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.

I have been using Firefox for 20 years. My company Ameriprise Financial has uninstalled it and when I try to reinstall, they immediately uninstall it. They tell me there are security vulnerabilities with Firefox. WTH Firefox?

They want me to us Google Chrome now instead.

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?

There is a program called TENS (Attached image) that is used by the Dept. of War that was developed by USAF. I would love to have a Firefox version that does the same thing on a bootable flash drive. I would use this only for banking, medical, IRS, SSA, etc. I am sure others would like it for different reasons, so include a statement to users that IP only log file is generated and state that this is for security/quality control/legal accountability of Firefox purposes and that this data is saved on your server.

The goal is to avoid Google. Copilot advise me to under Security, to uncheck the box "Block dangerous and deceptive content". Is that advisable - should I comply?

Further to the malware, it references Windows OS but has seized her Mac. I powered off. Rebooted. Within about 15 seconds of opening Firefox the malware pops up and freezes the Mac. By the third time I was able "force quit" Firefox and the other applications function properly. I beleive I deleted Firefox but probably didn't get it all out. I reinstalled firefox and upon booting up Firefox the malware is still activated. Can you please assist with a fix?

seems that after Firefox 150.0.3 (20260511200624). I cant access locally deployed servers that are not secure. the Firefox forces https when hitting http://localhost. I've tried to disable the HTTPS setting altogether. Even in developer mode it still overwrites http to https.

I am using the Firefox browser. Lately it has been redirecting me to a malicious website: mercu-wgp.com/zclkvisitor. What can I do to prevent this? I have FF 150.0.3 64 bit on a W'11 computer.
