I keep getting notification from firefox that I need to download mcafee that I have a virus I have all ready done a mcafee removal did no have it to start with can not use fire fox as it continues to give me the messages that wont stop i have turned off notifications but that isn't the answer I have malwarebytes and windows virus protection what now.

I am just burned out with Firefox and not sure why I should continue to use it instead of some fork or Chromium-based browser.

It seems like every update brings some new GenAI/LLM component that is auto-enabled and difficult to disable. I do not want GenAI/LLMs in my web browser. I have dropped nearly every other application or software that has forced it on me and included it in their product. I feel like I'm trying manage a Windows system having to follow blogs to debloat, restore privacy, and restore security. GenAI/LLMs shouldn't be in my web browser. And, they should be opt-in, not opt-out in some confusing mix of GUI and about:config madness. If GenAI/LLM is so great, then make it an extension or a fork then let those folks use it from there. Don't bake it into the web browser.

I continue to use Firefox for uBlock Origin but I guess that would be possible with a Firefox-fork. However, I am just tired of having to continuously manage my Firefox browser and battle websites that only support Chromium-based browsers. If Firefox actually seemed intent on improving security and privacy then I could find the motivation but this GenAI/LLM nonsense seems the point of no return.

On my Android phone, I've switched to a Chromium-based browser given the poor state of security and hardening for the vanilla Firefox. I keep IronFox on hand but it is just easier to surf the web with a Chromium-based browser due to many websites just working better. Why should I deal with the pain and frustration of limited Firefox support when Firefox isn't even keeping up with security hardening?

As for desktop, the Firefox browser just doesn't seem as snappy or stable as I would expect. Firefox for Linux is still not supported for Slack Huddles. How is it 2026 and Mozilla/Firefox are still not fully functional with one of the major business chat platforms? Yes, I know this primarily a Slack and AWS-Chime-SDK problem but it is also a Firefox problem because there isn't much that a user can do. I've tried to prod Slack and the AWS teams numerous times to support Firefox but they've just done nothing. I also see nothing being done by the Firefox team, too.

Another example is the EdgeSuite CDN. Nearly always they block my traffic when I use Firefox. Switch to a Chromium-based browser and EdgeSuite is much less likely to block me. This is fairly consistent for the retail and financial institutions I use.

As far as I am aware, many of the security concerns brought up by Madaidan in 2022 still hold true for Firefox today, especially for Android and Linux. If this is no longer true, then it might be good for the Firefox team to post a rebuttal or update clarifying the current state of Firefox. The average users such as myself only see the Madaidan blog post and have to take it at face value. https://madaidans-insecurities.github.io/firefox-chromium.html

Anyway, I don't see a way ahead for me and Firefox but maybe you can convince me. It just seems like Firefox and Mozilla have lost their way. They no longer seem focused on security and privacy. Instead they're forcing privacy, security, and system resource disasters onto their userbases, just like Microsoft, Google, and every one of the major tech firms. I just don't see why I should use, promote, and even support Firefox going into 2026.

I have received 3 system alerts, all from Mozilla Firefox (I use Firefox as my default browser). 1) System is infected!---click on d45n9f8ko90s738b610.gsx-protect.co.in 2) ZEUS.2020 Trojan detected--with same directed site 3) System Alert!---with same directed site.

I use McAfee as my security system. They recommend going to Firefox settings and disallowing random site connections. How do I get my system running again.

Latest McAfee scan shows 45 entries deleted and 2 browsers reset

I was asked to 'Allow Chatgpt.com to store data in persistent storage'. Would that add on the risk of having my data being more exposed and kept by stakeholders not of my own choice?

Hi, I am using Firefox exclusively for my work Claude account, I only check my usage on it. Today, I noticed Firefox silently installed a webapp under $USER/AppData/Roaming/Microsoft/Windows/Start Menu/Programs, and it has a Claude webapp, which I neither click any install or add to my menu. I found it extremely concerning in terms of privacy, and I am wondering if any other people have similar experience.

Pop-up blocker Inable please because of some of site setting pop-up blocked. Please open pop-up option in firefox browser site setting allowed.link text

I have picked up some bug(s) on my Firefox that I cannot figure out how to get rid of. With a Firefox ID I have warnings of 3 Trojan Virus detected, Virus detected, hard drive infected, secure data notice and system alert. I also got a warning that my McAfee protection had expired which is very strange. Since switching over in 2010 from Windows to Linux I have never had protection of any kind and unlike Windows have never had a single problem. In addition when I was using Windows the protection that I had was never McAfee. I suspect that these warnings are not from Firefox given the misprints, spelling errors and the poor English. It is likely phishing from some third world country. How do I get rid of this obvious garbage permanently? Many thanks! Kris

Hi,

Hello This evening as I was going to pay for a book on a site well known to me, I notice that I don’t see a lock to the left of the address. I read your page 'Mixed content blocking in Firefox' after seeing that its little French sister was not up to date and it seems that it is the version of Firefox installed tonight that is behind this big change. Even my bank’s site no longer shows padlocks and it’s destabilizing. Why such a change without explanation??? I only read information about the split view in the same tab (which seems very useful) but nothing about this disappearance of the lock... Can you confirm that it is indeed the version from tonight 27/03/2026 that made this change at first glance worrying.

Thank you in advance and have a good day.
