Can't remove it to fix certain login issues and site access ever since I installed it, and it thinks it should be a permanent feature if Firefox when all I wanted to do was test it for a week.

Does what it says but upon opening multiple pages, or if running a page for a lengthy period, it causes memory leaks up to GBs worth of RAM.

Macht enorm viele Probleme Websites laden nicht mehr das fuckt einfach ab nie wieder!

This extension is among the best for online safety, and I believe truly lives up to the moniker of "Browser Guard". It catches an innumerable amount of unsafe sites before you even open them, and blocks a fair few trackers as well.

I would have rated it 5 stars, but as of late visits to YouTube have had reduced protection on by default, which I imagine is a result of pressure from Google wanting as much of your information from it's biggest social media platform as possible. I won't pretend to know what's going on behind the scenes to have led to this, but what I do know is that this somewhat tarnishes the good name of Malwarebytes in my eyes. If they've bent the knee to google, my trust wavers.

I generally like this ad block/browser extension over the larger one's on Firefox. Without naming them, this Malwarebytes Browser Guard does just as well as them while having a nicer interface. While you can't use filter lists here, having more doesn't mean it's better. What is here is just as good as the others.

I love the Check Marks when I'm searching things on my browser. I rather have those over clicking on a site just to find out its blocked but some filter. Those marks have saved me those seconds as I would know it before I even tried click that link.

1 small issue but it doesn't bother me, it might with others though. It does block YouTube ads on website as well as any videos although on videos you can see a second or two of the ad before this extension "kicks in" and speed up the the timers playing the video after.

Over all this is a fantastic app and is now being used daily by me.

I would love to continue using this add-on, but it takes too much RAM. It does not show us what sites to ban, either. What do you care, at all, besides your money?

This extension is fireee!! Thanks malwarebytes!!

I've used Malwarebytes for years, and never had a problem. Today, it blocked literally every website I had open, and then closed them all when I removed the extension. I usually keep a lot of tabs open for research, and now I'm going to have to look up hundreds of items from scratch.

Nice intention but too many websites just don't work properly when activated. Especially the Ad/Tracker Blocker practically disables browsing.

Mate, no other add-on stuffs up as much as this one. Today 50 of me tabs got blocked; I could only remember about ten off the top of me head – the rest are gone for good. That’s why I’m chuckin’ it today; the risk’s way too high. A couple of times a year somethin’ goes pear-shaped, so I gotta switch the add-on off. I’ve had a bloody gutful now!

yep nice .. every single website was blocked on my tab. I googled to look how to unblock everything with one click and did everything, even checked for database updates and nothing worked ... everything is still blocked .. had to manually unblock everything .. thank you very much for this work. Something that blocks everything out of the blue is the last thing someone wants.

Was great until it decided to block every single one of my tabs. What's wrong with reddit and google searches? And it didn't just block them, 80% of them couldn't be rewound so I lost most of my groups. Seriously, quality check your updates for crying out loud.

The latest version of 3.3.6 is a mess. It blocked every single tab I had, even the pinned ones. The version was last updated Sept 30, 2026 (today is Oct 1st). It was working all day and then out of the blue it blocked every single tab. What a mess.
