Haven't really encountered any big issues with it, it works like expected from what I can see. I've been using it since November 2022 on Firefox and before then on Chromium.

Ok

The extension works most of the time, but every time I go to weather.com, it freaks out and I just keep getting redirected, with the numbers on the icon going up like crazy. I've cleaned my cache, I have the latest version of the extension, so I don't know what the issue is.

This plugins blocks my own website for phishing for years after using it for a few months, meanwhile my website is clean and I have even checked using other malware detectors and 3rd party scanning tools!!!

It's slowing down the browser's site loading speed massively. Deactivated.

Anti-garbage designed specifically for the browser itself was long-time needed.
MB filled the niche quite nicely i'd say. Thank you MB staff.

It's a good antivirus, but it uses too much ram!

MwB Guard slowing down the browser and websites load... and don't know why the extension is using 25.85MB storage size, you should improve the extension to works better and to use less data size.. otherwise is a great extension does exactly what it says and fits nice with the MwB Premium, besides of issues i have with it. :)
