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:

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'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.

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

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.

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.

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.

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.

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, 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 have Firefox 107.0b5 (64-bits) Snap for Ubuntu canonical-002 - 1.0 I use Ubuntu Mainline to update to newer kernels. Never had any problem doing that. I am now on 5.19.15. But when I upgrade to kernel 6 (which is now at 6.0.5) Firefox tabs crash. Reloading doesn't help. Each new tab I open gives the same crash message. I have to restart to get Firefox going again. So I removed kernel 6 and reverted back to kernel 5.19 and have no problems any more. But question, what is the problem between kernel 6 and firefox? Does anybody else experience this problem?

I have no other problems with kernel 6 with other programs or hardware or whatever, only firefox tabs crash...

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.
