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?

I just set up a Rakuten account which alllows me to buy things on line. Mozilla-Firefox won't let me buy through this website (i.e., the Rakuten website). How do I get Firefox to allow me to do what I want. I have no idea which version of Firefox I'm using. I'm assuming that its fairly recent.

When using Eff fingerprint test https://coveryourtracks.eff.org/ it shows a nearly unique fingerprint for FF for version 133. How can this be corrected to show randomized fingerprint ?

Firefox detected a potential security threat and did not continue to divar.ir because this website requires a secure connection.

An infected website warning by AVG comes up every time I open Mozilla. It doesn't occur with other browsers. How can I get rid of it. It seems like it's the same URL.

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.

For a long time, while the Number Lock light is "on" on my keyboard, Firefox does not recognize that it's on. This should be a basic binary. 0=0, 1=1. 1 should never equal 0.

I have to got into another program and type numbers there to get it to work. But it doesn't last. I hate it when I'm trying to do something quick and I have to fight with something that I should NEVER have to fight with.

How to I get Firefox to ALWAYS recognize that Number Lock is on when it is on?

Hi! This just started today. Not a problem before but...there is some ad blocker that won't let me watch you tub videos on my computer. I've tried fumbling around in settings, privacy, ad blockers etc but not finding the magic button. Any suggesions I'm on a windows 11 pc, using firefox and Gmail suite apps

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.

This is my second request for help. I want to thank those who tried to help me before, but nothing has changed. When I open Firefox I immediately receive three messages, approximately 4 inches wide and 3 inches long on the right side of my browser, covering the areas I need to get to. They claim to be from Mozilla Firefox, have the Firefox logo on the top left, warning that I have a virus, or my files are infected, or a large Alert! And that I need to click "here" to fix the problem. It shows a strange "address" a string of random letters and the odd number and the words "merge network protocol." I did not click on this, or the "dismiss" that is shown. I did, however, click the X in the top right corner of one of these. It disappeared for about three seconds and was immediately replaced by another warning of some type. These messages do not go away when I leave Firefox, they follow me wherever I go. Restarting the computer gets rid of them, but I can't access Firefox without them returning. I have tried to alert Mozilla about this, but have not heard back. Any suggestions?

Good morning,

Today I have formatted my computer. So, next step is install all the software I use. I use your app and when I reinstalled, I received your advice to update mozilla. I have download the file and I usually check with virus total the link and the file. Your link is ok but the file have a malware.

I'm sorry but how I can trust in your downloads and advices?

Thanks

A couple months ago I started getting pop-ups from Firefox notifying me of e-mail messages in my AOL tab.

The pop-ups appear randomly, and do not cover all e-mail messages, only what appears to be random ones.

The pop-up appears in a generally black box. Firefox in the upper left corner, and then some variant of an e-mail message from my in-box.

The message (pop-up) even appears in the log-in window, when I have locked the computer and have yet to re-sign-in.

I believe I have my Firefox pop-up parameters correctly set.

So AOL or something in Windows-10??

Just a little annoyance................
