User reviews

A different extension I used to block pixel code in the past (PixelBlock) no longer works after the chome manifest V3 update, but Gblock does and it's even better! I was a bit surprised by the low number of users and ratings so (with the help of a little AI) I went over all of the code that goes into this extension, it fully checks out! I was a bit concerned by the proxy that receives URLs that you click on in emails (that is used to prevent tracking), so I contacted the developer and the next day there was a profile setting to turn it off (I only turned it off for my work account as it is a good feature to keep on). Great develper, great extension, highly reccomend! Out of curiocity I also checked the code of the other extension I used to use and Gblock does a better job, less chance of it missing trackers.

I checked my emails with a tracker detector before and after installing GBlock—the difference is insane. This thing really works!
