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"

Hi there,

After a Firefox Refresh, one site I used to access everyday does not accept my user Id/password anymore. The site did not return any warning message like wrong password. It just doesn't go trough when I hit 'enter'.

The same user/pw is still working well in Chrome. I asked for help on the site I could not access, but they have no issues like mine, and his system is regularly on.

I have already cleared all my history, cookies, everything. I have installed Firefox again. Nothing.

Any idea? Thanks

Hi there , I am interested to know if Mozilla support group is aware of the problem Microsoft update KB4474419 causes? I am running widows 7 sp1. I installed the update as you mentioned in your Firefox 100 release notes. After reboot , I got a beep and a black screen - win 7 won't start. I had to find a way to delete the update so I could boot my system back. I asked few of my colleagues that use the same OS and they experienced the exact same problem. Surfing the web , makes it quite clear - this update is faulty and not compatible with win 7 as Microsoft claims. I would like to get a straight answer - can I update my FF99 to FF100 , without the notorious KB4474419 , or , as of FF100 , win7 sp1 is no longer applicable to Firefox ? Thanks. look4

Using the 'Chat' facility on the HSBC website

Hi,

Let me start with two points: (a) this is the first time that I've used this site, so if I do anything wrong please just tell me and I won't do it again, and, (b) I'm no technician (I deliberately use Firefox because I believe in Mozilla's business principles, not because I think Firefox is technically superior to other browsers - although I'm quite prepared to believe that it is) but I can follow instructions. OK, so having said that …

I am using the latest version of Firefox [98.0.2 (64-bit)] on a bog standard Dell laptop under Windows 10 [Edition Windows 10 Home, Version 21H2, OS build 19044.1620, Windows Feature Experience Pack 120.2212.4170.0].

I have recently opened an HSBC bank account. If I try to access their UK online banking site (https://www.hsbc.co.uk/) using Firefox (which I should very much prefer to do than with any other browser), it is missing the most important feature of 'Chat' (the only sensible way of talking to HSBC without having to endure a half-hour wait). However, if I access it using any other browser (e.g., Microsoft Edge) the 'Chat' facility is available in the bottom right-hand corner of the screen. Please note that with Firefox I am using a 'container' (called HSBC) - I don't think that Edge has similar facilities.

Can anybody please tell me whether I might have some setting or other (e.g., say something to do with 'pop-ups' which I think that the HSBC's 'Chat' facility uses) set incorrectly?

Thank you and best regards

John

On certain websites I notices I have 'unknown errors' when trying to log in.

Usually this is remedied by either using Chrome or clearing cookies and the cache.

Both of there are inconvenient and result in a great deal of wasted time.

The usual response by these websites is "get Mozilla to fix this".

I'm getting sick of this.

I don't want to switch to Chrome but I will have to if this persists.

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

Hi!

Is there any way to keep an older version of Firefox without its getting upgraded all the time? Version 99 only has a small header at the top, so there is still space on my screen to see the website I'm trying to see. The newer versions (100 and newer) take up too much space on my screen. Every site has its own headers, and so I am left with about an inch of working space. That's really not enough to see anything.

Is there a way to get the security updates without the new look? Is there a Firefox Light version available, with minimal headers and all? I prefer Firefox, and would love to keep it. Having to reinstall it (to get the older version back) several times a week is not good.

Any help would be appreciated. Thanks very much!

It appears web sites can track my activity on their site. How do I make it so a given web site can't track me? Does Firefox have a setting that makes it more difficult to track me on a given web site? I've seen where a VPN, not sure what that is, can be of big help. How do I initiate a VPN and are there free VPN's? When I visit this particular site it states, "from your site login activity" and goes on from there what they want to do. How do I make it more difficult for a web site to be able to track my log in activity? Will a VPN solve this problem? Or, does Firefox have various accessories that can do the same thing? I know deleting cookies with this particular site does not solve the issue for me. Can someone help? Thank you.

My google drive keeps disconnecting, and google drive/google docs links are not working. I have attached a screenshot of the new tab page when I copy paste a google sheets document URL into the search bar and hit enter. After the reloading icon animates, I stay on the new tab page and the url just sits there. The debug console shows 1 GET request that is timed out (picture also attached).

I can fix the issue by completely closing all firefox windows and opening again, but it will disconnect me after some minutes.

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!

Uploading photos to Meetup

This sounds like it's a Meetup problem, and in fact it may be, but now I am having doubts.

The problem is that I can't upload photos to a Meetup event. (This will mostly just be a problem for Meetup organizers.) When I click on "Save photo", nothing happens. No error message, nothing. It's as if the "Save Photo" button has been disabled. Firefox is my browser while I access Meetup.com, and I have the latest and greatest version of Firefox.

I contacted Meetup and they haven't been able to solve the problem; they suggested that I clear my cache and my cookies and try again, but I get the same result. HOWEVER, when I go into Microsoft Edge, I can upload photos with no problem. So I have a work-around: use Microsoft Edge to upload photos. So my question to you centers around: why does this work perfectly in Microsoft Edge, but it doesn't in the latest version of Firefox?

To test the possibility that it's a bug on my personal desktop computer, I went to the public library and tried the same experiment, with the same result. So I don't think it's problem with my personal desktop computer.

One other piece of information: the exact same thing happens (failure to update photo, that is) when I have the photo open in another application (Photoshop), even if I try to "save photo" to Meetup in Microsoft Edge. Then when I close the other application (Photoshop in this case), Microsoft Edge lets me "save photo."

I know that Firefox really doesn't want me to try to revert to a previous version, and it makes me nervous too, but I am suspecting that something in the latest Firefox version actually introduced a problem. (Or maybe triggered a Meetup bug of some sort; I still haven't located the problem.) I've been on Meetup.com for years, I've had Firefox for years, they've worked together to upload photos in the past for years.

If you want to get into the details, below, for what it is worth, is my initial question to the Meetup support people (with whom I am still in a conversation).

- - - - - - - -

I can't upload a photo for my event. In fact, I cannot upload a photo for any event at all. I deleted a couple of photos and an album because maybe our group had too many, but that didn't work. I can't even upload a photo that I had previously uploaded to a different event, so I don't think that the problem is with the photo itself.

Here's what happens. 1. Edit the draft of my meetup. 2. Click on "upload photo." The photo is 1827 x 1009 pixels, total size 63 KB. 3. I click on "Upload photo", then in "add photo" I click on "upload photo" again. I browse for the photo and select it. 4. The "crop your photo" screen appears, with the selected photo in it. It's already the size I want, so I click on "Save Photo".(Cropping doesn't help either.) 5. Nothing happens. No error message, nothing. The only think I can click on is "cancel," which takes me out to the previous screen. - - - - - -
