Firefox Support Forum

I have 2-Step verification on Gmail. When I go to log in I get this: Insert your security Key into the USB. I cancel out of it and get this: Your phone can’t locate your device. Move your phone closer to the device where you’re signing in, and then try again. I "Try another way" and I try to get a "one-time security code" and it forwards me to a website where the cycle begins again. If I try "Auto-recovery" it sends me to google. I can access Gmail on the same machine via Chrome, but would rather not. I can also get it on Firefox on my phone.

I did recently turn on two-step and it asked if I wanted a key, and I thought it might mean Google Authentication, I think it meant a USB key.

Any thoughts? I rather not give up Firefox.

Preamble: for most of the day I have Firefox open with several tabs. For a specific project I want Firefox open with one tab showing a specific webpage. At the same time I don't want to delete the existing tabs in the existing instance of Firefox - I want to keep them running in the background. Question: how do I create a desktop shortcut which opens a new single instance of Firefox with a single tab showing a specific URL ?

Whenever I use the searchbar in the bookmarks manager, it always searches all of my bookmarks, but sometimes I might only want to search for that query within a specific folder. Is there any way to limit a bookmarks search to only a specific folder rather than the entirety of my bookmarks?

3 days ago I closed my main Firefox Windowby accident, while other windows were open. To restore, I just used the normal "recently closed windows" option and reopened my windows. Immediatly, all my tabs that were assigned to "Containers" were duplicated, and I lost the "Simple Tab Groups" order. For each tab on a container, a second was created without an assigned container. Fine, i thought, just closed 130 tabs that were unassigned, and moved them to the right Groups again. Next day, i open firefox, same thing. All tabs duplicated (but now on the proper groups). Closed 130 duplicated tabs and moved on. But I can't spend 5 minutes each day doing it! Testing more, I realized that every time I close and reopen Firefox, all the tabs assigned to a Container get a copy. If i close and reopen firefox 10 times, i will get 10 copies of all tabs, with no assigned containers to them, ending up with 1300 unnecessary tabs.

I just cant figure out how to fix it. Any advice?

Running WIN10. I have used FF w Google for about 20 years, and always had new searches open in same window, new tab. Following recent refresh of FF, that seems to be not possible. Links open in new tab, but not searches. In about:config the browser.search.openintab setting is True

I have closed and reopened FF, and closed and reopened WIN10.

What might be over-riding this? Many thanks!

Hi all

I'm a happy user of FF but have started to see issues with JavaScript (error message: You need to enable JavaScript to run this app.). I do the about:config correction and it sometimes works, but now the error is spreading to involve other pages - a page worked yesterday doesn't work today.

Is it just me?

I previously had the NoScript extension. I disabled it in preferences and restarted Firefox. It seems like one of these moz-extension:// windows were open at the time, so when I try to launch Firefox, it tries to re-create moz-extensions:// windows and dies.

I can’t start Firefox. I can’t start Firefox in --safe-mode. I’m happy to provide any debug info needed.

Dear Community,

I've been struggling with a very peculiar error with my Firefox in the last couple of weeks that I haven't managed to find a solution for. It's kinda disturbing and makes me want to stop using the whole thing, even though I'm a big fan of Firefox.

1.) The first sign of the error is the browser suddenly becoming partially unresponsive. The UI still works - as in, you can scroll down/up on open pages, navigate through menus, open/close tabs, etc. but no HTML content is loaded JS isn't running. First I thought this was just bad connection, but I had a stable internet connection and other browsers would load the same pages. 2.) At this point, when I try to close the whole app and restart it, I get a message that the browser is already running. The dialogue box also offers to force restart the app, which doesn't work (it stops the process but doesn't restart it, so I still have to manually launch the app). 3.) After manually launching after failed force restart, I'm getting another error message saying that I'm using an "old version of Firefox", due to which my old profile "might not work". I can either exit the app or create a new profile. From a new profile I can load profile manager but I'm unable to launch the other profile. However, indeed there is an app update pending. 4.) After the update is installed, the browser launches the new profile and and then from the profile manager I'm able to load the other profile, set is up as standard and remove all other profiles. After this step, all seems to be normal and Firefox keeps working without any issues until a next update is found, but then the whole issue starts from point 1.

First time I suspected that the profile is corrupted, so I deleted it and resynced the settings from my Firefox Account, but this has not helped, so I fully removed Firefox with all the data stored on the local drives and reinstalled it. Then the latest version was installed and the profile worked, so I presumed the issue to be resolved until a new update came. In the last month there's been at least 3-4 updates, all triggering this very peculiar issue issue. I was thinking this might be known so the devs would release a fix soon, but I couldn't find the same issue mentioned, so now I'm suspecting one of the add-ons acting up. However, since the issue only reproducible when an update is released, it would somewhat complicated and time-consuming to deduct which one is causing the error. Hence, asking question here as I'm wondering if anyone had encountered anything similar or could suggest any further steps to fix the error.

I'm using 104.0.2 (64-bit) and following add-ons:

I haven't captured the exact error messages but I'm happy to do if that sheds some further light on the issue (would have to wait until next update for the issue to happen though). Any tips would be appreciated.

I have recently installed Linux Mint and it came with Firefox out of the box, and I decided to try it out, but I can't, for the life of me find a way to transfer my Opera passwords there. I do have Opera installed right now.

HELLO very small cursor on Firefox windows (on all other windows the cursor size is normal) via snap after upgrading to ubuntu 22.04.1 LTS. how can i change it? Thank you

when i open a new tab i want it to go to https://uk.yahoo.com/. how can i achieve this please, as loosing the will to live. Many Thanks Steve

I'm on Ubuntu 22.04 which is using the snap package of Firefox.

It seems that I cannot open local files in the /tmp directory. When I place a test.html file there and run `firefox /tmp/test.html`, it returns a file not found error. Why?

I don't have the problem with files in my home directory.

Dear All:

Suddenly FF starts but shows only a new tab without any content. I can fill in a URL but no reaction. Settings doesn't open. Close tab through X Restart FF. no new tab but message: FF is already running but is not responding. The old FF process must be closed to open in a new window. Click to close. a new empty tab pops up without starting FF manually. Close through X Restart brings the same message as above - no window. Have to end FF in Task Manager.

Uninstalled and reinstalled three times - no change.

I'm using Windows 10 and Avast One, Firewall checked - is open for FF.

I appreciate your comments and help. Best wishes Henning

When I try to log into Google I get this message:

I am using Firefox 91.13.0 ESR (64bit). I have been using the 91.x ESR releases for a while now and this is a new problem that I never had before.

Release after release Firefox is adding more shortcuts, which is nice, but it also interferes with shortcuts people use to enable/disable extensions.

Is there a way to completely disable a given Firefox shorcut without having to rebuild it? Ideally Firefox should have a friendly way to change that (UI or config file), but I accept editing binaries files.

Also, why extensions with shortcuts like Shift+D are treated as invalid and get removed?

Hello, I need help, it is not possible to open Firefox. After opening, the window closes itself again, a new profile was created, but the problem is still there. I am very unhappy about this. I didn't load a new extension, didn't use new antivirus software. Firefox has already been uninstalled and reinstalled. The problem is not solved. I've also cleaned Firefox a few times, but the problem still persists. There are no crash reports as Firefox just closes and doesn't crash. I can start safe mode. I am sending the Troubleshooting information.

Thanks for your help, Firefox is the best browser! Greetings Silke

Occasionally, when I am watching a video on Youtube or Twitch, the video will glitch and cause the browser to go completely white. On Youtube, there will be a small visual glitch and on Twitch, the video will crash and need to be reloaded, but otherwise nothing else happens.
