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

I assume Mozilla developers are working on this?

Quote from the article

"Its capabilities are a step change from the previous best models. Given the challenge of attacking the Firefox web browser’s JavaScript engine, Anthropic’s previous most powerful model Opus 4.6 succeeded just twice, compared to 181 times for Mythos. Most worryingly, the team found that engineers with no security background could use it to develop successful attacks overnight."

Scam Nowadays became regular .before foxfire browsers was top est saver legends, what happen nowadays not understandable very weak security privacy Is there some one discripe Us what what type of technical problem exsit!!!

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.

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.

Some users are abandoning Firefox because of the difficulty of protecting against Firefox fingerprinting. Therefore, I strongly recommend adding an option in the settings that allows the digital fingerprints to be made random, or at least, if it is difficult, to make the fingerprints indistinguishable. This will help improve Firefox’s reputation and the privacy of its users. Love you all 3:

Device Bound Session Credentials

Google has made Device Bound Session Credentials (DBSC) generally available to all Windows users of its Chrome web browser.

What is FIREFOX doing to defend us from session cookie stealing malware (STORM)?

i am having pop-up messages that there are viruses on my computer causing security & privacy issues, your timely help required as my work using my computer is lingering on.

I just purchase Malwarebytes Standard plan to help strengthen the security of my laptop which runs on Windows 11 .After installing the standard plan, Malwarebytes recommended I install, for free, an add-on called Browser Guard for Firefox. However, Mozilla sent a cautionary statement: 'This add-on is not actively monitored for security by Mozilla. Make sure you trust it before installing.

Is the Malwarebytes Browser Guard for Firefox safe?

Seriously Mozilla.

First with ramming AI everywhere in Firefox, now a browser VPN, why?

I do not want a VPN the web browser that I didn't ask for or other features you think people need without asking.

Corporate and business users would not have a bar of this either.

Enough!

Remove this from Firefox please in the next release.

In the meantime, tell users how to disable this VPN via the Settings and "about:config" so this never gets turned on.

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.

Is there any documented way our I.T department can disable the ability to connect to or even see the Firefox VPN that is being rolled out via group policy or another settings method? Firefox is a great asset for our agency but we cannot have users having the ability to bypass our web filtering. If there's not an option currently, could we have the IP's or the servers that it runs off of so we can manually block it in our firewall?

I'm sending this from my phone. My desktop FF (Win 10) suddenly displayed a black wireless globe type icon called Prox-Media pinned to my taskbar. I can't find the app on my system, though, but the full path leads it to a firefox.exe file. Before my brain kicked in, I'd clicked on the icon right after noticing it, and Firefox came up with the attached error message displayed.

"Prox-Media" comes up nowhere in my searches - not as legit, not as a virus - just no results. Can you help?

I have a paid AVG account and I ran a deep scan but it found nothing.
