I don't know whether I can trust three warnings I've recd, ostensibly from Mozilla Firefox: -Attention Click here to secure your data. -McAfee: 3 viruses found, Hard drive is infected! Remove viruses via ...(but I don't have a McAfee account) -McAfee license has expired. Click here to stay protected online? via ....

I have run MalwareBytes (basic free account) and it found nothing.

Maybe settings?

I started getting a different login screen for yahoo and so I was on the lookout for the https:// that would ensure I'm at a real website. I noticed that I don't get any https:// on anything in my FF esr 140. Even if I enter it with the address, it disappears as soon as I click to open the website. I tried out Edge and the https:// is there. Is there some reason this is being removed in FF, as it is something reassuring and doesn't take up much space.

Thank you!

Also McAffee notification with all these popups stating that my McAffee protection expired yesterday - I have never had a McAffee notification for a virus or pair for protection from them. Popups are happening every 10 seconds continuously! looks like about 20 or more popups describing different problems with 20 digit numbers and letters as a serial number of the problem!

I thought Firefox was all about controlling personal info. Seems not. I find nothing in the GUI to turn off the location country flag in the address bar. I have no care to know where any site is located and neither do I wish anyone to know where I am. Can I remove the location country flag feature in the address bar and be sure nobody sees where I am?

In Firefox Desktop 151.0 Beta 1, I'm experiencing a severe DNS leak even with DNS-over-HTTPS (DoH) set to "Max Protection". I've tried all available troubleshooting steps (including resetting `network.trr.*` preferences, disabling extensions, and testing in a clean profile), but the issue persists. > The same configuration works correctly in the previous version (150.x). Has anyone else encountered this regression?

There must be a way to turn off this popup off. This is REALLY annoying when it covers a password box and to remove it i must click outside it and I lose focus on the password box. If you must put he box there then at least leave the first part of the password box clear so I cab click on it and not have to click again to get the focus back.

Is the following true and do you advise taking the steps mentioned. Cookies are dying. Google has been phasing out third-party cookies in Chrome, and Apple has aggressively blocked them in Safari for years. Advertisers needed a replacement that users cannot easily clear, block, or reset. Browser fingerprinting is that replacement: it is invisible, persistent, and rebuilds itself if your setup changes slightly. The result? Targeted ads that follow you across devices and sessions, even when you think you’ve gone "private." And because it operates below the surface of most privacy laws, the protections many people rely on simply don’t apply. What Actually Works to Protect Yourself Most people get privacy wrong by making their setup more unique (rare browsers + 30 extensions = the most identifiable fingerprint on the internet). True anonymity comes from uniformity, not obscurity. Here are the proven defenses, ranked by effectiveness: 1. Choose the right browser (the single biggest decision) Tor Browser – The gold standard. It forces every user to share the exact same fingerprint. Anonymity through uniformity. Brave – Excellent middle ground for everyday use. It randomizes canvas, WebGL, audio, and other fingerprintable surfaces every session. Firefox (with strict settings) – Strong out of the box and highly customizable. Avoid Chrome for privacy-sensitive activity; it offers no native fingerprint resistance. 2. Add the right extensions (Firefox or Brave only) uBlock Origin – Blocks fingerprinting scripts before they can run. (Note: Chrome’s Manifest V3 severely limited the full version; Firefox is required for maximum protection.) CanvasBlocker – Randomizes your canvas output whenever a site tries to read it. 3. Flip one powerful Firefox setting Type about:config in the address bar → search for privacy.resistFingerprinting → set it to true. This standardizes canvas, timezone, fonts, and other outputs so you blend in with everyone else. Takes 30 seconds and makes a measurable difference.

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

Regarding the new built in Firefox VPN. If I have Tabs open and Enable the VPN on a New Tab, does it then affect all previously opened Tabs, only the New Tab, only the New Tab and Tabs opened after that initial New Tab, or ? Also, is there a Meter Display or similar so I know how much of the 50GB VPN allotment has been used or is remaining ? Thank you, very kindly ...-- J V
