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?

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?

This is not the first time you have sent an email to me indicating I should "View all sites where your info is exposed", and each time I receive your emails the sites you suggest are sites I have never seen before, let alone logged into with a password.

I use a Password Organizer Book, with all of my logins and passwords for each site I use. I do not use a password app, and have NEVER used a password app. Each time I go to the website you suggest, It's always a site I have never seen before so it would be impossible to login and change the password. I always check my Password Organizer Book to make sure.

I don't know what you want me to do since I cannot login to the website you are suggesting. Is there action I should be taking? I don't know what it would be, but if you know please let me know.

I don't know what happened I was just doing my normal stuff then all of a sudden I get a virus notifications from Firefox I had did a verification that I'm not a robot after that that's when the virus notifications started can you see if you can do a virus skin for me that will be amazing if you can do that.

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?

To whoever this new CEO is of firefox,

Stop with the AI garbage. Please.

AI is a notorious waste of space in software and all it does is bog down the experience and make everything harder for everyone. Also it is notorious for collecting information and violating users privacy like the lab rats you apparently take us for.

Stop it.

I loved Firefox because I could use it comfortably without all of this stupid AI crap making my life harder. I've already hacked my browser to make sure this doesn't appear but I'm not satisfied. To any other firefox tech reading this get that Anthony guy out of here. We don't want him, and we don't want AI.

Thank you.

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).

Hi there,

I am using Firefox Desktop in Windows 10. I activated master key password for the browser. Suddenly, I noticed that the pop up appear in the browser after open. If I close the pop-up or cancel it then it doesn't force me to type password. I easily can use the browser without using password. This is horrible!

please fix it

I have a website that keeps opening every second, opening multiple tabs and will knock me out of what I am doing. How can I I block this website? I am not interested in it and have never signed up for information from it.

I could not access this website https://sevasindhuservices.karnataka.gov.in/home.do why please help me

I seem to have found a fake Firefox phishing website. The content of the website is in Chinese and it is included in Google search.

The fake websites are cn-firefox.com and www.firefsioix.com, I hope the community members can confirm the website information.

I have no interest in it and view it as a security risk and liability. I've been using Firefox for over a decade, every since I realized how horrible Google is. Why the heck would Mozilla do this?

I purchased mozilla vpn. It worked fine for months until a few days ago. Now I can't use the internet at all without turning it off. With the purchased version off I turned on the vpn in the firefox browser. This seems to work fine but it is only in used within the browser. The ;purchased browser is installed on my Iphone and my Mac laptop. Same problem with both. I also received an email a day or so after the trouble started saying my password for Mozilla had been changed. I did not aske for this change. Since my internet access was shut off I couldn't initiate a change of my own. It took me another day to figure out my problem was the browser. At that point I changed my Mozilla login password. I wpou;ld ;like top keep usiong the purchased version of the mozilla vpn on both my laptop and my iphone (13) because it looks more thoroughly at data going in and out of my devices.

Thanks for your help Steve Krebs
