I just got this email: Did you sign in to Firefox? Help us keep your account safe by approving your sign-in on: Firefox on Windows 10"

This is after setting FF as default again (3rd time today). Got into this problem trying to report that FF behaves differently when using W11 HOME vs PRO. Don't know when this started. This system has been a "home" system from day 1. When I go check defaults with W11, (only O/S on this laptop) it shows that FF is the default browser for many things.

But if I do an update, or have to do a reboot, first time started, it wants to be made the default *again*.

NOTE: Mozilla sent the above email to me that this is FF on Windows 10. This is W11 HOME, not 10.

Thank you for your attention to this matter.

I believe I was hacked into. One minute I'm signed in the next minute after I leave a site I am being asked to sign back in again and again. This time someone is changing my sign in credentials.why??

This appeared on my passwords setting page on FF

After a little googling I thought the page was probably safe but in fact it's ServerNotFound

What's going on? Has FF itself been hacked?

I prefer to have VPN support no matter how I am using the internet. I would prefer that Mozilla get rid of all of the debug statements in the existing paid for VPN as it is a drag on my system. The debug issue exists on Windows 11, Android 16 and Linux (Debian 13.4).

Hello,

why you advertise a A free VPN you can trust, now built into Firefox ! when it s not free at all ?

Firefox was updated. I was Hacked. Now I cannot log into my email Provider. Firefox is my default browser. How do I access my email provider via firefox browser now?

Today (February 25, 2026) I received an email notice, apparently from Mozilla Monitor, advising me that my "Email addresses, Partial credit card data, Passwords, and Phone numbers" had been exposed in a data breach at Canadian Tire. This email seemed legitimate (the sender was breach-alerts@mozilla.com), but since it gave me a link to login to Mozilla Monitor, my first concern was that this might be a phishing email and it would be dangerous to click on that link. Instead, I went through the Firefox settings to login to my Firefox account and from there, I checked what Monitor had reported. The Canadian Tire breach was not listed there. However, when I went to haveibeenpwned.com, the Canadian Tire breach was listed there. It showed that the breach occurred on October 25, 2025. So why was the breach not listed for me on Mozilla Monitor? And why would I have received an alert from Monitor 4 months after the breach? Was this breach alert notice actually a phishing scam perpetrated by someone using the information from haveibeenpwned.com as bait?
