For years I have had a second monitor with Twitch or YouTube active while gaming. Now, for the past week, whenever I am tabbed into any game my video will freeze. Audio is unaffected. I have tried network.http.throttle.version to true or false, and network.http.throttle.enable to false. Hardware accel is off. Either setting seems to have no effect. What else can I try to fix this issue?

Firefox does not work with many websites any more. I constantly get notifications from websites telling me I need to update my browser. I am not able to download many forms and some videos no longer work. I've tried to update but I'm on some ESR & still get notifications that my browser is not supported by many websites. I have windows 11 (chg from 10 in March 2025), 64 bit but it says my system is not sufficient & that I'm running windows 8 which I am not. I have made the decision, after over 10 yrs using Firefox, that I'm going to move everything to Chrome. I HATE that I have to do this but I can't get any support/help from Mozilla or firefox to correct whatever the problem is. If anyone has any suggestions, I would appreciate. Done

I imported about 80 bookmark folders and subfolders from Chrome. These are the only folders I use, and I access them by the Favorites button at the left end of the bookmarks toolbar. But when I type CTRL + D, the menu shows only Other Bookmarks. I click the right-hand arrow, which adds Bookmarks Toolbar and Bookmarks Menu. How can I save to my imported folders?

Hi there, I sound like a silly question but I'm really lost what is supported and not supported in regards to passkeys.

I have learned that Firefox supports logging in with passkey, but where are the passkeys stored? Does Firefox store them internally (like passwords) or do I still need a third party service?

I use Firefox on Android, Windows and Linux, so I would like to synchronize my passkeys between all devices, operating systems.

Thank you. Stefan

Dear Firefox Support Team,

Hello, I’m writing to ask for help regarding a serious issue I encountered while trying to install the international version of Firefox.

Since the Chinese edition of Firefox is shutting down soon, I backed up all my data and uninstalled the previous version tonight. I then tried to install the international version of Firefox. However, during the installation process, I ran into a major issue — the installation was extremely slow, and even after waiting for over an hour, it still did not complete.

I’m not sure what’s causing this problem, and I’d really appreciate any support or suggestions you can offer. I truly enjoy using Firefox and value the experience it provides. I sincerely hope I can continue using it without interruptions.

Could you please advise me on what I can do to fix this and successfully install the new version?

Looking forward to your kind assistance.

Best regards, Lily

Since the last Firefox update, my computer's speed has become terrible, every attempt at opening/closing tabs takes absolutely ages. Eventually today I opened Task Manager to see the Firefox is hogging memory hugely, and even got a message suggesting I close Firefox because it was causing my computer to operate slowly. I eventually managed to close it, switched to MS Edge, and everything went back to normal. Anyone have any idea what is happening here?!

I was trying to setup 2FA on my Mozilla account on Firefox pc browser (140 version). The process completes without issues with Aegis authenticator app, I download the backup codes and I even get the email confirming the recovery phone number was added. On the Mozilla accounts page 2FA turns to enabled. (I'm on Windows11 with latest Firefox browser version)

However after a simple refresh, it turns back to disabled. I repeated the process and same thing happens. Same even on Firefox Android. What could be the issue here?

Hi, I have a laptop and connected additional monitor. FF works normally until I move the floating video window to another monitor. Then it 'rescales' itself, the floating video changes ratio and can't be in full screen. When I move back to FF and want to make a normal full video (YouTube) I don't see anything because I can see using alt+tab that FF minizes itself to the most smaller window. The full screen youtube video also is just a fraction of the full screen - I can see the scroll bars but there is no way to extend it to full monitor. To reset it I have to switch off FF or alt+tab, then windows+arrow to make other program to occupy for example half the screen and chose FF to feel the rest and then extend and full screen again.

It's only happening with connected monitor that extends my monitor.

Instead of syncing my current settings, sync just overwrote them with an old, outdated copy from another device, completely ruining my addons, bookmarks and various other settings. I managed to restore the bookmarks, but is there really no proper way to undo this or prevent such thing from happening in the first place? Is there no way to control if I want to sync my setting TO the server or FROM the server? How such a vital decision is even made then and why wouldn't there be a way for a user to control that? This is so disappointing :(

Hi, i am trying to upload a Firefox extension, it is my first one and i am trying to upload it. I however cannot get it to work as the code my authentication app does not work. I have tried several authentication apps but i am always returned with the same error message whenever i enter in my code. "Invalid two-step authentication code". Is their a fix to this, so far i tried using google authenticator and DuoMoblile. Thanks

Since updating to Firefox 141.0 (Win11), I've had issues with performance and on-screen behaviour of dynamic web pages/sites. The problems do not manifest on Chrome, or on a reinstalled version of Fx 140.0.4 on the same computer running at the same time (and with copy of original profile's data files, extensions etc.), they do manifest on a new Firefox 141.0 profile with only one tab open.

The problem happens on dynamic pages (e.g. gmail.com, boardgamearena.com/lobby) but doesn't seem to happen on static pages. Note that this doesn't depend on page elements moving around the visible window (e.g. panels opening and closing).

The manifesting problems:

• Screen pointer rapidly switching between standard arrow pointer, mouse with index finger (clickable link) and serifed-style insertion bar, even when positioned on a part of the page that is not a link or a text box. Video (MP4, <1MB) showing behaviour at https://imgur.com/a/absjTh4.
• Browser intermittently fails to respond to browser actions (mouse clicks, keyboard entry)
• Small increase in browser CPU usage

Problem is worse if general CPU usage (from other applications) is already high - low CPU usage reduces but doesn't eliminate the problem. (Established by changing my BOINC settings and/or snoozing BOINC and observing; I have a gadget that monitors CPU and other resource usage.)

The fact that I can see the problem occurring on Fx 141 but have Fx 140.0.4 working fine at the same time on the same page, suggests that this is a Fx 141 issue. Regular malware scanner and an alternate found no issues.

Happy to do more diagnostic testing if it's helpful.

Hi!

My problem is that I had a synced account, and I had to redownload windows11 to my computer. Naturally, I was logged out. When I logged back in, I had forgotten my password so I made a new one, and once I got in to my account everything was missing. The only password it had was the mozilla one I had just reset and saved. I still have some files in my file explorer but none of them seem to do anything.

What should I do? Is there any way of getting my bookmarks and passwords back?

Thank you.
