Raymond noticed that code was inserted into the Adblock Pro extension to 'embed Flash objects' in the code itself which he called suspicious. This means that some level of logging is going on, and available on Google Analytics. First, that Google Analytics code was added to Adblock Pro. What weights more are Raymond's other findings. So, no attribution at all by the makers of Adblock Pro. It highlights that the extension is indeed uBlock Origin based. What more, the about page is still in the code of Adblock Pro, but it is not linked. The main difference is that Adblock Pro seems to use an older version of uBlock Origin than the original. If you compare the source code of both extensions, you will immediately notice that they share most of the code. Just use the real uBlock Origin: you get a more up to date version (1.10.0 as of writing), without any analytic hooks in the code base. I consider this suspicious.Īlso, the maintainer of Adblock Pro apparently does not want users to find out that the code was taken from the uBlock Origin project, the 'About' pane has been removed from the dashboard. Note the absence of privacy policy.Īlso, aside, whoever is behind this extension added another Content Security Policy directive which should really not be needed (the ability to embed Flash objects in the extension code itself). This is essentially the same code base as an older version (circa 1.7.4) of uBlock Origin, but with Google Analytics hook added to the manifest. Raymond Hill, creator of uBlock Origin, left a review for Adblock Pro on the Google Chrome web store that highlighted this, and other interesting tidbits. If you dig deeper, you will notice that the about page is missing, but that all other interface elements are a one to one copy of uBlock Origin. The core difference is the Adblock Pro logo that is added to the menu when you click on the icon in Chrome's address bar, and the logo on the settings page. If you install the extension and have used uBlock Origin before, you will immediately notice that it uses more or less the same interface as the popular extension.
