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.

Hello!

I first installed Video Download Helper several weeks ago and it worked fine. However, since the update of 04 March, 2026, it no longer works with YouTube. (It does, however, still work with Instagram.) Having checked all of the settings (which I had/have not changed), I uninstalled it today and then re-installed it. This hasn't helped. With YouTube, the Downloader icon (pinned to toolbar) simply remains grey and does not show any videos when opened. I am using the latest, fully updated version of Firefox with Windows 10.

Can anyone help, please?

Many thanks,

Stuart.

I’m currently facing a very frustrating issue with Firefox. I have been using Firefox for many years, and it is my favorite and most comfortable web browser for my day-to-day work. I rely on it heavily as all my bookmarks and other important details are saved there.

However, over the past few weeks, Firefox has been crashing more than 10 times a day. I have already tried all the troubleshooting steps available in the forums and through AI support, but none of them have resolved the issue. I also tried installing and using the Firefox Beta version, but the problem still persists.

In our environment, other users and devices are not experiencing this issue, so it does not appear to be related to internal firewall or antivirus restrictions.

Could you please help me troubleshoot this issue? I am attaching the error screen that appears after the crash along with the crash report for you

The Facebook page on Firefox has the "fly-outs' overlapping the base page instead of the 'fly-out" appearing in a separate tab. When I use Chrome, which I do not want to, the "Fly-out" pops up correctly. I do not want to switch to Chrome ... How can this be fixed? Thank you!

I recently uninstalled and reinstalled Firefox from the Microsoft store and was wondering if my old bookmarks and passwords are saved as backups somewhere and if so where. Or if its deleted when I uninstalled the app.

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.

Hi there,

I'm having a strange issue with a website I use for crypto trading. On Firefox the page layout looks broken and some sections overlap or don't load correctly.

The site is paribu.com https://www.paribu.com . When I open the same page in Chrome everything looks normal and the layout loads properly.

I tried refreshing and disabling a few extensions but the issue still happens in Firefox. Has anyone experienced something similar or knows what might cause this?

Thanks.

I use an online retailer to buy birthday cards and gifts - Moonpig.com. Whenever I choose Paypal as my payment option, it logs me directly into my Paypal account without me entering any details. I have several Paypal accounts and want to choose which one to use. I have no saved payment details on Moonpig's site and having checked, they say that somehow my browser is logging me in automatically. That's Firefox and I want it to stop.

I have no issues with Firefox storing log-in details but I should be able to choose which Paypal account I want to use.

Any thoughts please? UF

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?
