All browsers can clear their own browsing history, temp files and cookies. The modern browsers have InPrivate/Incognito mode to prevent saved browsing habits (local only). HotCleaners' C&C is a copy of built-in browser features, not used extensively to test all it's features.
Abine (DNTMe) and Disconnect.me both have a good reputation, as far as I know. The rest are possibly questionable in someway, as I explain below.
- AdBlock Plus has an optional white-list of it's own trusted sites. Using a fork-of or another AdBlock extension is advised for better control of your privacy.
- Ghostery (the online privacy addon) has the optional GhostRank (Evidon - Online Marketing, Web Analytics)
Others have mentioned:
- Bitdefender TrafficLight, by default anonymous usage reports are switched ON.
- Avast Online Security, by default anonymous usage reports are switched ON (aka CommunityIQ), and optionally SafePrice where you 'receive shopping recommendations on relevant sites', this setting is partially checked by default without avast AV being installed.
IMO, less extensions = better control of privacy, I recommend regarding guides for social networking security and privacy, because that is one less extension required to manage your online profiles. And if you can be bothered review (or check for any controversy) regarding it's Privacy Policy.
I have DNT browser settings enabled for all browsers (even if it's useless / ignored), and use Adblock (Chrome), AdBlock Edge (Firefox) and no extensions installed for IE11.
