Wow!! This extension has blocked over 4000 Ads/Trackers since I downloaded it a week ago. I navigate a lot of different websites because I’m an online college student, and this has been a game changer. No more annoying ads! I also recommend the separate Malwarebytes software, that can be downloaded on their website, because it can scan your computer for potentially dangerous files, to prevent viruses & malware on your PC.

The best protection for my computer that I have found yet. I have tried others, but Malwarebytes gives me the reassurance that they actually are working round the clock to keep me and my information safe. Easy to install, easy to use, and they also let you try things at reasonable prices.

I absolutely love this extension — and Malwarebytes as a whole! This company has saved me so many times, it’s honestly funny. From accidentally downloading straight-up RedLine stealers to brushing way too close to disaster, Malwarebytes always had my back. Total lifesaver.

I use Linux and started using the Malwarebytes Browser Guard extension fairly recently. My browsing speed has noticeably improved (it was already faster than expected before, thanks to some fine-tuned browser settings). On top of that, the traffic is now filtered much more cleanly, and the browser feels lighter and more responsive 🙂 Thanks!

Works great with Vivaldi browser, blocks suspicious websites and redirects when I’m watching anime and movies on “certain websites” if you know what i mean. It also blocks sus ads so i don’t get jumpscared by THOSE type of ads anymore lol.
