This is named browser cleaner, but does not clean your browser all the way. Cleans all five different things it says, but that cleans it only partially. Leaves all site data untouched, so i can't think any reason to use this.

if you want to "clean" your browser this aint it chief

(using firefox version<90 windows11, some other browsers may support all the 9 other cleaning features)

Doesn't support whitelist without extra charges. Will delete all cookies regardless of "allow" settings in Firefox.

When I checked the cache status in the FireFox options page, the amount of cached data never dropped, even after the add-in said it had been cleaned.

Einfache Benutzeroberfläche, aber nützlich.
