Firefox Support Forum

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"

Using Firefox version 99.0 (64bit). When I click "Bookmarks / Manage Bookmarks, the listing defaults to the "Other Bookmarks" folder. I would like it to default to the "Bookmarks Menu" folder. How do I make it do that?

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

Looking for free border designs, and have found the add-on easy search tool required for most of them. Their web site has the add-on for Firefox, but how safe is it? Thanks.

MacOS Monterey 12.3.1 FF 99.0.1 Have tried clearing Cache, Cookies, Troubleshoot mode.

Google Maps > Search > Share > Embed a Map, the map to be embedded is not displayed (likewise when embed is pasted into Wordpress page, for example)

While same procedure in Safari or Brave works as expected (map to be embedded is displayed in Google maps and embed code displays map in webpage using Brave or Safari).

From the Google Maps page > share > Embed a map > right click This Frame > Open in new tab And then looking in the Console. There are a few other ignored errors but then this...

Loading failed for the <script> with source “https://maps.googleapis.com/maps/api/js?client=google-maps-embed&paint_origin=&libraries=geometry,search&v=3.exp&language=en&region=us&callback=onApiLoad”.

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.

Hello! I think I have tried EVERYTHING to get Firefox to stop crashing in the past 6 months. Today I am so frustrtated. Can anyone point me in the right direct. (and yes this happens with a fresh install, disabled add-ons, safe mode, yadda yadda yadda

ADDITIONAL COMMENT: why don't you include a date on these posting? a lot of wasted time on old posts? and also need a 'Preview' on these before posting?

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!

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 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

Amazon 'Look Inside' pop-up does not work with FF as I've configured FF. Iv'e included a screen snip.

I've unchecked block pop-ups but still the 'Look Inside' doesn't work.

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.

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!

Each time Firefox updates, the email client changes to the outlook default. The last 2-3 updates, mailto does not appear on the file,settings,applications menu. Nor will it populate if I type it in. I have tried every instruction to no avail. I am a long-time firefox user, non-techie and it is discouraging when things disappear with each update lately. Would appreciate any suggestions. Thanks

This bug occurs very randomly, but it seems there have few things in common.

- Occurring on domain level, one domain at once. For example, if Youtube.com stuck, any sub address including each video page is not loaded. Other website and whole browser works fine. - Other program on same PC is not affected, too. - Which page is stop loading is completely random. It might be happen only on a popular, feature-rich site like amazon, google, but not sure. - The timing is also random. Maybe after waking PC up from sleep, but not sure. Frequency of occurrence is once every 1~5 days. - The workaround without restarting browser is 1.)switching to other container tabs(strangely), 2.)opening website on private window. Disabling all the addon manually didn't help.

Since it's randomness, I didn't have any logs about this issue.

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.

When I go to download a ZIP file, it will always attempt to download the file directly rather than letting me open it with WinRAR. When I go into the browser settings I see that some other file types have options to choose how they're handled, but there's no entry for ZIP files. I've tried refreshing my Firefox install and yet the issue still persists.

I used to have this option before I reinstalled Windows a while back (where I kept my files but not programs). I don't know for sure that that's what caused this to start, but the timing would line up.

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?
