I'm trying to access my federal government account. They want me to verify my identity at verify.id.me. When I reach the point that it wants to see my ugly mug on camera it tells me there is no camera. I've given verify.id.me permission to use the camera in privacy & security. I can record a video with ffmpeg. What have I missed? I don't see any relevant errors in firefox's output. I'm trying in safe mode.

Fix for RangeError: invalid language tag and client-side exceptions in Firefox on Linux

Hi everyone, I was experiencing persistent JavaScript errors in Firefox on Linux when loading certain modern websites (e.g., built with React or Next.js). The browser console showed messages like:

   RangeError: invalid language tag: "chrome://global/locale/intl.properties"

   A client-side exception has occurred (see the browser console for more information)
   React error #418 with minified stack traces

This happened even in Safe Mode, with all extensions disabled, cookies/cache cleared, and Enhanced Tracking Protection off. ✅ Root cause and fix:

Turns out the issue was related to missing or broken locale configuration in Firefox. To fix it:

   Open about:config

   Create a new string entry:

       Name: intl.locale.requested

       Value: en-US (or fr, en-GB, etc. — any valid locale)

   Restart Firefox

After adding this key, all affected pages started working correctly. The invalid "chrome://global/locale/intl.properties" error in intl.accept_languages disappeared as well — it seems that was just a side effect of the missing locale setting. 🔁 Summary:

If you’re seeing RangeError: invalid language tag and React crashes, try adding intl.locale.requested manually. This fixed the issue entirely for me on Linux.

Hope this helps others!

I keep a lot of tabs open (~60) in any particular session - I find it's faster in this way to get back to a site.

About every six months or so, I lose *all* these tabs because of Firefox's inadequate session backup system. It only saves two or three total backups, some of which are completely out of date. But the worst scenario is when (1) some site pops up a new window; (2) I mistakenly close my main window before the new window; (3) I open this new saved window once or twice by accident, causing my 60-tab session backup to be overwritten.

Using a third-party session manager (I have tried all the well-known ones) can mitigate this problem, but doesn't really solve it because the re-opened sessions aren't quite in the same format as Firefox sessions and so lose information. In particular, I often lose each tab's icon as well as metadata for Tree Style Tab.

Could Mozilla please consider a more robust session backup system for Firefox? All it would take (I think) is to allow the user to choose the total number of backup sessions and the frequency at which a new session is added. Thank you!

I cannot install English GB dictionary for my spell checker. When I click add dictionaries it takes me to a page where I can select Englsih GB as one of the dictionaries available in my locale. It then takes me to the info and remove page for the dictionary but there is no option to install and no pop up to start the download appears.

I visit antiwar.com, read an article, read comments, then try to give a thumbs up on a comment I agree with. I click on the Disqus box to log in, but the vote count doesn't go up. I've already tried setting NoScript to allow everything on that site, but nothing changes. I've already tried uninstalling Firefox then reinstalling it on my Debian based Linux computer, but the settings are remembered. I have also tried to refresh Firefox like this page says: https://support.mozilla.org/en-US/kb/refresh-firefox-reset-add-ons-and-settings But the instructions are apparently for an older version of the browser because step number 1: Click the menu button Fx89menuButton, click Help and select More Troubleshooting Information. does not lead to what is shown on step 2. No "Refresh Firefox" boxes appear.

Is there some setting I need to change in about-config?

So when i visit a website that relies on changing local files, sometimes its the correct thing and others its not. I assume since im on linux it might be installing though a snap and something else. Any help would be appreciated.

Find out why and fix issue with pages not loading. Get a white blank page after a search inquiry on some web sites, (lowes.com),

Alright, so I have a bunch of sites on the bookmark that I have. Sometimes when I open one of them, the tab automatically closes, this also happens when I search something in the address bar. The error isn't critical but it just bugs me, yknow? I am using Firefox on Linux MInt 21.1 Vera, Firefox 115.0.2 (64-bit). Thanks for answering my question

I use Firefox for many years, no problems. But recently I got fake websites with www.maccabi4u.co.il and PayPal. What is wrong? I downloaded Chrome and it does not happen.

I'm struggling to get Firefox to use `http` instead of `https` when I'm doing development on my laptop. Playing with the `HTTPS-only` in the settings didn't make difference. With enable or not. I tried to add my `localhost` to exception list, but Firefox still tries to use `https.`

I understand the security concern from Firefox team, but if I'm trying to load by typing `http,` I would appreciate if Firefox gave me a benefit of doubt that I know what I'm doing. Maybe I could disable this feature temporarily. Why force `https` on `localhost`?

Please allow us some flexibility.

I would like to enable picture-in-picture without constantly having a popup for it anytime my cursor goes onto the video screen. You could just put a button somewhere out of the way. It's so annoying I have to just disable it, and that's not right. Nobody needs popups of any kind for anything ever. It's the same as an ad.

I wish to backup my password file and tried to follow: https://support.mozilla.org/gl/questions/1189644

I could not work it out and suspect the instructions refer to a version of Firefox I'm not using. My version is 68.12.0esr.

Thanks

I want to switch off (cancel) password save for one website. I have followed the recommended procedure and re-started Firefox, but it still saves the password after I do that. This is one set of instructions I tried following, without success:

Hi there,

I've been using firefox as my main browser and I've created a account and using it all the time for syncing the settings, bookmarks, logins, extensions etc.

BUT due to some unwanted (really irritating) search suggestion were being shown to me by firefox, I had to uninstall firefox from my system.

• • Throughout the process, I'd kept syncing ON always!!

But when I installed firefox again and after loggedin, I'm syncing everything but this is restoring (syncing) very old data which doesn't have my latest bookmarks, extenstions & saved logins!!

How DO I get my all data???

URGENT PLEASE!! THANK YOU

• • Note : I'm using default "Firefox-ESR" in Kali linux 2022

Hello,

Starting Firefox 97, opening a file involves downloading it the same way as if I choose to save it. It results in both Download folder and downloads list in the browser being polluted with a million of files I only wanted to open once with a specific app (pdfs, xls, m3u etc.).

Previously Firefox was using a hidden internal folder for saving such files and deleting them later, so Open In App really meant "open, do not save locally". Now any option just means "Save the file to the Download folder and let it be there forever".

How can I fix this unsuccessful UX decision apart from downgrading to an older version?

Thank you.

P.S. "If you dislike new features in the latest version of Firefox, your first reaction might be to go back to the previous version. Rather than downgrading, try getting used to the new features..." is probably the worst suggestion you can possibly give to someone with their workflow broken by a sudden update they can't decline with a feature they never asked for.
