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?

buenas noches, estaba haciendo un analisis y el antivirus me ha detectado un "troyano" en una carpeta de firefox (adjunto captura) y no se que hacer, por si alguien sabe si es un falso positivo o es que de verdad es un troyano

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

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?

Someone has created Mozilla accounts using several of my company's openly available email accounts. I can't figure why. Anyone have an idea why? I know this because all three accounts received the following email message from Mozilla: "Welcome to Mozilla! A few days ago you created a Mozilla account, but never confirmed it. Please confirm your account in the next 15 days or it will be automatically deleted. Don’t miss out on the browser that puts you and your privacy first."

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 already downloaded firefox vpn for windows and already have the firefox vpn extension icon on the upper right corner of my screen.

If I click on that icon extension nothing happens. What can I do ?

I just had another credit card get fraudulent charges. I have no clue how they are getting my card numbers, I have pulled all but 1 from anywhere online, but they just got another one. I couldn't get Mozilla VPN to work it just quit working at all. I turned Pocket off but I'm still getting 17 to 18 instances of Firefox. Dont know where to go now. Thinking of pulling the plug and starting over.
