I've reinstalled Malwarebytes Browser Guard and the improvement is undeniable; it works great now.

It would be helpful if Firefox made updates more visible, since it’s not always clear when a new version is available. Still, it’s good to see the extension running smoothly.

Thanks, Malwarebytes! I also hope you release a mobile version someday; that would be fantastic.

Old review:
(I've been using "Malwarebytes Browser Guard" for a couple of months, and I've noticed a few issues.

There's no doubt it does a great job blocking malicious sites, trackers, scams, etc. But it also slows down the browser when I have several tabs open or when loading more than one tab at the same time. After testing, I noticed a pattern (at least in my case): the more images a website has (Google Maps, ArtStation, Pinterest, etc.), the worse the browser's performance gets. So, I went into the extension's settings and disabled its three main features (Ads/Trackers = Off, Malware = Off, Scams = Off) for each of these sites, but to my surprise, it didn't work—the sites were still slow. I assume that Malwarebytes is still scanning all the links on the site, but the fact that this happens even after disabling those features feels like a big flaw. Hopefully, it's just me not knowing how to use the extension properly, but for now, I had to disable it.

At first, I thought the issue was related to my browser's cache or something similar, so I reset the browser, and that fixed it temporarily. However, once I reinstalled my extensions, the issue came back. After testing them one by one, I found out that the problem was caused by "Malwarebytes Browser Guard."

This wouldn't be such a big deal, but I use the aforementioned pages a lot and at least I think that many users also use Google Maps and from my experience, that's where the issue is the worst.)

I have used Malwarebytes before it sold to new owners, so far it seems one of the best that I currently use. it may have hiccups sometimes, but it is resolved through support.. also recommend for PC, phones..

Add-ons meravigliosa, funziona benissimo!!!

Excellent!!

Now youtube is not playing because the ads are blocked, I would like to add an exception for the domain of youtube (by decision, I mean, an option to add domains)

nice
better

I feel safer with this extension. I also have paid subscriptions with the Malwarebytes firm on every computer I have ever owned for many years now.

Now I can trully use Firefox as my main browser, I always use malware guard.
