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 had been using Firefox browser for awhile, but because of playback performance issue, I have to using another browser just for video playing, especially for 4K video.

Compared to Edge, Firefox seems taking more resources to playback the YouTube video and more heat. When look at the Task Manager, the Video Processing is 0%, and GPU is running significantly more resources on '3D'.

Recent Firefox Update breaks multiple Login Portals on websites

After the most recent update to the browser, I am no longer able to successfully login to many websites. Example for me include: Xcel Energy, Aol Mail, my local City Utility website and no doubt others I have yet to discover.

I know this is a browser dependent issue because Google Chrome is still able to access these sites just fine, but after the latest update to Firefox it no longer can.

It's able to load the login page and the site, but login in specifically returns either an error that shows on the webpage, or the URL displays some form of error code. Or in AOLs case it simply says "Uh oh. Looks like something went wrong. Please try again later." with a length authorization error code in the URL.

Any help with this would be appreciated. I've cleared Cookies, Cache, Active Logins and every other History Clearing option set to "Everything" as the length of time back to clean-up.

Like I said, this is a Firefox dependent issue due to Chrome accessing these sites just fine. I'd rather stick with Firefox over moving to Chrome but if no one can solve this problem then I guess it'll finally be time to ditch Firefox sadly, even though I've been using it since the early 2010s.

Hi everyone,

Last Saturday, I was able to sign in to Firefox Add-Ons Firefox Add-Ons and submit a pre-release of an add-on I'm working on. But today, I'm being forced to enable 2FA to simply log in to the site. I don't want to enable 2FA, I just don't need it. Can someone explain me why is this happening ? Can I just log in and submit my add-on's update ?

I've tried to sign in two different MacBooks (M1 12.1 and Yosemite 10.10.5), using two different Firefox versions (99.0.1 and 78.15.0esr). Also, I haven't enabled 2FA in my personal account.

Thanks in advance.

Hello,

I noticed that a setting on the about:config page was removed: the "security.csp.enable" setting. I was using this setting to disable CSP to be able to load local JS scripts on some non-locally hosted sites, for debugging and development, work related purposes.

Was this setting really removed? Is there a way to disable CSP on Firefox on the latest version?

Thanks! Gabriel.

Is there a way that I can express my trouble using gmail in Firefox, but have the gmail accounts work fine in Chrome and Edge? In Firefox, my gmail accounts show me as LOGGED OUT, when they are supposed to be logged in, and Firefox will not allow me to log into them again. I have 3 gmail accounts, [edited email from public] @gmail.com is my most active, but none will work in Firefox anymore, but in other browsers, they work fine. All other tabs I open in Firefox, works fine, so it's only my gmail accounts, that has trouble in Firefox. What can I do to correct this?

Thanks

The styles look astonishingly wrong, I really think it is a problem on my end, but cant figure out how to fix it, as you can see in the pictures, text is incorrectly sized and/or justified, color gradients are also weird looking, as well as sizing of many elements and tons of other things.

I have tried to completely remove Firefox from my system and reinstalling it, that did not seem to fix it. The reason I think is is a problem of mine is because i was playing with fonts (emojis weren't working on my system,not on Firefox tho, now they are in both)

I don't think the things i did with the fonts did anything to Firefox, since this problem only showed up on Firefox, but since the problem arrived just after a reboot while I was installing and removing the fonts, I think its important to mention.

To sum up I think the problem comes from my local configuration of Firefox, I probably did not delete it all before reinstalling, I am running (Arch btw) a current version of EndevourOS.

Hi.

I need to print out my saved passwords. I have no cellphone to access, just my laptop and printer. I only use Firefox and no other browser. If my laptop gets hacked or breaks down, then I need to use someone else's computer to access my passwords in an emergency, and can't access my passwords to do so...so printing them out periodically is the smartest thing I can think of.

Help, anyone? This is pretty important to me. Thank you!

Hello,

I have had a few websites not work properly with Firefox and have needed to open my backup browser (Avast Secure Browser) to use those websites.

Right now it is FedEx that comes to mind again as I kept checking for tracking of packages shipped to me since receiving the tracking info. I queries consistently returned the error message "Unfortunately we are unable to retrieve your tracking results at this time. Please try again later."

Thinking maybe the website was having issues or maintenance (and forgetting I had the same issue with FedEx website the last time I tried tracking there in Firefox), I kept "trying again later".

Then I opened my Avast browser and pasted the same url there and, sure enough, received this report on the display:

Travel History Date or Time City & State Status Monday, April 18, 2022 9:47 PM SPARROWS POINT, MD Departed FedEx location Sunday, April 17, 2022 1:49 PM Shipment information sent to FedEx

I have tried disabling the extension NoScript as well as turning off the "Enhanced tracking protection" and allowing permissions for the FedEx site with no improvement.

I copied and pasted the RAW data as well as the text version from the "about:support" page to send you.

Any suggestions to fix this?

Thank you, Keith McNabb

I've noticed that some websites will endlessly spam the console (in developer tools) with rubbish, and I would like to be able to block that from happening. I'm ignorant about this sort of stuff in general, and it confuses me how a website can even access my browser's console to begin with.

The latest example I came across which caused me to finally ask about it, was some strange JavaScript spam with some kind of < div > (had to edit this with spaces to show it in the post) structure containing over a thousand characters. This entire thing gets spammed in the console at a rate of a few every second. I recorded a short gif of it, which imgur seems to have converted into a video: https://i.imgur.com/dosMZjo.mp4

Hi there. I'm in the process of switching from Chrome and I want to import my passwords.

I first tried the 'import from Chrome' option - it says it's successful, but nothing has actually been added. Same result after several attempts.

I then tried the csv route. I found out I had to change the config settings, so I did just that, but the 'import CSV' option still isn't showing even after a reset.

So now I'm at a dead end. Any bright ideas please? TIA!

FYI I'm using Firefox 99.0.1

Every time I enter a link to a google service, I see a notice that says "Your should be redirected in a moment..." and then I get redirected to the Stanford University website (https://pass.stanford.edu/signin.html). It is not a specific website redirecting me, but rather some algorithm is detecting a google link and sending me to Stanford University instead . For instance, if I paste in a link to a particular location in Google Maps, I will end up at Stanford instead. I have no idea how to fix this, but it makes me avoid Firefox and use Chrome because Chrome does not redirect. I would rather use Firefox.

I'm downloading a lot of images, and every time I do so a popup box appears showing the most recent five downloads and a button to show all downloads, It covers some of the icons I use for downloading images which is frustrating. If I right click on any of the downloads one of the options is to Clear Preview Panel, so I assumed it was called Preview Panel, but help does not know about that and I can't find how to stop it coming up (it used not to until I did something, I don't know what) It's driving me crazy.
