mb browser guard after latest update, does not keep saving the 3 tabs (ads, malware and scams) in the tab current website..uninstall or clear cache doesn't fix it. Except this, it doesn't recognize my premium subscription (device security is installed but it says upgrade to premium)

I love the privacy and security options it gives, but any site that uses ReCaptcha fails to let me log in because the plugin disables and blocks it, so I need to disable the ads/trackers setting for those sites.

good but poorly updated

Overall, it’s good, but I’d like to see more details in the statistics—specifically, the types of malware that have been blocked, not just the numbers.

Also, the 'Access your data for all websites' option is listed as optional, but it’s necessary for the program to work. I know you’ve been pretty transparent about how the data is used, but this does raise some concerns about data security as the company isn’t open-source.

This add-on is pretty good and helps prevent malware from being downloaded, as well as helps to avoid unsafe websites. However, today it started causing a massive memory leak whenever I opened my browser. My memory utilisation goes from about 40% with the add-on off to staying at 100% with the add-on active and websites will barely load. Hopefully this is fixed soon and I can re-enable the add-on.

Browser performance (with many tabs) suffers terribly if both Malware and Scams are switched on in addition to Ads/Trackers. For Malware, and for Scams, global switches are terribly broken: after switching off globally at one tab, I find both features wrongly switched on globally at another tab. I'll gather debug logs and discuss in the forums.

Also, the release notes here at AMO are wildly inconsistent with the release notes at the Malwarebytes website.

ad-block turns on by itself even when switched off in global settings. very annoying

Расширение интересное, но до конца не оптимизированное. Есть расширение получше. Возможно много памяти браузера занимает, мной не проверено, но потом как будет время, может, посмотрю.

The extension is interesting, but not fully optimized. There is a better extension. It probably takes up a lot of browser memory, I haven't checked it, but then I'll take a look at the time.
