Firefox does not seem to be properly configured for Wayland on KDE Plasma 6.x systems. The generic "Wayland" logo appears in task switcher instead of the Firefox logo. Firefox is the only program I have with this issue. Setting desktop name (org.mozilla.firefox) as a property in the Window and Application Manager settings does not resolve the issue.

Hello

Recently I've upgraded from Kubuntu 24.04 to 24.10. I'm almost sure that the minimize/restore buttons were available in my Firefox after the system upgrade. For the last few days I can see they are missing - please see attached images.

I can partly fix the problem by going to Settings->More tools -> Customize toolbar and selecting "Title Bar" checkbox. In that case I have the title bar displayed with all 3 button (minimize, restore, close).

But I would like to have the default behavior: title bar is turned off and the mentioned 3 buttons be visible in the tab bar.

How to have those buttons in the tab bar when the title bar is turned off?

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.

Subject: Assistance Required for Frequent Firefox Crashes on Ubuntu

Dear Developer Team,

I am facing persistent issues with Firefox crashing on my Ubuntu PC, and the problem has been ongoing for the past 40–50 days. Despite multiple attempts at troubleshooting—including uninstalling and reinstalling Firefox, clearing all caches, and other measures—the issue remains unresolved.

I’ve noticed that Firefox works for a few days after reinstallation, but then problems begin to surface, such as a half-screen display. Eventually, after restarting the PC, the browser starts crashing again.

Could you please investigate this matter urgently and provide a resolution? Additionally, I would appreciate it if you could clarify whether this might be related to a RAM issue or some other underlying cause.

Looking forward to your assistance.

Best regards, zimmi

What settings do I need to get Street View to return the street view rather than a black screen in all 4 of my Ubuntu browsers, when it used to work fine but now is trash ?

Every 1 - 2 hours Firefox stops loading pages and I have to shut it down and restart it and restarting takes around 6 clicks on the icon to get it to start.

Also one time today I lost all my pinned tabs and had to manually restore them one at a time.

Using Ubuntu 24.04.2 and latest Firefox. Cleared cache but doesn't help.

YouTube keeps putting up the add block detection when I try to play a video. Apparently they can detect Add block Plus. Kubuntu 24.04 Firefox version 130.0 [64-bit] Mozilla Firefox Snap for Ubuntu Canonical-002-10. Add block Plus version sorry I can't find that information.

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.

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!!!

Firefox in Ubuntu Linux is broken for about 30% of the web; only CHROME works. This problem just keeps getting worse. Please fix; it doesn't matter whether FF is more secure, if it doesn't work - what's the point?

Since I updated to Firefox 141.02 I have not been able to play videos on Paramount+ or Netflix. I get an error on the top that says the Widevine plugin has crashed on both streaming services. I have checked that the plugin is on and there are no updates. I am on Ubuntu 24.04. Video on YouTube plays as normal

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

Hi all. I have been using firefox with ubuntu 22.04 for about since when ubuntu 22.04 was released (2022).

On firefox, I usually use the nordpass and tab grouping extensions. For the third or fourth time in a row, firefox has simply vanished from my system from day to night.

I click the icon and nothing happens. I try typing "firefox" in the terminal and get

   Command '/usr/bin/firefox' requires the firefox snap to be installed.
   Please install it with:

   snap install firefox

Even if I accept the bizarreness of snap simply deciding from one day to another that I don't have this package (or did I never have it and never needed it in the first place?) and try "snap install firefox" I get:

   snap "firefox" is already installed, see 'snap help refresh'

After reading the result of "snap refresh help" I decided to "snap refresh" to update all of it's packages. Still, "snap install firefox" and "firefox" keep giving me the same result.

What is happening here?

I am running Lubuntu 22.04LTS (have been for months now), with Firefox 130.0.1 installed via the normal vanilla apt.

It was working fine until a few days ago (perhaps after an update, but I can't recall specifically), and then just stopped being able to save anything.

For example, right clicking on an image will bring up "Save As..." as an option, but when I choose that, nothing happens. No prompt to save, nor does the file appear anywhere.

When I choose "Save" as a pulldown on cloud XLSX files...similarly, nothing happens.

When I download something, Firefox is supposed to open up a prompt asking me where I want to save the file but that never opens...nor does the file download.

I am totally baffled.

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???

I am trying to sync Firefox data to new computer. The Mozilla account only allows me to sync mobile devices. Online instructions do no match my version of Firefox 131.0.2, Ubuntu 24.04.
