When I click on the grey Last Pass icon, a "set preferences" screen is shown. The strictly necessary box is selected and I cannot change it. The Voluntary data collection box is clickable but does not make any difference if it is checked or unchecked. The screen is locked, no matter what I click or unclick. The only thing that I can do is to click the grey LP icon which closes the window.

On two other very similar computers, when the grey icon is clicked, I can search for passwords, alerts, account, etc. Why does the icon work on this computer. I've deleted the addin, deleted Firefox and reloaded several times.

Thank you

There was an error when downloading files with the browser, indicating that there was a problem with the file directory. The download failed, and changing the file directory was still ineffective. Then, it resulted in a situation where no web pages could be opened, as if the network was disconnected. After closing the browser and reopening it, it returned to normal, but the download still could not be used. This problem has existed since versions 115.24 and 115.25.

I use scoop to install firefox. then i changed the default profile to the Scoop profile. Then i tried to log in the mozilla account but it keep saying that it cannot continue because cookies or localstore are disabled. Then i checked the about:support page like i said in the titile, many configs are blank. Maybe some problems with the profile i guess. I also opened a issue in Scoop githup repo, they cant reproduce my problem. Where could go wrong? Any help would be appreciate!

And this is the issue i post on github https://github.com/ScoopInstaller/Extras/issues/15770

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've recently swapped to Firefox from Chrome and I've noticed a huge hindrance.

I use a chatroom website and when I swap to the tab and begin to type, the first letter is randomly eaten/won't be entered into the text field.

For instance I was typing the word "What" and the text field only displayed "hat". Or when typing "Either" only "ither" appeared.

I thought this may have been related to a hardware acceleration issue but both settings did not work. So I started to look at Hotkeys but none of them should be interfering.

Some others have stated they have this issue too and I've been unable to find any solution. Any help?

I have a MV3 extension I created that has a popup and data that is stored in sessionstorage and extension storage.

When I use the extension in a private window it does not work because data does not persist between each time I open and close the popup.

This causes problems, for example you have I have to login each time I open the popup, instead of the auth status persisting. It works fine in a normal window though.

Is there anything I can do that allows data for an extension running in an inPrivate window to persist. (Maybe some additional manifest code / changing the browser config)

Hello,

Steps to reproduce: 1) have settings above 2) navigate to https://store.steampowered.com/ 3) view a storefront with a video embed 4) zoom to 180% 5) scroll up and down past the video

According to this article I should be able to activate autofill credit card details in my country https://support.mozilla.org/en-US/kb/credit-card-autofill But the option is no where to be found and in about:config I can see it is restricted to a few countries mine not being one. I can not change the list with countries either, actually I can not change anything nor search in about:config. I am running Firefox 140.0.4 (64-bit) EDIT I made a a master password, which then made it possible for me to edit in about:config. I added my country to the extension and now I can activate it.

How can I open an ad on a one-time basis, as if there were an option when right-clicking?

Sometimes we search for something we want to buy. The ad is near the top of the search results and seems to be worth investigating.

But we can't open the ad. Our wonderful ad blocker is, like our guard dog, too zealous sometimes protecting us.

The answer I'm looking for is NOT to go into Settings, etc. That's swatting a fly with a sledge hammer.

I lost everything in a tragic housefire recently and I cannot remember the exact username I used for my Mozilla Account. Of course, this means I have also lost years of valuable Favorites and Passwords and Logins.

Is there anyway to find out what my login name was?
