I'm on Ubuntu 22.04 which is using the snap package of Firefox.

It seems that I cannot open local files in the /tmp directory. When I place a test.html file there and run `firefox /tmp/test.html`, it returns a file not found error. Why?

I don't have the problem with files in my home directory.

Hello,

I've spent several hours today trying to fix FireFox slow start up on my system. After start up (about 2 full minutes), everything works normally. The hardware is an ASUS A88xm-A MB, A10-6800K processor, 16G DDR3, runs OS and programs off an SSD. I worked through all the slow startup suggestions, ran memtest (0 Errors, 1 Pass), disabled all add ons, (even the OpenH264 video codec (I use the onboard HDMI, no graphics card)), turned off hardware acceleration, etc. When starting in troubleshoot mode, less than 30 seconds, (acceptable), but I really don't know where to begin with the "More Troubleshooting Information" when I look at the table generated by it. There have been no other problems to date with the system, and the long start-up time began with 20.04 Ubuntu (about a minute), then got worse when I upgraded to 22.04 to try to solve THAT problem. Currently running FF 104.0, and the update page says wait for a distro update if that is how it was installed. I believe 104.0 is the latest Linux 64b version though. All updates to the system are done as soon as I'm notified of them. there have been none since the upgrade a few days ago.

Any suggestions? Gotta get some sleep now... TIA, Dave

I'm running Firefox 99.0.1 on Ubuntu 22.04. Recently (I think since I updated to Ubuntu 22.04 about a week ago), Firefox has been refusing to show me file upload dialogs. When I click a button that's supposed to give me one, nothing happens.

This has been happening with: - The "attach files" button in Gmail - A file upload button on Gradescope (website for managing homework assignments) - File -> Open File... and Ctrl+O.

Dragging and dropping a file onto an email in Gmail does attach the file -- it's just that the button doesn't work.

I've tried restarting, and I've tried running Firefox in Troubleshoot Mode -- so far nothing has fixed the problem. What else should I do?

Hey there,

Intro: I recently switched to Linux and (because Brave is so broken) also to Firefox and I am liking it so far.

Problem: Unfortunately I can't copy-paste files from Ubuntu Files (Nautilus) to Firefox (I tested image files and also sounds files, neither is working).

Test with Firefox: 1. Download a random photo (e.g. from Unsplash) 2. Select the file and hit ctrl + c in Files/Nautilus 3. I go to the clipboard inspector 4. I hit ctrl + v 5. The image does not show up in the output (see screenshot)

Test with Brave: 1. Do the same as above 2. The image does show up in the output (see screenshot)

Notes: - I am using Linux Ubuntu 22.04 with Wayland - Firefox Version 107.0 (64-bit) for Ubuntu Canonical - 1.0 - I have no extensions installed - I am not using the snap version (so I can scroll smoothly) ... I think I used apt-get install but not 100% sure

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?

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.

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 am using Firefox 95.0.1 on Ubuntu 20.04. When I want to use an add-on in google docs, I see this error screen in Firefox. Opening the add-on in a separate window does not work either and even if it did, it would be off the purpose of a google doc add-on. How can I solve this problem?

Hello all,

For some reason, I can no longer upload or download files, with the pop-up window failing to appear entirely. I can upload folders through, for example, Dropbox or Google Drive, but individual files don't work.

I've reset my browser, uninstalled and reinstalled it, opened it in troubleshooting mode, disabled enhanced tracking protection, but nothing seemed to work. I've tested another browser, and I was able to upload and download files just fine.

Is there anything I can do to fix this? I'm on Ubuntu 22.04 using Firefox 107.0.1.

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

Noticed geo.provider.network.url setting in about:config no longer works in firefox 102.0 ubuntu. I use it consistently so it was easy to notice that it no longer had any effect after updating.

tested both on https://maps.google.com and https://browserleaks.com/geo

Is it possible to revert to an older version without losing my data?

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 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:

This was going to be a question about Firefox being unable to display the file picker dialog, but I managed to find a solution that worked for me along the way. Since it was nowhere near the top of Google's results, I thought I'll share my solution in the hopes that this would help someone facing this same issue.

The hardware:

• Asus UM425IA Zenbook (AMD Ryzen 7 4700U CPU)

Worked in:

• Ubuntu 20.04 LTS
• Firefox provided by APT repository
• Xorg display server

Not working in:

• Ubuntu 22.04 LTS
• Firefox 99.0.1 provided by snap
• Wayland display server
• File picker worked briefly on fresh install, but something (not sure what) quickly breaks file picker functionality

The symptoms:

• Firefox stopped being able to open file picker dialogs
• Right clicking an image and selecting "Save Image As..." does nothing
• With forms that accept file upload (such as on this post question page "Add images (optional):"), clicking "Browse" does nothing
• File downloads work correctly when set to "Save files to ..." under Settings, but nothing happens when set to "Always ask you where to save files"
• No response to "Ctrl + O" open file shortcut

Similar questions and solutions:

• Fixed by reinstalling Firefox
• Fixed by resetting Firefox
• Fixed with a restart on a Mac
• Fixed by downgrading to Ubuntu 16.04

Things I tried that did not work:

• Disabling hardware acceleration
• Starting with add-ons disabled
• Troubleshoot mode
• Clearing startup cache
• Clearing cookies and site data
• Clearing history
• Refreshing Firefox
• Creating and using a new profile
• Deleting the `xulstore.json` file from the profile directory
• Toggling all permissions under Ubuntu Settings > Applications > Firefox to off and then back to on
• chmod 777 ~/Downloads
• Disabling native file picker "ui.allow_platform_file_picker = false"

And finally, what fixed it for me was to go into "about:config" and change "widget.use-xdg-desktop-portal.file-picker" from "2" to "0". Credit to this post that clued me in.

I really hope this saves someone else 2 days of hair pulling and I would appreciate advice from someone more knowledgeable than me on:

• Why this fixed the problem
• Whether I should be opening a bug report either against Firefox, or Ubuntu
• Whether I should also be changing "widget.use-xdg-desktop-portal.mime-handler" and "widget.use-xdg-desktop-portal.settings", both are currently set to "2"

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"

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.

HELLO very small cursor on Firefox windows (on all other windows the cursor size is normal) via snap after upgrading to ubuntu 22.04.1 LTS. how can i change it? Thank you

This the second time I am entering this problem -- the first time Firefox refused to let me return to this site.

First, I am running Firefox on Ubuntu, but Ubuntu is not relevant because the same issue occurs in Windows.

Whenever I access a file, for example, one at https://species.wikimedia.org/wiki/Chioneosoma, its color (which is programmable) changes from a light bluish green to a deeper violet. Where is this color-difference stored? I have thousands of WikiSpecies files I have accessed, and they all show the violet "accessed" color if I ever have opened the file to read its contents. The problem is that when Ubuntu has to be reinstalled, I can add references to all my files, but the color-changes seem to be lost. This is a serious issue, because I currently have over 50,000 files referenced (and saved in my directory file:///home/jwill/Documents/WikiSpecies/Animalia_Plantae_8) and am still adding to them!

I think the storage location must be somewhere in one or more of the following files ('_' replaced '/'):

   _home_jwill_.mozilla
   _home_jwill_.cache_mozilla_firefox 
   _home_jwill_.cache_MM_firefox
   _usr_lib_firefox

Can you please tell me where the list of accessed files is stored? Whenever I enter a referenced directory, to access it, the color changes; so, Firefox must be able to store a reference to each new referenced directory name.

Local Machine: Dell Inspiron i5-7200 / 16 GB RAM / Local Op Sys: Ubuntu 20.04LTS

Firefox version: 99.0 FFDE version: 100.0b5

Node.js version 14.18.1 npm version 6.14.15

I had a Node.js web app running on my local machine all usual browsers like Firefox, Firefox Dev Ed (FFDE), Chromium, Edge, Opera, etc till recently.

Recently it shows an error when run on Firefox (also on Chromium, Opera and Edge) although continuing to run okay on FFDE.

Firefox Error: Cross-Origin Request Blocked: The Same Origin Policy disallows reading the remote resource at file:///home/sandbar/Desktop/nodeapp-local/undefined. (Reason: CORS request not http).

Edge Error: Access to XMLHttpRequest at 'file:///home/sandbar/Desktop/nodeapp-local/undefined' from origin 'null' has been blocked by CORS policy: Cross origin requests are only supported for protocol schemes: http, data, chrome-extension, edge, https, chrome-untrusted.

Naturally, I need to test the web app on my local machine using several browsers before I should upload it to a server and trial it there.

So how do I configure the browser and/or app to allow access to local machine files ?

Brand new installation of Ubuntu Focal (on an ARM Chromebook, using Crouton). Installed Firefox (104), runs fine but as soon as I sign into my Firefox account it immediately crashes. Continues to crash if I start in safe-mode, so I don't think the problem is an extension. After some online research and some trial and error I seem to have determined that I can sign into my Firefox account as long as password sync is disabled. But as soon as I enable password sync, Firefox immediately crashes.

Error message in terminal is always about GPU, which maybe isn't properly set up or maybe Firefox has a problem with it, but if I use the software renderer it doesn't cause a problem (MOZ_ENABLE_WAYLAND=0 firefox). Hard to imagine that this has anything to do with crashing when syncing passwords?
