I mean, I was listing stuff one person can do on their site to detect if visitors have a type of extension or not. If I can do that with a couple hours of work I am not surprised at all whith what a major social network like linkedin can implement. I don't know what linkedin does and I don't plan to read their code, I did not even read the article tbh
Well, that's a pretty useless approach for tech discussions, because this kind of attack is explicitly not possible on Firefox.
Also, extrapolating such a broad statement from the simple fact that it's possible to unreliably detect the presence of a single broad category of extensions is a huge reach.
