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.
