Hello, I have an issue with activating 2fa on my account. I scanned the QR code using Google Authenticator but when i try to use the code i got from the authenticator, it says "incorrect code" even though it's correct. I tried many times and it keeps happening. I tried entering the authenticator key manually but the result is the same. Can you help me?

I have used Firefox for years. It is updated regularly. In recent years I have experienced non-obvious problems where the browser either will not obey a command, or produces an unreasonable response which is not easy to spot. Latest example: I am trying to fill in a contact form, and when I try and submit, the form displays "Enter a number". This is normal for a contact form if you have missed something, but in this case, there is no field for a 'number'. I try re entering various things. I try their chatbot. I am just about to phone when I think 'try another browser.' I try another browser. It works straight away. This happens too often now, about once every couple of months. Occasionally rebooting helps, but usually it doesn't. OS is Windows 10 on a desktop. I do tend to keep a lot of tabs open, but I always have. I don't actually want to change my browser. Any advice appreciated.

Hi, my Firefox has the Parent process Browser Console pop-up when open Firefox after booting Windows. I used to use Firefox as my default browser with Ubuntu OS years ago, when I changed from Ubuntu to Windows with Firefox as my default browser, with the same account Firefox logged into, the Browser Console started to pop-up every time I open Firefox after booting Windows.

On the Console windows, there always an error showing. How do I resolve these errors. (Not the same errors everytime).

Thanks for reading. Sincerely.

Hello, I have been a Edge user for a while now, but due to privacy concerns, I have decided to switch back to Firefox. I do realize that Bing Chat Mode isn't really the most private search out there, but I have grown increasingly dependent on it. I came across this article which asked me to general.useragent.override to string Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/111.0.0.0 Safari/537.36 Edg/111.0.100.0 and this works.

But I want to know if this really is the safest way to use the Bing Chat Mode on Firefox.

Thank you for your help!

Hello! I recently switched OS from Windows to Debian, and at the same time I also switched browsers from Google Chrome to Firefox. Everything works great except for video playback.

When playing most videos, the audio will continue but the video will freeze when I skip backwards, both in regular and fullscreen mode. Skipping forward does not seem to cause an issue. This occurs on every video I’ve tested, except for WEBM videos and YouTube which both play flawlessly.

From a quick Google search, it seems that YouTube uses a different format called VP9 which my browser seems to handle perfectly. When I try to play videos from my local Jellyfin server in H264 or H265 formats, the issue occurs. The same thing happens to internet videos such as in the Reddit video player.

I have tried to play the same videos in Chromium and never have this issue, with or without hardware acceleration enabled. Every single video I’ve tried plays perfectly in Chromium, and I have zero issues playing video files in media players such as VLC.

I am using Debian 12 with Firefox 114.0.2 installed from Flatpak. My desktop environment is KDE Plasma 5.27.5 and I am using Wayland, with Wayland mode enabled (by adding “MOZ_ENABLE_WAYLAND=1” as an environment variable). I also tried using Firefox before I enabled Wayland mode, so that Firefox was in “Xwayland mode” but I had the same issue before. I have also tried to use XFCE desktop environment with Firefox in X11 mode but, again, same issue.

My GPU is Nvidia GEForce GTX 1660 and I am using the latest available version of Nvidia’s proprietary drivers (525.105.17) which have been working very well for gaming and hosting a Jellyfin server.

The option to enable hardware acceleration was not present in my regular Firefox settings menu but I followed a guide and changed some settings in about:config, thinking that this was going to fix my playback issue. The following settings have been changed:

media.hardware-video-decoding.force-enabled > true gfx.webrender.all > true media.ffmpeg.vaapi.enabled > true

The playback issue is present with or without these settings changed, however. In the graphics section in the about:support page I can see that “Compositing:” shows “WebRender”, which I believe means that hardware acceleration is enabled and working.

I am happy to provide more information if needed. I have spent many hours searching for a solution, but since I’m quite new to both Linux and Firefox I’m not entirely sure what to even search for.

Thank you for reading.

TL;DR: Issue: Skipping backwards in video causes video to freeze while audio continues. OS: Debian 12 with KDE Plasma Wayland (tried XFCE with X11, does not fix issue). Firefox 114.0.2 installed with Flatpak. GPU: Nvidia GeForce 1660 with proprietary drivers version 525.105.17 Hardware accelerated enabled by changing settings in about:config

Hi I use Firefox with a proxy server. I just bought a new laptop. On my old Dell, upon opening firefox, the authentication box for the proxy would pop up, and my username and password would be there saved. All I had to do was click on “sign in” On this new Dell, it will not save these details. Hence, every time I open Firefox I have to manually type in my username and password. I have followed all suggestions, I have made sure “remember password” and “automatic fill in “ boxes are ticked, but this seems to just be for websites. I need it for the Browser/proxy itself, in order to get to be able to browse. Any help would be greatly appreciated. Thanks

I had multiple Firefox browsers and tabs open - simultaneously, and shut off Desktop PC. Whereas, traditional 'restore previous session' option opened most recently opened tab and site, and disregarded all other open tabs and browsers. Whereas, tabs and browsers I wish to open are still on Desktop, although Mozilla will not re-open them as they were (ie. will not re-assemble same order), instead Mozilla tried generating all tabs on one browser and then froze/crashed tyring to re-open all previously open tabs on one broser.

If you can, please assist with a step-by-step instructional - which instructs me on how to re-open all previous tabs which pre-date most recent preceding session (ie. disregard most recent preceding session) and re-open all other tabs which pre-dated most recent preceding session: as respective Desktop PC related-work was un-finished, and so that I might be able to continue at respective Desktop PC related-work.

Thank you. Adam

Whenever I try to play a game on roblox, nothing happens. It doesn't try to open the launcher, a pop up just appears saying "You're moments away from the fun!" or whatever and prompts me to download the launcher even though I already have it. I've tried resetting my cookies and configuring my preferences but nothing's helped. I don't know if this is because of a recent update or because of something I'm doing. Roblox works just fine when I open the launcher by itself or on different browsers. Is there anything I can do to fix this?

Hello.

I have a serious problem with firefox, when I enter netflix and disney+, not only firefox but the whole system crashes automatically (it doesn't show bsod, the screen just freezes) and it only comes back with a hard reset. This can also happen on other websites but much more rarely, while on netflix and disney+ it is guaranteed to happen. The problem started after the upgrade to windows 11 from 10, it has never had such problems on windows 10.

With the edge I normally access netflix or disney+ and watch videos without ever having a problem.

firefox doesn't save a crash report, neither does windows, the mindump folder is empty.

my gpu is a r7 240 and cpu amd ryzen 5 3600.

I am unable to use ecosia although it it noted in settings as my choice. First I get a firefox message asking me to "allow". I then have a message at the bottom of the page indicating that cloudfare.com is creating a link but nothing happens.

Now already can't interact with buttons on pages, open links. I am constantly getting logged out. This problem happens ONLY with FF, not with chrome or other browsers

I got a new computer. Windows 11. I downloaded the Firefox Installer. Clicked open file. Approved download. The window came up for "Optimizing your settings for speed, privacy, & safety. Firefox will be ready in a few moments" with the progress bar. Nothing happens after that. I let it sit for over 4 hours. Any ideas?

Hi, I'm currently unable to log into my e-mail account using Firefox. It keeps says temporarily unavailable and to keep checking back. However, I've been checking back for about half a day now and am unable to log into my e-mail (gmail) account with Firefox. I have been able to log into my e-mail account using another web browser but would really like to be able to continue using Firefox to log into my e-mail account. Thank you.
