Be careful. Something doesn’t look right.

Firefox spotted a potentially serious security issue with ib.postbank.ir. Someone pretending to be the site could try to steal things like credit card info, passwords, or emails.

I want to block pop-up windows and third-party redirects.

When i open settings and then Privacy and Security i do not see an option for this

When i search for this i get this reponse: Sorry! There are no results in Settings for “pop-up third-party redirects”.

My question is a. Does firefox have such a setting? b. If so where have you hidden it?

Pop ups appear when I start firefox saying "Trojan virus detected!" and "system alert!" including "remove virus now" button that if pressed takes me to a site which invites me to download what I assume is malware.

I am receiving popups - sometimes five to seven, stacked, and purporting to be from Firefox or Mozilla but having a clearly "poisonous" URL, The popups warn that my computer is infected with a dangerous virus and want to to click on them to remove it.

I do have an anti-viral program installed - "McAfee".

I went on the Mozilla page regarding reporting bugs but it is a bit above my pay grade to understand.

I am getting these small windows poping up in the lower right side of my screen that state:

Mozilla Firefox

       ATTENTION!
       Click here to remove it!

I am using TotalAV antivirus which is telling me that there is no virus. This only happens when I use Firefox, not Edge or Goggle browsers.

I have McAfee pop-ups that seem to be linked to Firefox. How do I get rid of them? I have used the McAfee MCPR tool, but the pop-ups remain with a Mozilla Firefox notification box. When I open a link from an email I get nine of them. Seconds ago I just got a system update Mozilla Firefox alert box; if I click on it, I get a page to sign up for McAfee.

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?

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?

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!

bold text I am getting a flood of messages about viruses from McAfee and Monzilla Firefox ESR. Not sure if these are real or a scam to click on a link. Need some help in how to stop messages or find out if my laptop is infected with viruses.

When the browser is open - whether with tabs or not - it disables NVIDIA ShadowPlay. The NVIDIA overlay says “a protected app is preventing desktop capture,” and I’d agree with that if it only happened when tabs with DRM content were open, but it happens even in an empty browser.
