Normally Ctrl+Shift+T reopens the last tab I closed in that specific window, but after the most recent update it reopens the last tab I closed in /any/ window. Is this happening to anyone else?

I have suddenly lost all my firefox data today.. after creating a new browser profile? I never bothered creating profiles and stuff when the update for that came and it seemed like Mozilla never forced me to create named profiles until today when I open it again after booting up and it suddenly asks me to make a profile for the browser and after I did I just saw that I lost everything, I have a firefox account that's sync to my mobile phone but I can't seem to sync it neither, my browsing history, bookmarks, and passwords are all gone and I've even checked the AppData/Roaming/Mozilla/Firefox folder for it and even the recycle bin but I can't seem to find a single trace of my data before firefox forced me to create a browsing profile for my computer. Hoping someone has a solution to this.

My system was hacked and I had to factory restore it. I didn't write down my login/passwords because I was informed that as long as I had my sign in for FireFox I could restore them on my system.

Alas, I cannot figure out how to do this. I do not have a passkey, a profile or anything other than the email address for my system.

Can you help me? I put all of my important documents in Dropbox and now I can;t access that either.

Anything you can do is appreciated.

My bookmarks toolbar shows but it is blank. I had 60+ bookmarks on it. Why did Firefox trash my bookmarks?

Why did Firefox force me to create a new profile? I can get to my old profile, but the bookmarks toolbar is blank. The bookmarks showed for a while, then the toolbar went blank. What gives?

I have had all kinds of problems with Firefox the past several years, and I am about ready to can Firefox and go with Edge and Chrome. In my opinion, Firefox is a piece of crap, and I am fed up with it. I already have Edge and Chrome, but mostly use them as a backup when Firefox doesn't work right.

Is there any hope Firefox will get better, or should I jump ship with the other rats fleeing this despicable piece of junk? I have been hanging onto Firefox, because I am familiar with it and used to like it, and have used it for over a decade. But my patience is growing thinner.

WebRTC DataChannel worked perfectly in Firefox 147 and earlier, but after upgrading to Firefox 148, send() throws InvalidStateError immediately after onopen fires. Same code works in Chrome and previous Firefox versions.

const dataChannel = pc.createDataChannel('kvsDataChannel', {

   ordered: true,
   maxPacketLifeTime: 3000

});

dataChannel.onopen = () => {

   console.log('open, state:', dataChannel.readyState); // Shows "open"
   try {
       dataChannel.send('hello'); // Throws InvalidStateError
   } catch (e) {
       console.error('Failed:', e.name, e.message);
   }

};

Error: InvalidStateError: An attempt was made to use an object that is not, or is no longer, usable

Environment: Firefox 148.0: Fails OS: Windows 11 Firefox 147 and earlier: Works

Question: What changed in Firefox 148 that broke DataChannel send()? Any workaround while this gets fixed?

I have an Intel I5 PC that runs MS Win XP. The reason that I'm still running that ancient OS is because of whats inside it. I have two old boards in it that I still use and quit honestly can't afford several thousand dollars to replace them. And the new machine to go with them.

I need to get online to download the few pieces of software I need That are still out there. But like most sites they examine your machine to see what versions you need and it's a download and install package. So I can't use a different PC.

My question is: Is there a version of Firefox I can download that will work on XP, and not be ignored like is done to IE 8. And that I can then transfer to the XP (service pack 3) box for installation?

Everything is gone, I have had to reinstall windows 4 times in the last week with a new PC and now all my sync data is gone...Chrome remembers everything fine and Mozilla did remember everything until this install and now its not syncing anything.

If this stuff is gone so am I.

Have tried logging in with my google account, tried logging in with Moz account, tried sync button over and over tried restarting, tried uninstalling and reinstalling and manually deleting all the folders STILL NO SYNC DATA AT ALL.......

Firefox installed a new release and now all my bookmarks, add-ins etc are gone. I went to About:profiles, but I when I launch the other profile that is there it still show the new profile

Ok, This latest version of Firefox is really Bad. It hangs on a lot of my online login accounts. Important things like my Amazon Chase Banking App. My Subscription access to HeyGen logs in for example but it won't work with features like creating your avatar. There is a LOT wrong with the current build.

Firefox keeps forgetting my bookmarks, so I uninstalled and reinstalled Firefox. After reinstalling, Firefox defaulted to my wife's profile. I then tried to recover an old backed up profile using sync. I selected the right profile, but Firefox reports there are no compatible files in any of several backup file folders.

I just reinstalled my OS (Windows 11), and installed Firefox, logged in, and just couldn't believe my eyes. Everything is just gone. Passwords, history, everything. Why then Firefox Sync is using email and password if it doesn't have any cloud storage for passwords and doesn't even work like chrome? Should I install Firefox on my iPhone to regularly sync two devices (manually), to store passwords on another device, then sync back?
