Browser Checkup parasite-extensions that make your browser slow and clanky. Get examed by the Doctor & make your browser young again
The world of browsing extensions is vast - ranging from simple spell-checkers and shopping assistants to full-blown, in-browser, CRM systems. Most make our lives easier, but some have undesired effects from clogging the browser's resources to injecting ads,  violating privacy by planting trackers, to creating borderline malicious activity.

Doctor's "Browser X-ray" treats your browser to detect such parasite-like extensions.
Get a quick examination by the Doctor and revitalize your browser to make it run like the day your first installed it.

Doctor's free version allows on-demand scanning and "healing" for known bad extensions. 
Doctor's premium version performs scans automatically and periodically without any user interaction. 

* Update: The premium version is currently unavailable due to store policy changes regarding in-app extensions payments.
