Firefox Community Forum

There’s no information on how to sign out of the AI bot itself. For example, if you use Copilot and sign in, then realize you used the wrong Copilot account, there’s no clear way to sign out and log in with a different account.

Ever since the last update or so (I'm currently on 145.0.2), simply opening a YouTube tab is enough to bring my browser to halt. Looking at the activity monitor on my Mac shows "FirefoxCP Isolated Web Content" using an insane amount of resources, multiple instances of 101% load on my late 2023 MacBook Pro (M3 chip).

Any ideas?

Dear Mozilla,

First of all I love the browser. 2nd I am trying to enable this setting "Secure Firefox passwords with device sign-in" for my Mac Os fleet.

I need to do this with the hepl of a phlist which i will upload on our MDM and that will be pushed to the Firefox browser.

I am writing to you because after many tries I could not find out wich settings on about:config directly implies this one. So i would kindly ask for some direction.

Thanks and best. Endrin

When I play a downloaded video that is in English, my downloaded file plays back in a foreign language, not English. What am I doing to cause this and how can I have the English version only in playback everytime? Thank you so much, being a pensioner I am eager awaiting the ability to donate to you excellent work as often as I like.

I have a new computer and I want to sync my Firefox account but the Sign In button next to Sync and save data options are missing from the browsers in both devices.

How do I fix this issue?

For the last two days, I have been ubable to access settings (X,). When I click the settings cog in th toolbar, thr toolbar grays out. I have also tried to access settings using the Hamburger Menu, clicking on settings, with the same result. I have clicked on Firefox in the menu tab, same result.

I have closed and restarted Firefox, with the same result.

Additionally, I can only close Firefox by force quitting. I don't know if the two are connected.

TIA. Keith

I'm trying to use an old Apple Powerbook as my 2015 MacBook Pro just died. I use Firefox as my browser on my PowerBook, and it is asking me to enter my old phone number and is not accepting my new phone number.

We have two computers in our house -- one connection. From my computer I sent something to my daughter, the second computer in our house. For some reason, my whole Facebook account transferred to her computer ad she is unable to use her own Facebook account. We have no idea how this happened. Can anyone help? Thank you . .

I have 4 macbooks and iphone w. about 10000-19000 bookmarks. Last n. I noticed what I bookmarked on 1 machine wouldn't show on another. A pop up said "your profile has reached a limit. A device can have ony one identity..make another (sic)...." I did that, and found the bookmarks from "classic" profile, WHICH I'VE HAD ABOUT 20 YEARS, weren't imported. I uninstalled, reinstalled Firefox, managed to get the bookmarks back via a desktop folder I'd made, thank god! It didn't restore the 50 passwords, and still won't accept the previous password..which is another can of worms-it actually won't let me change my p/w w.o "you may lose your personal bookkmarks passwords etc!:" Even the 32 digit code (which I had saved) is not working...and it doesn't let you get another one unless you have a p/w!!!! Is this sounding a vicious circle....I am going to not use sync or another profile, b'c I'd rather keep my personal data (bookmarks) and rightnow, I was able to 'restore' to the original profile!!
