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?

I am experiencing an issue with the Picture-in-Picture (PiP) functionality in Firefox on Ubuntu. Unlike on Windows, where the PiP window automatically appears when switching tabs or pages, this does not happen on my system.

When I manually activate the PiP feature by clicking the button, the window does appear; however, it is placed behind the browser window and remains at the lowest level among other open windows. This causes it to be obscured by other applications and requires me to manually bring it to the front and adjust its position every time.

Is there a way to automate this process or resolve the issue so that the PiP window behaves as expected (i.e., stays on top of other windows and works seamlessly)? Please let me know if there are any settings, extensions, or workarounds that could address this problem.

Thank you in advance for your assistance!

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

That is the first line in the Hippocratic Oath. All doctors have to swear to it. All software developers should too.

I made the mistake of letting Firefox on KUbuntu update. It obliterated all my tabs and all my history. There's nothing left. I had a lot of tabs open with intent to use them to update some astronomy instructional activities. I don't know if I'll be able to find them again.

I don't really have a question except to ask: What fresh hell is this? Is it really that hard to just leave things the hell alone? I'm afraid to ever update Firefox again. If everything else wasn't based on Chromium, I'd be out of here.

Also, it looks like something out of Windows 7.

It's all gone. It's a wonder you didn't delete all my bookmarks while you were at it.

Firefox 136.0.1, Linux 6.8.0-55, have set Okular as default pdf application, however Firefox will not open pdf file when downloaded nor will it open the file when selecting Open File from the Download Icon on the toolbar. Only was I can get to file is to select Show in Folder option and open from within Dolphin.

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.

For some weeks I have ad an issue with Firefox using 50%-100% of CPU. Normally it is the Firefox process itself, sometimes it is also "Privileged Cont".

OS is Kubuntu 24.04. Firefox has done this across 2-3 versions.

Things I have tried:

Restarting Firefox No change, I'll even get 100% cpu usage with no tabs open

Refresh Firefox to remove settings and addons No change

Uninstall Snap and try direct Apt package No change

Remove ~/.mozilla to fully remove any residual settings/cache/etc No change

Try with and without hardware acceleration See: https://support.mozilla.org/en-US/questions/1308215 No change!

I would blame my old computer hardware, but Brave runs fine. I am now using Brave, but would dearly like to return to Firefox as I miss containers, and I don't support a chromium dominated web.

apparently, programmers don't understand how aggravating not having backward compatibility is to the rest of us, so please bear with my extreme aggravation here. IF IT AIN'T BROKE, QUIT FIXING IT.

 firefox disabled my addons, thus forcing me to upgrade, and now I am angry. Tried downloading the new version several times. My os is as updated as it can get. Using the APT link from this site, it just shows garbage. Using the download for linux 64 bit link, it makes me jump through hoops and looks like it is working, but it looks different and none of my bookmarks transferred over. Closing it down and reopening it, I see the old version, thus making it look like I am possibly running both versions separately. Once the *all new singing and dancing special that is supposedly so much better than the old that some ignoramus decided I MUST use it instead of the old and functional one* is closed out, I see no way to reopen it. And neither version will enable or allow me to download singlefile. That is the only program I need from firefox at this time.
 Will somebody please show me, step by step, as if I am 5 years old, a back door that will enable my addons, before I go nuts and start beating programmers to death with reams of algorithms?

very frustrated, and pissed at how programmers always screw things up that are working just fine by upgrading crap. Now, I have suddenly had all of my addons quit working, was forced to update my firefox. Nothing changed, and it still shows that I am using version 105, instead of the all-new, better and fancier, singing and dancing crap that is being forced upon me.

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.

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?

Have an old computer and running Ubuntu

Want to keep Firefox but old man and don’t understand certain aspects

Could somebody email me a link that help? Is there such an animal?

Firefox 135.0 (64-bit) on Ubuntu 22.04.5. When trying to save any file (download, save image etc.) or trying to attach a file (in web-based gmail client or WhatsApp web client) nothing happens. Tried to refresh, switch off all extensions, clear download history - nothing helped. Chrome works on the same machine like a charm...

Do you have any suggestions?

Thank you
