Lately, I have been noticing that new Firefox browser windows (not a new tab, a new window) have been opening seemingly randomly on me. The sites in these new browser windows are always commercial in nature and seemingly random in subject matter. I am not aware of having clicked on anything that would cause the new browser windows to open. I need to know how to block this from happening; I am unable to figure it out in the various Firefox Settings.

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.

I am getting pop up after pop up using Firefox even though the pop up blocker is on. I am afraid that I need to use a different browser even though I have used Firefox for lots of years. I was especially annoyed that on more than one occasion a pop up happened when I was trying to get on my bank website. The pop up stated that access to my bank account had been blocked and I needed to call a phone number to have it unblocked.

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?

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.

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?

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."

Since several days every time I visit a webpage I see that there is a popunder from syscsrv.com!

What can I do to stop this?

Hello,

I am running windows 10, firefox 148.0.2 (64-bit) and when signing onto amazon.com I am greeted by this annoying pop up. Screenshot attached,

"Windows Security Making sure it's you

Please sing in to amazon.com This request comes from Firefox, published by Mozilla Corporation"

I do not find a need for this pop up and would like to know how to disable it. If you know how, please let me know!

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?

This happens occasionally for many months. It is still happening on v147.0.1. I start the computer, open Firefox, and the browser loads previously viewed pages, including my Gmail account. The Gmail page has me already logged in, and I DID NOT provide my password! This has to be a big security risk. If some one were to use my computer, or it was stolen, they would have complete access to my Gmail and all Google properties!
