I'm suddenly getting repeated/multiple Mozilla Firefox "Browser Alerts", "System Warnings," and "McAfee Critical Virus Alerts" that are wrong and dysfunctional. They pop up every few seconds. They contain "Remove virus now" and "quick scan" buttons, but these only take me to a bright red screen that says:

"Deceptive site ahead Firefox blocked this page because it may trick you into doing something dangerous like installing software or revealing personal information like passwords or credit cards."

These come even though I haven't tried to access any "deceptive sites." I have to x all of them out to clear my screen.

There's obviously a defect in your warning system. How do I stop this?

How do I stop pup ups with several different warnings. At the top of ALL popups say Mozilla Firefox . I clicked DISMISS, then another one will pop up. 1.) Red shield with the word Warning! Click here to secure device! anti virus notification. 2.) Red and black shield say Virus found. 3.) Blue Windows symbol with a the yellow triangle and !, Click here to remove it 4.) red setting wheel, Trojan virus detected, Scan and delete your system.

Please help

How can I suppress a recurring pop-up in Firefox that claims my computer is infected with a virus and it instructs me to download McAfee Antivirus to clear it out. I've done multiple scans with my Norton Antivirus which showed I had no viruses. The fake pop-ups appear to be coming from Firefox.

This past Friday morning, May 29, I tried to access www.healingwell.com which I have always been able to do. But this time Firefox gave me a red screen with message: "Firefox blocked this page because it might try to trick you into installing programs that harm your browsing experience, for example, by changing your homepage or showing extra ads on sites you visit." And same message again over the weekend. But yesterday, Monday June 1, I was able to access that website, and all seemed normal. Why did Firefox give me that message on Friday, but not yesterday or today?

Hello,

I downloaded the Firefox installer from the official website (https://www.mozilla.org/ru/firefox/download/thanks/). After downloading, I checked the SHA256 hash of the file: 051deb55cf9579e1f9b3bad71ec4a390353c568ef21849671953d08343b4e890.

However, this hash does not match any of the hashes listed on the official page: https://ftp.mozilla.org/pub/firefox/releases/133.0.3/SHA256SUMS.

Additionally, a VirusTotal scan flagged the file with a potential virus alert.

Could you clarify why there might be a discrepancy in the hash and whether this file could be legitimate?

Thank you.

Why is Firefox leanining into this ai nonsense? Its antithetical to privacy amd security, it slows down the browser for no benefit, so i end up jumping through hoops to turn it all off. If I wanted AI, I'd be using chrome or edge. I don't want AI. If firrfox continues to shove this ai onto us i'll have to switch again. Its self sabotage at this point

I am using version 143 for Linux and it is suppose to have improved fingerprinting protection. But when I go to https://coveryourtracks.eff.org i still see a result that says "your browser has a unique fingerprint"

Is there a parameter I should be enabling ?

When I logged on to my laptop this morning, it appeared that my Firefox was updated. I immediately was inundated with pop up alerts from McAfee. I checked it and learned it was a scam. However, my husband thought it was legit and allowed them to do a scan!!!! He didn’t download any software. What do we need to do?

(I did see the solution to stop these pop ups and have already resolved that issue. I’m just worried that some party scanned my laptop.

I did not ask for to have intrusive AI slop put in our browsers.

I literally switched over to Firefox for very specific reasons. I stopped using other browsers, such as chrome and other chromium based browsers, because they eventually got filled with AI bloatware slop that didn't really add anything to how we use the internet browsers

Firefox literally had something going on that stood out from rest of the market, and now you're willing enough to throw it all away for short-term gains to be made off the AI bubble? Firefox could've been the market leader in having a simple browser with no AI slop or general bloat added.

Not to mention the fact that AI is just straight up invasive as its basically just thinly veiled attempt to get more sensitive data harvested off users, to produce more money without paying compensation for the time used on the browser. In addition to opening up vectors for identity theft and fraud.

Once again, why is it absolutely necessary to have AI in the browser?

Was reviewing my Settings. Looked under Privacy & Security, Browser Privacy, Certificates, View Certificates. The Certificate Manager has many listed under “Authorities.” Some look suspicious. How do I determine which are valid and which should be deleted?

Windows Defender is blocking Yandex.Ru, which is not even been tried to be access from. It showed in the Event Viewer that firefox.exe tried to reach Yandex.ru. Why is Firefox trying to reach there? There are no extensions apart from Firefox Multi-Account Containers installed.

Please advice.

I think that i get some virus in my computer, in the last two days some of my accounts were accessed by an unusual way.

I´d like to know if the problem was my passwords kept on firefox, all the apps that were hacked had the password saved on the firefox manager.

There's a way to know if my passwords on the Firefox were stolen ?
