I copied this code from a site, which alows one to detect installed extensions with javascript, and possiby act on these results. Which is a very disturbing thing because it can have huge complications. One could for instance redirect users based on their installed extensions, block them, or show them other content, and maybe... maybe: with the detection, abuse could be possible if they find code flaws in the extensions.
below a few lines with which you could detect a few extensions.
So what is going to be done about this?

Re: They know which extensions you use...
I'm getting below messages now when logging into my GMail account. Probably javascript.options.showInConsole needs to be set to true to see it.
