Extension: DuckDuckGo Privacy Essentials instability observed on Manjaro Linux

There seems to be a problem with DuckDuckGo Privacy Essentials
2022.6.15 extension on Brave Version 1.40.105 Chromium: 103.0.5060.53 (Official Build) (64-bit), tested on Manjaro Linux 5.15.48-1-MANJARO. Test scenario; log in to Twitter and follow someone unable to follow & session management all over the place (getting logged out). Local storage reset no help. Unsure about any other OS at this time.

Disabling just this extension, everything works fine.

Also, unsure if it is related, but earlier observed a strange occurrence in SSL certificate for a website that appeared to have expired. After disabling the DDG extension, it is no longer the case.
