Firefox Support Forum

Hello Volunteers,

Ubuntu crashes while moving around a Firefox tab with a mouse, IF the mouse cursor goes thru the top bar of the laptop screen. I am using Firefox V 113.0.2, Build ID: 20230522193126 on Ubuntu 23.04. This could be an Ubuntu problem or a Firefox problem.

Thanks Dilip Deodhar

OS version: Ubuntu 22.04.1 LTS (jammy), 64-bit (amd64, x86_64). Firefox version: 110.0 (64-bit) (NOTE: the issue was noticed with version 109.0, too)

Firefox package was installed on Ubuntu through 'APT', using the Mozilla Team repository (https://ppa.launchpadcontent.net/mozillateam/ppa/ubuntu/). It caught my attention that an excessive amount of Firefox related 'DENIED' AppArmor log messages is generated during the browser activity.

According to messages, Firefox is occasionally denied read access to '/sys/devices/' area and read/write access to 'oom_score_adj' target in '/proc/'. Could somebody clarify why would that access be required for regular browser operations? I'm a bit puzzled as I haven't noticed anything similar with the older Ubuntu and Firefox versions. A complete suppression of those messages is also an option as long as there's no negative impact on application's performance.

I already posted this question to Ubuntu forum but seems like nobody there could provide an explanation. I'd appreciate any input or hint.

Following is the sample of referred log messages:

Firefox worked perfectly, but since a few days I can't download anything. I'm using Mozilla Firefox snap for Ubuntu 22.04, version 110.0.1 (64 bits) canonical-002 - 1.0 With Chrome everything works perfectly so I assume it's a problem from Firefox.

When I open a PDF, a MP3 or any file, the "save" option doesn't display anything. Usually it opened a dialog where I could choose the folder where I wanted to download the file, but now I have nothing.

I have only 4 extensions: - adblocker ultimate - duckduckgo privacy essentials - vuejs dev tools - zotero connector

I always had them and I never encountered any problem.

After installing Ubuntu 20.04 LTS Clicking on Firefox or Thunderbird it hangs the computer and have to switch off the computer on main switch. Reinstall Mozilla once but no difference still hangs Ubuntu. Need help on this one Thank you

This problem has been around since the latest version of the old version, and has carried across into the new version. Ctrl+A, Ctrl+C and Ctrl+V no longer work with Google Translate on linux. I have tested in other browsers and it they all work fine. Firefox on Windows also works fine, this problem seems specific to linux.

When you press any of the Ctrl combinations it simply deselects everything and moves the cursor to the end of the text. Mouse works, but it's not practical if you are cutting and pasting all day long.

Site: https://translate.google.com Firefox version: 89.0.2 (64-bit) OS: Ubuntu 20.04

Google Translation is critical to my work so my current solution is I no longer use Firefox. I hope that someone knows of a quick fix, or if it's a bug it's easy to fix as I'd hate to permanently move away from Firefox for something like this.

Thanks!

Hello.

90.0.2 (64-bit) on Ubuntu 20.04.

I noticed a lot of activity from my desktop computer to various ip's at bc.googleusercontent.com whenever I start, visit sites, or shut down firefox. I know this because I'm watching the tcp stream with tcpdump | grep 'googleusercontent'

This ONLY happens in Firefox not chrome or other browsers. Seeing this is a fresh install with no addons, tweaks, etc. I'd like to know WHY a fresh install of Firefox phones home to some googleusercontent user. See below snippet of logs:

In linux (ubuntu) I have some serious issue when I open firefox the tabs are going to white and I don't see any buttons and website. But When I Hovering the firefox in mini window i can see browser but in full screen there is only white screen as you can see in image I attached.

Hello everyone, i'm currently on ubuntu 20.04.2 LTS, and pretty frequently 1/2 times a day, when I'm on youtube, the browser just starts messing up completely the audio. It is delayed by at least 2 or 3 second, and it is all confused by a really awful interference noise. The problem goes on if i don't restart my browser, or sometimes even my pc. I tried disabling hardware acceleration but it doesn't work

Problem appeared in the last few days so I assume it is due to the recent update - 91.0.2

Clicking the Menu button (3 bars), the button goes grey but the application menu does not appear. If I move the mouse around, I see flashes of the menu but that's all. A graphics problem?

I have also found that copying and pasting is inconsistent. Sometimes it works sometimes it doesn't. Sometimes it flashes. No problem in Thunderbird or other applications.

I have tried reinstalling Firefox - no difference I have tried Firefox in Safe Mode - no difference

Any advice gratefully received

When video/audio starts playing on a browser, the tab title displays 'playing' text. This additional line resizes the window height and causes the tab content to resize too. For example youtube starts resizing video window height and width - and this is very annoying. How do I remove 'playing' text from tab FOREVER?

This question was asked 6 months ago and I have the same problem.

Running Ubuntu Mate 21.04 (metacity), FF 91.0.2 (64-bit). I have it set up with two different profiles, with separate menu entries for each using "firefox -P [PROFILE NAME] -no-remote %u". One of them is set to always use private browsing mode and I use that profile as my default app in mate.

If if set chrome as my default browser, I can open links from other apps without a problem regardless of chrome being already running or not.

When I set FF as default, whenever it is already open and I try to open a link, I get a "Firefox is already running, but is not responding. To use Firefox, you must first close the existing Firefox process, restart your device, or use a different profile." error.

I've seen some comments about similar issues with wayland and tried setting MOZ_DBUS_REMOTE and even MOZ_ENABLE_WAYLAND to 1.

Can you help me?

What is going on with Firefox on Linux? It's been my favorite browser for years and I want to stick with it, but it becomes unusable.

I've got 32GB of RAM, so I should theoretically be able to open quite a few tabs (which I need as a web developer), but when I have about 15 tabs open, it consumes about 1GB of ram per tab. Usually I have some webmail tabs open, google drive, youtube, some documentation and references, github, example sites... you know, the usuall stuff you find in a web dev's browser.

I'm running the latest updates on Ubuntu 20.04 and have the latest Firefox installed. On my Windows (dual-boot so the same computer, but windoze is more for gaming than for work), I can open 50 tabs and have no memory issues at all. I'm syncing my extensions so it's the exact same configuration, yet on Linux it's huge a pain in the behind to keep using it.

Are there any fixes for this? I've seen other complain about similar issues for previous versions of Firefox and other Linux distros, I've ran through all the self help suggestions and nothing helps.

I'm running Linux Ubuntu 20.4

Whenever I try to use a website that has a browse button (e.g. youtube uploader, google drive, etc) I click it but nothing happens, no file browser comes up.

As per previous discussions on this issue, I have tried Safe mode, refresh (in fact total new operating system and re-install of firefox) and disabling hardware acceleration, even turning off popup blocker and none of these have made any difference.

I'm running version v92.0 (64) on ubuntu 21.04. Firefox would crash upon opening when signed in. It would stay active enough for me to disable the extensions & themes. After doing that it still crashed. I tried going into Troubleshooting mode and it would still crash. I went into Troubleshooting mode and did a refresh. It was still crashing. Finally I signed out of my mozilla sync account and the browser has stayed active long enough for me to type this report.

I've submitted all crash reports in about:crashes, and I'm not really sure what to do next.

Perhaps a local version of the Mozilla Sync profile has been corrupted? if so, is there a way to remove it and pull down the "sync"ed version from Mozilla's servers? What if the version on Mozilla's server's has been corrupted? should I back up the local profile (wherever it is) before removing?

I hope I've given enough information. Please let me know if you need further, more specific information.

Hello,

what can i do when i get a message "Sorry. We just need to do one small thing to keep going." with <Restart Firefox> or "Gah. Your tab just crashed." all the time i open firefox? A restart with Add-Ons disabled does not help. I send the troubleshooting information from Help/Troubleshooting information. As one can see Firefox does not seem to produce crash reports either.

Kind regards Atomino Zweitausend

Version 92.0 (64 bit) Ubuntu: 18.04, 20.04

For a couple of months, I have not been able to resize the FF window. Consequently, I abandoned FF for Chrome. I've just upgraded my os to Ubuntu 20.04 (from 18.04) so I thought I'd try FF again. The problem persists.

Minimize/Maximize work fine, but when non-maximized, the resize "handles" don't show up (see attached image). I've tried safe-mode, as suggested by some previous post, but it hasn't helped.

Hello, I am using Firefox for many years with Ubuntu but recently Firefox started to transcript Cyrillic page into Latin ones. I tried to change some of the language settings, but nothing worked. My standard language is German. How can I make Firefox show the pages in Cyrillic alphabet? Thank you for your help.

On certain websites this "Geckomain" process destroys my CPU to 100% and maxes my network traffic with more upload traffic than download, using a lot of my data and bandwidth etc. This is a major concern because I have to pay for my data, it's not unlimited. If left open this process will consume more than 1.5gb of RAM while nothing functions. The only way to stop it is to leave the website. I have to use these websites for my job, so I can't just avoid them. I need a resolution ASAP. Thank you.

When I click the fullscreen button on a video, such as YouTube or Netflix, I find that upon exiting the fullscreen video and going back to normal screen, Firefox's window size is now maximized, when it was a smaller window before clicking the fullscreen button.

I am running Ubuntu 21.10 and I don't recall having the issue in previous versions.
