For the last two years the issues with video stutter have been worse and worse for me. I don't know if it is because of a different codec the video is using, but if it was I would expect the fans to ramp up from trying to decode it. Instead, my laptop stays always silent, but the video laggs like crazy when I want to play it at native 1440p.

I cannot view or change the video codec, since the current issue happens on a platform (herohero.com) other than youtube.

I recently bought an new HP Win 11 PC to replace my current Win 10 machine. Running latest FF 144.0.2 on both. How do I transfer my complete FF profile (bookmarks, bookmark bar, login data, EVERYTHING) to the new PC? Want the new install to be an exact functional copy.

THANKS!

When I want to login with my Firefox account it asks me for a code as 2 factor but I can't remember that I ever signed up for 2 -factor . I have 2 apps fro 2 factor: google and Microsoft but neither has Mozilla identification in it. I would like to sign up for 2 factor but it looks like someone already did that for me. What now?

My question is above!

I had a free chatGPT on firefox sidebar. you changed it to Anthropic Claude without my permission. Now I have to pay for something I was getting free as a student of a university.

How can I restore the FREE ITEM AND GET RID OF SOMETHING I WILL HAVE TO PAY FOR...AND STILL USE ai?

Hello all!

I've started having an issue in the last few days, with apparently two separate Firefox installs. A few days ago I was greeted by a fresh, blank install of Firefox and had to set everything up and sign in as I usually would on a fresh system install. Today, however, I somehow managed to launch both of them at once (I don't know how, as I just use the UI shortcut). After closing both fully, I can now only start the "old" one via the shortcut.

OS: Bluefin / Fedora 42.20, Gnome 48.6

According to the list of flatpaks, only one is installed. Unfortunately that's roughly where my knowledge of Linux ends, so I can't troubleshoot this further. Help will be apprecciated, as I don't want to roll a die on which of these will start up every time I reboot.

A folder appeared on my desktop titled "Old Firefox Data". It is dated 11/2/25 at 12:47 PM. What is this and why did it just appear on my desktop? Do I need to keep it or can it be deleted?

When I opened my computer this morning, it said Firefox crashed. Yesterday, I was scammed by a scammer claiming to be from Microsoft who had me do many things on my computer to remove a virus that wasn't there. Instead, I suspect he may have access to my information now. So this morning after it said that Firefox had crashed, I asked to open a new Firefox session and things seemed to be normal. Please double check to make sure there is nothing wrong with my Firefox account and let me know. Thank You!

After having upgraded my W11 system to 25H2, I cannot install any extension. Installation terminates with "... something may be broken". I'm using FF 144.0,2. FF is used in more than one account alternatively.

On a second system, with less security measures, I have no problems.

I am using the new profile switching feature in the UI, from top of the hamburger menu. Firefox is my default browser on Windows.

Now, I want all links I activate from other Windows programs to open in a specific profile. I use the other profiles for auxilary tasks.

Is there any way to achieve this?

2 days ago you tube is suddenly blocked. 11/6/2025 i would click a video, it would "blink" at me and do nothing. i updated firefox, ublock was updated about a month ago and now i can't even get a home page to load. i have refreshed and restarted

Firefox used to save unknown files according to the save files setting. i.e. ask where to save files. Now if opens unknown files as text in a new tab.

How can the correct behavior be restored?

Alternately, can the Linux snap be fixed to allow saving of new file types? {The procedure shown in https://support.mozilla.org/en-US/kb/change-firefox-behavior-when-open-file is not present in the firefox 141 snap.

I generally always use Firefox on my PC for everything.

I also often chat with Amazon as they are never short when it comes to fucking my orders

I have not used Amazon for the past 2-3 months and when I finally placed a new order 3 days ago, to resolve the usual non delivery issue, I contacted them via Live Chat, however instead of seeing Chat window pop open as usual, all I got was ABOUT:BLANK in new tab, hmmm...

So far to fix this or at least ascertain cause:

- I contacted Amazon.fr (where I live) and guy at digital services said, "nah, no flies on us, it's Mozilla's fault" - Edge, on same PC (windows 10), works OK for chat - Launching in safe mode changes nothing - Nor does disabling NordVPN - I also added Amazon.fr as "exception" in pop-ups, to no avail - and when I unchecked block box to enable all pop-ups, no better luck - lastly, on my iphone via Safari, all is good, assuming one enjoys typing with 1-2 fingers

my version of Firefox is up to date: 144.0.2

voilà

suggestions?

thanks
