint and of Firefox for Mint.

I have recently encountered reproducible failures when attempting to download files or save pages to local storage. The target directory is located on a mounted NTFS file system with the options umask=007, user=root, and group=disk. My Firefox browser is running under a non-root user account that is a member of the disk group. However, I consistently receive the error message: “XXX could not be saved because the source file could not be read.”

I would greatly appreciate anyone's assistance in resolving this issue.

I use Firefox 134.0.2 (64-bit) on Ubuntu 24.04.

Some (not all) web sites show up only after a delay of exactly 30 seconds. The attached screenshot shows that this delay is due to DNS resolution. This behavior is reproducible by simply closing Firefox, opening it again and entering the same web site once more. Once this initial delay of 30 seconds for DNS resolving has passed the web site can be browsed normally.

Using Google Chrome, Opera or even the Tor Browser on the same system works without any significant delay. Also a DNS lookup from the console returns data almost immediately.

As the delay is always exactly 30 seconds this looks like some DNS resolver timeout only showing up when using Firefox.

Neither starting Firefox in Troubleshoot Mode nor (as often suggested) disabling IPV6 for DNS by setting network.dns.disableIPv6 to true did help.

Any idea how to fix this 30 seconds delay?

Many thanks for any help, Felix

I recently tried to connect to two different meeting sites. Both times I got a pop-up noting (correctly) that camera and microphone are blocked. I'm able to click to enable the microphone but I never get the option to enable the camera.

I tried going to Settings>Security&Privacy>Camera but that only allows me to remove previously-enabled websites.

Clicking on the settings button in the address bar shows audio and recording settings but no camera.

What am I doing wrong?

Fedora 42 Firefox 145.0

Can’t launch Firefox 3.5.19 on Linux Ubuntu When trying to run with:

./firefox

Terminal gives the following:

./firefox-bin: error while loading shared libraries: libdbus-glib-1.so.2: cannot open shared object file: No such file or directory

Ubuntu - I use the SNAP version of Firefox - I generally have lots of tabs open but only use 5 or so of them and it's generally fine.... but when I am closing Firefox, it USES like 100% of the CPU and ALL of the RAM and ALL of the SWAP memory when closing.

This locks up the computer.

Sometimes it doesn't quite go all the way but I can watch it all happen in real time, using Task Manager - and that shows a solidwall of all resources occouring, when the close Firefox is run.

I am told by research via ChatGPT that this is a very real problem with the SNAP version and it's best to change to the Debian version, copy all the bookmarks etc., across and then uninstall the SNAP version.

It's rather disconcerting to have Linux crash because of this one app locking it up and frequently.

Chat GPT:

Is there a problem with Firefox Snap Version closing and using all the resources while doing so, which results in locking up the computer?

You're definitely not imagining it—there have been reports of Firefox's Snap version consuming excessive system resources (CPU, memory) and even causing lockups or hangs, particularly during closure. Here's what’s going on and how to mitigate it:

What’s Happening with Firefox Snap?

2. Browser Hangs or Locks the System on Close

On Linux (especially Ubuntu), users have reported that closing Firefox can lead to it hanging in memory, sometimes unresponsive and still consuming resources.
Super User
Ask Ubuntu
A stark example from Reddit illustrates the severity:
“About 50% of the time I open Firefox, it'll reach 100% CPU usage in about 30 seconds… PC completely unusable unless I shutdown.”
Reddit

3. Known Wayland Sway Bug

On Wayland/Sway setups, reloading Sway while Firefox is open can trigger intense logging, causing high CPU use and an enormous syslog.
Fix: Set MOZ_DISABLE_WAYLAND_PROXY=1, or upgrade to FF 125 where the issue is addressed.
Reddit+1

Alternative Approach

Many users, particularly on Ubuntu, opt out of Snap completely in favor of the .deb package or PPA builds. These alternatives often avoid these specific issues. Ask Ubuntu Reddit

Thoughts? Solutions?

Thanks in advance.

I'd been trying to download 2 large files from Icann and kept getting premature completion with Firefox. It would be showing ##MB of 356MB downloaded for a few seconds and then out of the blues it just says completed. As you can see in the shared video, I've tried this several times.

I thought that maybe one of the Firefox addons was causing the issue so I tried Troubleshoot Mode but that resulted in the same behavior.

I then went into Firefox Profile Manager and created a new profile. But that too had the same behavior - 🤔!

So I then tried Chromium. It completed the download successfully and the file passed gunzip test.

So, why is Firefox, even with a new profile, failing to complete a download?
