Since I bought a new phone, I was trying to login to my account for Firefox on that device too. I was not sure where to find my recovery codes for 2FA, so after a lot of messing around, I've disabled 2FA and was able to login on my new smartphone without it.

Now I'm trying to setup 2FA again, following the steps as described in the Support article: https://support.mozilla.org/en-US/kb/secure-firefox-account-two-step-authentication

However, when I scan the QR code with either Google Authenticator or Authy (which I tried, because I thought Google Authenticator was not returning a working security code), the 2FA setup keeps telling me the code is not right. What am I missing here?

In Google Authenticator I've already tried the "Time correction for codes" setting (my app is in Dutch, so I guess that's what the setting is called), but that also didn't help. I tried logging out and in again on my laptop, also doesn't work.

Any ideas/suggestions?

Firefox not loading and missing VCRUNTIME140_1.dll preventing re-installation. Full message is: 'The code execution cannot proceed because VCRUNTIME140_1.dll was not found. Reinstalling the program may fix this problem.' Tried to install an old version of Firefox (28.0) but this is not upgradeable.

Video playback stutters in Firefox and Firefox Nightly but not in an external player (mpv) or Edge. Hardware acceleration on/off makes no difference. Using the latest Radeon driver 22.11.2. Most noticeable during slow pan like this https://youtube.com/clip/Ugkx7jP_XuVB7i-O6ljGHQ_NjPmEakzvD7yM

The video playback stuttering isn't new but I only stated looking into it now. No idea how long it's been like this. At first I thought it might be caused by running my monitors at true 120Hz and 60Hz instead of a fractional framerate but then the stuttering should be visible on other apps too. Switching to a fractional 60 didn't change anything in Firefox.

Single tab crashes to a black screen

I am running Firefox 107.0.1 (64 bit) on a Dell Inspiron i7 10th gen with 12 GB RAM. Windows Edition Windows 11 Home Version 22H2 Installed on ‎11/‎1/‎2022 OS build 22621.819 Experience Windows Feature Experience Pack 1000.22636.1000.0

Recently have had new issue with websites, like the NYTimes, which run live video embedded in the site. The entire screen will go black and cannot be retrieved. But the system is not down, I can toggle to another application, and then when I go back to the Firefox, I can "save" it by quickly selecting a different tab. If I wait a few seconds, however, the offending tab will crash again. The other symptom is that after this happens, the entire screen in any application seems to be unstable, with transient fuzziness of the fonts, just a for a few seconds, whenever the focus of the screen is moved or changed.

This problem does not occur in "Troubleshoot Mode", but I have gone through all the recommended step by step eliminations of possible plug ins, extensions, Norton, firewalls, refreshes, start up cache clearing, cookie clearing, to no avail. Cannot find discussion of this problem in Support. I do not experience the problem if I run the offending website in Edge. Any suggestions most appreciated, txs!

I am able to login to my account however my "primary password" was breached and changed. I am now unable to login to the browser and use my Bookmarks.

You'll know it has been breached because I have only used on password since I began using FireFox. As of January 9th, 2023 it has been changed to something new.

How can this "primary password" be removed or reset?

Just the last month or so, when I preview an attachment then download it, I find that my Yahoo email session has been closed.

A recent Firefox update made it easy for me to re-open the mail session but it never returns to the email I had open at the time.

Is this a Yahoo issue or a Firefox issue? And more importantly, how do I stop it happening?

I notice similar questions last year had no response

Private window icons in Win 10 doesn't work as expected with Profiles

I have shortcuts to launch Firefox in two ways, one with no commands and one with the following command: -P "Personal" --no-remote This used to show two separate Firefox icons on the taskbar. Firefox windows opened in each profile would be grouped with the same profile and kept separate from other profiles. With the latest update I still have two icons, the Default profile has a Firefox icon and the 'Personal' profile has a private browsing icon. Even though there are no private windows open. According to latest updates, if I open private windows then they should be grouped with their own icon. However, whether I have Default or Personal profile windows open, Private windows are grouped with their standard browsing windows.

This is on Win 10, Firefox 107.0.1

Any ideas how to fix this? Ideally I would have the standard Firefox icon on both profiles then, to conform with the private window separation update, my private windows would be separated from the standard windows but also from different profiles.

It takes me back to the login screen which prompts me for my account details. 6. I enter my login details. 7. I get a JSON error message {"error":"ERROR_DURING_DEVICE_REVOKE","errorDescription":"ERROR_DURING_DEVICE_REVOKE"} on what looks like a Firefox diagnostic screen; the "headers" tab shows this:

8. I click the refresh/reload button 9. There's an "Accept cookies?" pop-up; I click reject all cookies. 10. The "Add trusted device" screen lets me choose a phone number to receive a one-time password. 11. There's an "Accept cookies?" pop-up; I click reject all cookies. 12. I receive the one-time password via text and enter it. 13. There's an "Accept cookies?" pop-up and (beneath it) a "Securing your browser ... please wait..." screen, which eventually is replaced by the "Your accounts screen". 14. I click reject all cookies and FINALLY I'm able to view my nsandi.com account details !

So there seems to be two issues i. The need to enter my login details twice, and then reload the page on receiving JSON "ERROR_DURING_DEVICE_REVOKE" ii. The fact that every step along the way, I get the same "Accept cookies?" pop up - surely having told it my cookie preferences it shouldn't be asking again and again and again...

Because the login dialogue takes me to three different URLs: https://auth.nsandi.com https://secure.nsandi.com https://www.nsandi.com ... I wondered if Firefox's "Enhanced Tracking Protection" was interfering with communication between them (via the browser, during the login process). So I added all three to "Exceptions for enhanced tracking protection". But that didn't make any difference.

My work-around is to login using the Microsoft Edge browser. But it's a pain to having to remember to use my non-preferred/non-default browser for this one account.

A msg. suddenly appeared at the top of my ff general settings page saying "your organization is managing your browser". Upon clicking on it it appears that Chrome has taken over most of my ff settings and disabled some of them. I have NO organization; I am retired and have a personal computer that only I use for personal things. I have run numerous anti malware programs that have found nothing. I have restored the computer to a much earlier time. I chose Firefox, NOT Chrome. Please help me get rid of this. And please don't assume I have knowledge as I am old and not very computer literate so if you could use simple terms I can understand that would be much appreciated. If no help, what can I do next to get some. Thank you I am using Windows 7 home premium on an older Dell business machine.

Hi I'm wondering if anyone else has this problem. I've set it so that FF asks me if I want to close all tabs when I close a window or exit. This is to restore pages when I restart next. What I've noticed is, this number of tabs in the question only keeps increasing -for example, if I have 50 tabs open, close 10 of them during a browsing session and open 20 more, when I go to exit, it'll ask me if I want to close 80 tabs. And when I start up FF next time, that number 80 just keeps increasing when I open/close tabs. It doesn't seem to be refreshing the 'tab memory'. There needs to be a button perhaps that purges that tab cache and takes a fresh 'reading' of all current tabs open and updating the total number.

Anyone else experiencing this? Thanks

I'm having an issue in which the picture-in-picture pop-out won't stay maximized. It's been happening for a while. I will maximize it on one monitor while I work on another, and it will restore itself to the last size I had it periodically. Usually, if I don't maximize it again, it will change sizes again, a few seconds later, shrinking down to about a 480p sized window.

There's no rhyme or reason for when it happens. I could be in a different FF tab or window, or in a different program, or just sitting there not doing anything, and it can happen. Sometimes, it happens multiple times in a short period of time (just now, it restored itself 7 times in a row, less than 30 seconds apart). It never happens when the video is not playing, however.

This only started a couple months ago, but it got noticeably worse in the past week or so. Does anyone know why this might be happening?

Computer specs are: Windows 10, 10.0.19043, Intel core i5-7500 CPU, ASRock B250 Gaming K4 motherboard, 16GB RAM @ 2133Mhz, NVidia GeForce GTX 1070 GPU, Samsung SSD 860 EVO 1TB.
