Browser Guard works great, I haven't been using it that long now, but I have had a lot less problems than I used to have since I started using it and will continue to use it. I highly recommend it to anyone who is tired of getting hassled or is worried about anything weird coming to their PC.

Ok

Blocks trackers as expected and I have this as full protection paid software on my PC & phone.

I'm a skilled PC user, but this add-on has helped save me from accidentally opening scam/imposter websites several times. Since adding it to Firefox, my SUPERAntiSpyware scans have also picked up way, way less PUPs and trackers to clean! It's definitely effective and I consider this to be a vital add on to get whenever I've had to reset a device or use a new one.

The only problem I have with it is that it has no accessible whitelist option. You have to go into your browser's add-on settings and completely disable it if you ever find that it's blocking an important popup. Though that's rare and it's still more than worth the benefits.

Ok, but blocks images on some news websites. I don't see a way to white list sites, so I disable the extension. I'd give a higher rating if I could find out how to white list selected domains.

Works well and as expected ... This is enough

Kept getting multiple popups from Malwarebytes trying to get me to subscribe to a paid service. Finally the addon interfered with my email and ability to get online. I tried to uninstall the Malwarbytes software but kept getting 'wait for other program to uninstall' message. But I wasn't trying to uninstall any other program. Finally after opening in safe mode - the computer very sluggish the entire time - I was able to uninstall. After rebooting a couple of times in normal mode things finally got back to normal. Whether a but or a deliberate attempt to compel purchase, this program is terrible. Does it make your computer safer? I don't know, but if the computer won't run, what's the difference?
