Firefox Support Forum

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.

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"

I installed firefox as a flatpak on ubuntu 22.10(kinetic kudu) and everything works fine except for one thing,that being the fact that i cant seem to drag bookmarks from one folder to another, as as soon as the bookmark is dragged from the folder towards another dropdown menu the entire bookmark dropdown closses. as soon as that happens i also cant seem to type inside of firefox restarting firefox fixes the latter issue but not the former.

i hope i explained the problem well

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?

Mit freundlichen Grüßen

I've checked a couple of the "similar topics" before posting here. I'm not sure if I am having the same problem or something else.

Back Story: I have a "few" windows and tabs open in FireFox. I would finish what I was doing, shut down and then the next time I booted up and loaded FireFox, all sessions would be restored and all log ins honoured (kept). That is: I was still logged in.

(Moving to now) Yesterday I powered up and ALL sites were logged out. About 20 log ins were needed. Hmmmmm... gmail, and the rest.

"Ok... something happened. No problems, things should be ok from now. I've logged in, so all is sweet."

Today I power up: All logs ins lost. Had to go through it all again.

Gmail is throwing security alerts at me hand over fist. Yeah, that is good in some ways. I get that part. But I've logged in.

Seems - my thoughts - that the cookies aren't being saved. But why? I haven't touched them or their settings.

Yes, I did do a clean out of older cookies. But left the gmail ones, and other sites I know I use. I have `adblocker ultimate` installed.

Now I am logged in, if I open the `cookies` and look I should see them there for the sites to which I am logged in - yes?

To be clear: When I am done, I do NOT `exit` FireFox. All windows, tabs, sessions are left. I just shut down the machine. Then next time I load FireFox and they are re-loaded and log ins are maintained.

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

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?

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.

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.

Hi there,

I'm using my PC for local web development. I use Firefox as my regular browser and recently, in order to distinguish between personal time and development time, I've established a new profile just for development purposes.

The local website I can't reach is "site.local.dev". My OS is Ubuntu 20.04 and that URL points to a local IP on my network (resolved via /etc/hosts file on my PC).

Funny thing is that: - In dev-profile: site.local.dev does not work => "Unable to connect" and the URL bar shows https://site.local.dev even if I force it to http:// - In personal-profile: site.local.dev does work :P

I have tried with CLI tools like "wget", "hosts", "ping", "telnet" and so on and the site loads ok. Even I have used Dillo (damn simple web browser) and the site loads ok also.

Things I've tried so far: - Suggestions at https://support.mozilla.org/en-US/kb/firefox-cant-load-websites-other-browsers-can - Suggestions at https://support.mozilla.org/en-US/questions/1011327 (similar issue, not exactly the same).

It must be a silly thing but I'm out of options now. Perhaps anybody has faced to this situation in the past: any suggestion on this issue?.

Thanks in advance, Ibon.

Hi, I'm using version 101.0.1 (64 bit) for Ubuntu 22.04. When I open a link of a pdf file, the file is displayed in the built-in viewer, since I chose "Open in Firefox" in my settings. But then if I click the download icon nothing happens. If I click the print icon and choose "print to pdf" in the popup, then clicking on "save" does nothing and I have to click "cancel" to dismiss the popup.

Actually there is no way to save a pdf file but setting PDF app to "Ask always" and then open it with "System handler", but then the file is saved into the default download folder, even though I selected the checkbox "Always ask me where to save files" in my settings.

EDIT: the issue was solved by installing the following packages, as shown in this question :

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

Beginning this afternoon, Firefox 107.0 for Mozilla (OS=Ubuntu 22.04) is preventing me from downloading and opening PDF files. i have to use my Win 10 PC to download PDF files.

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!

I have recently updated to Xubuntu 22 and in the process my firefox was migrated to the snap version. Now firefox is using its own mouse pointer style (smaller pointer, "hand with cuff pointing left" instead of "hand pointing up" over links). I can edit the system style of my mouse pointer, but that does not change the mouse pointer while in Firefox. This seems the same problem like these two questions: - https://support.mozilla.org/en-US/questions/1380997 - https://support.mozilla.org/en-US/questions/1369875

How do I make Firefox use the system settings for the mouse pointer? Or at least how do I change the mouse pointer style/settings for Firefox snap at all?

For reference my Firefox Version is 104.0.2 (64-bit) Mozilla Firefox Snap for Ubuntu. My desktop environment is xfce 4.16.

Thanks, Peter

I'm trying to load a temporary add-on on my browser, but when I click the button "Load temporary add-on", nothing show up.

I tried to look for errors in the console or debugging tool, but nothing. With snap, I removed with the purge option my Firefox and install it again, but the issue still appears.

Some technical details: Ubuntu 22.04 LTS Firefox version 101.0.1 (64-bit) Mozilla Firefox Snap for Ubuntu canonical-002 - 1.0

I am running Unix Ubuntu 22.04 with Firefox 104.0.01 (64 bit). My Canon LBP 6230DW works fine in my word processor and in Chrome, but it does not show up in the Printer destination field when I am in Firefox. The only print option is to "Save as PDF." How do I get the Canon to be a print destination in Firefox?

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.

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.

Hello :)

Firefox 102.0.1 crashes after some Time. Firefox then is unable to switch between Tabs and stuck at the opened Website.

For testing Purpose i start over with a new profile and did not install any Add-ons. The behavior was the same, it crashes after some hours.

My System is Ubuntu Mate (Ubuntu with Mate Desktop) in Version 20.04.

Here has someone the same problem: -> https://bbs.archlinux.org/viewtopic.php?id=277649

Thanks for any suggestions.

I'm using Firefox Version 98.0.2 on Ubuntu 21.10 with Wayland and Gnome 40.4.0. I choose a larger cursor size from Ubuntu's Settings->Accessibility->Cursor Size. However, in Firefox the cursor always displayed in the smallest size.
