You know how you can block pop-ups and third-party redirects on firefox desktop, then make a list of exceptions? Is there a way to do this on firefox for android as well? This screen keeps popping up and its driving me mad lol.

Settings HTTPS-Only Mode: Enable in all tabs DNS Over HTTPS: Default Protection Enhanced Tracking Protection: Standard Firefox Version: 149.0.2 Device: Samsung SM-A556E OS: Android 16

Extensions: Adguard Adblocker, Decentraleyes, and uBlock Origin

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.

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

Hi, I'm working with a website sponsored by the American College of Surgeons. Some of the parts of that website are blocked by Mozilla. Is there a way to trust that website completely?

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?

I have 2 browsers on my computer, Firefox and Edge. Only on Firefox I have gosearch , I have tried many ways to remove this malware from Firefox, do you have any ideas how to remove from my computer? Win 11 64 bit

ie every time I closed it it would reopen- 14 times when I am trying to read my emails yesterday and 6 today. but I thought it was my internet security causing the problem. I kept getting notification that a certain site was attempting to use my system,. The worst thing was it kept flashing on my screen and wouldn't go away, There was no clue who öwned it, my security or Mozilla's. It was finally resolved by contacting my computer guy, but we never identified the source. the site that was being blocked started with pssst.........com, or something similar but it was driving me mad trying to get it off the screen. If this happens again, how do I get rid or stop the continual notifications? Of course I have nothing to show you as I have since deleted it, sorry. as I was just relieved to see it gone.

Thank you Angela Johnson

Relevant to Firefox running on Ubuntu 22.04 Linux and an x86_64 platform.

Until roughly 2/2026, it was possible to load a security device by opening Settings, Privacy and Security, Security Devices, then browsing to a shared pkcs11 shared library, in my case /usr/lib/x86_64-linux-gnu/opensc-pkcs11.so, and clicking Load. The shared library would load and would be loaded subsequently whenever Firefox was started. For roughly the last two months, Firefox would pop up an error saying it was not possible to load the security device, but it would actually be loaded and it;s functionality would be available for the current session. For the last two weeks, the library would load without error, but only for the current session. Starting on 4/13/2026, some functions in opensc-pkcs11.so work, but not others. For example, it is no longer possible to connect to MS Teams web interface.

Recently getting a warning of virus. https://aiwebfreeinstalls.autos/1igfp2gfa/l?btd=dHJrLmNvbG9ueS1zY29yZS1yZWxhdGVkLWRvbmtleS5ydW4&exptoken=MTczNTY5NjQ2MDA1MA%3D%3D&lang=en&lid=bf3dcebb-0892-4a88-9a74-4f2979083dc1<d=dHJrLmxlYWQtd2hpbGUtc3ltYm9sLWF0LnJ1bg&pd2q=YTE9YmYzZGNlYmItMDg5Mi00YTg4LTlhNzQtNGYyOTc5MDgzZGMxJmEyPTk0MGY4ZmU4LTJhMzEtNDE4Ny1iOTVjLTQ2ZjZjZmQzNzVmNiZhMz0&td=dHJrLmV2ZXItZXhwcmVzcy1hbHJlYWR5LWZpbmVzdC5ydW4vc253ZGFydGY&lvc=fc594690

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?

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.

Instead of returning directly to my desktop when I close Firefox, this website opens: https://www.websudoku.com/ and I then have to close that before I can see my desktop. I do not want this to happen!!!!! How can I stop it?
