Firefox supportforum

Greetings:

First experienced: Friday, Sept 2, when using burpsuite/foxyproxy during a hackerone CTF.

When using other Vbox instances on the same computer I have the same issue. This issue is usually easy to duplicate when using dev-tools or by simply doing an image search and moving the mouse across the images.

Host: Ubuntu 22.04.1 LTS 5.15.0-47-generic #51-Ubuntu SMP Two different VGA controllers are present: Intel CometLake-S GT2 AMD/ATI Ellesmere Radeon RX

VirtualBox: 6.1.34_Ubuntu r150636 (Qt5.15.3) VirtualBox VGA: VMware SVGA II Adapter

Guest: Kali 2022.3 rolling 5.18.0-kali5-amd64 #1 SMP PREEMPT_DYNAMIC Debian 5.18.5-1kali6

Crashes have seem to involve input from the mouse and scroll function within the browser. Once, let us call it a glitch, the crash can either take place while continually moving the mouse around the browser's page or immediately outside the page with the mouse. The "glitch" is a coloration, usually pink or lime-green with characters printed to screen and then disappears. I have been unable to predict when the glitch will happen, thus no screenshot to help.

Steps I have taken:

Googled on the problem which led me to learn about the Firefox about:crashes function.

Viewed about:crashes -- seems to be a Renderer issue linked to llvmpipe or Mesa?

Checked basic system logs for host and guest for anything evident: syslog, kern, Xorg, messages, dmesg, daemon, journalctl.

Used Firefox troubleshooting and extended troubleshooting.

Installed Firefox 104 with same issue.

Reinstalled VirtualBox.

Search on Firefox Renderer issue [from crash report]

     I turned off performance settings, still have same crash issue.

Last Report ID that did not fail to upload: bp-740acc47-0ed4-44a8-851c-ff21b0220905

Ultimately, I am unsure if this is a Firefox, VirtualBox, or Kali Linux issue, but Firefox is the one that this issue is having a severe impact on. My head is spinning at this moment due to all the logs and information I have digested over the weekend.

I appreciate any efforts in helping me decipher what is going on!

Respectfully,

Steve

Maximizing and minimizing are still normal, but Firefox windows could not be dragged now.

$ lsb_release -a No LSB modules are available. Distributor ID: Ubuntu Description: Ubuntu 22.04.1 LTS Release: 22.04 Codename: jammy

$ which firefox /usr/bin/firefox

Firefox unter ubuntu 22 hat keinen Zugriff auf die lokalen Dateien (z.B. /usr/share) Der 'open' auf '/usr' scheitert mit 'read'-Zugriffsrecht.

Ganz egal, was in '/etc/apparmor.d/usr.bin.firefox' respektive in '/etc/apparmor.d/local/usr.bin.firefox' spezifiziert wird, das Zugriffsrecht für '/usr' ist immer 'read'.

Wie kann man auf die Dateien unter '/usr/share' zugreifen?

I often use two firefox windows each with several tabs opened

Problem is when I quit in this state sometimes only one of those multiple windows gets opened on the next launch

To quit I do a `ctrl + q` or right click `Quit` from launcher bar

Is there a setting to tell firefox to always relaunch with the same set of windows ?

I use sync and this happens when using the same computer for the exit then relaunch of firefox

Hello, I've upgraded my Ubuntu distribution from Ubuntu 20.04 to 22.04 yesterday. This forced me to update my Firefox version, I am now running the 104.0.2. I now have the following issue: on some websites, the page loads normally but as soon as it's loaded, the page becomes entirely blank. This doesn't seem to be a website issue, as it actually appears normal for a very short instant before it disappears. A website for which this happens is: https://www.lalibre.be/ (I only encountered the issue on another website but it's from the same editor). I tried in a private window and it works normally! I tried in the normal window after deactivating all the addons, it still doesn't work. I tried with or without the Firefox account logged in, it doesn't work. Until now, it's only these 2 websites from the same editor, but as I said, they worked fine yesterday, they work fine on other browsers and they work fine in Firefox private mode. Any idea where this might come from?

Starting today, with firefox 102 (on Ubuntu 20.04), I cannot open a url using the address bar. If I enter a url and then hit Enter, it brings up my selected search engine looking for that url, not opening the url itself. This has not happened before today. Is there a way to use the address bar only for opening addresses, and use the search bar for searching?

I can't get Firefox to use some custom cursors. Firefox is only recognizing the cursors that came installed with Ubuntu. Any of the cursors I installed will default to DMZ-White, but Firefox is using those cursors that came installed with Ubuntu. I tried defining the default cursor in /usr/share/icons/default/index.theme but did nothing as well. Also I tried with the cursor in /usr/share/icons and in /home/name/.icons and firefox cannot get in any of those.

I don't know if it's something wrong with my cursors or it's some inner thing with Firefox, any one has a guess? Incompatibility or something missing from the cursor?

Hello, Firefox friends!

I'm having some issues with Firefox on my Ubuntu system and I'm really hoping someone can help me fix them.

   Problem with Downloads: When I try to download something and click on a link, a new tab opens. But then it immediately closes and nothing downloads.

   Button Issues: Some buttons within Firefox just don't seem to work.

I've tried a few things already:

   Checked for Firefox and Ubuntu updates
   Ran Firefox in Troubleshoot Mode
   No antivirus because I'm on Ubuntu

If anyone has faced similar issues or knows how to fix this, please help!

Thank you so much!

Crash report submitted bp-37f84164-6125-4ae1-9e55-8a8200230225. Started happening about once a day over last few days possibly since 110 FF update (Ub kernel was also updated a few days back) Have to do a hard power off & restart

Whenever a website prompts for me to upload or download a file and I except Firefox crashes, quitting in its entirety. This still occurs in "Troubleshoot" mode so I assume it is not any of my extensions. Here is a crash report from when this occurred if it helps. Another odd observation I made is that I am able to upload a file if I use a "drag-and-drop" feature on a website.

Hello, This issue might or might not be related to [other issue] I have since I updated Ubuntu 20.04 to 22.04 and therefore updated my Firefox to 104. I can't login anymore on Letterboxd since the update. It's not a problem of username or password. When I click "Sign in", nothing happens except a page refresh, but I'm still not logged in. Other strange behaviour on that site since the update: most of the images don't appear. For example on this page : https://letterboxd.com/films/# all the movie covers are just blank.

The website does work properly when using Firefox in private mode though (both login and images work fine), so this makes me think it's related to my other issue mentioned above.

OS: Ubuntu 22.04 Firefox 104.0.2

EDIT after posting this question: I just found out that I can't login on Google either. I enter my username, password, then it asks me to validate on another apparel that it's really me, which I do, and nothing happens so I can't login. It works normally in private mode.

I first realized an issue with downloading PDFs through the Firefox viewer - I cannot. The download button does nothing, there is no prompt, no popup, and no file downloaded. I have also tried to print to pdf, that also seems to fail.

Today I realized I also cannot attach any files to an email through Gmail in Firefox, which is now leading me to believe that the software is unable to interface with my files at all.

Things I've tried include: - Turning off popup blocker - Refreshing Firefox in the ->Help->More Troubleshooting Information Menu - Starting Firefox in safe mode - Reinstalling through snap

The only way I can currently download files is through wget, and the only way I can send attachments is by installing Google Chrome, which is kind of a last resort for me.

I am running Ubuntu 22.04, this is on Firefox 106.0, though it didn't work last update either.

Thanks for any help

Edit: I have been googling for answers but after posting this question a similar thread popped up, the solution is to install the following packages:

xdg-desktop-portal xdg-desktop-portal-gtk

I'm following a tutorial to install cinnamon desktop which includes Firefox snap on my Ubuntu LXD container, but the installation with snap fails. Does anyone know why it happens and how to fix it?

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:

Hi, wonderful crew I have this annoying issue: when I want to print a page and I open the Print menu from the "hamburger" button, the preview open but on the printer list I can see only the PDF printer, not my default printer or any other printer. Also if I click on the link "Print thru the system printer window" I see only "Print on file" and "Print on LPR" I tried the same on Chomium and there I can see my default printer My system is a Ubuntu desktop 22.04 recently updated from 20.04 LTS Thank for your work

My OS is Pop! OS. Using 'Tidal' as a web based music streaming service and I play vids on YouTube. Every time a new song or video starts, or when I skip, rewind or do anything like that, it auto resets the volume level output in my sound settings to about 75 to 80 % of the max possible level. So basically, I have to adjust each and every new song by hand, it is infuriating. I block facebooknet in Umatrix and firebaseinstallation googleapis as well as google tag manager but nothing else. That's on Tidal, similarly I do not block essential cookies on YouTube, so I don't think that is the problem. I have a hunch that the answer is somewhere in about:config. If this is intentional, then I'm giving up hope. Thank you.

When plugshare.com loads, there is a prominent search box at the top left corner. However it is missing the menu icon (see attached pic) as well as the search icon. This is happening on 2 different machines running Ubuntu 22.04.

Please fix. Google Chrome displays just fine; see attached pic.

In my firefox the file input is not functioning at all.

EX: I go to https://www.w3schools.com/tags/tryit.asp?filename=tryhtml5_input_type_file and try and use any of the file inputs there - they just do nothing.

Same with the file inputs on this support form page. None of them work for me.

System - ubuntu22.04, ff: 106.0.1 64bit

OS - Ubuntu22 Firefox - Default firefox on ubuntu22 (Mozilla Firefox 103.0.1)

Use case - 1. Custom profile folder (named prof1) contains pref.js and chrome folder with custom css file. 2. prof1 is created in -> "/customData/profiles/prof1" 3. The folder "/customData" has full rwx permissions and is owned by $USER (not by root)

Output -> 1. When launching firefox mentioning the profile -> "$ firefox --profile /customData/profiles/prof1"

The browser does not load, but there is an error box saying Profile Missing Your Firefox profile cannot be loaded. It may be missing or inaccessible.

Questions -> 1. Is it possible to load firefox profile from root directory ? 2. If custom profile folder is created in "/home", then it is launching and working perfectly. How is this possible when the permissions and owner is same as the one in "/customData"
