The adblocker test isn't very thorough. It just checks whether an image can be downloade from gstatic.com. It told me that I don't have an adblocker installed when in fact I have ublock origin with the setting that it can download images from gstatic.com
1. Tries to load a file called ads.css which is usually blocked in default installations of many blockers relying on Easy List.
2. It uses gstatic.com to check if acceptable ads are being allowed - gstatic.com is whitelisted by Adblock Plus, so we test for it and warn users that acceptable ads are being let through.
We're going to be updating the detection to detect use of other blockers.
