I actually use fakespot a lot, but will never install an add-on for this.
I got that notice a few months ago, but I didn't use either button on the bottom. I used the X on the top, and haven't seen it since.
I thought we were done with the age of Toolbars, but here we are, back there. An app or add-on for every damn thing. No, I don't want this integrated into my browser. No, I don't need your HTML5 app on my phone to do less than the webpage does. No, I don't want your spyware app to view the one-off Twitter, Facebook, or Instagram link a friend sends me. No, I don't mean 'maybe later', I mean 'no forever'.
