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?

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.

Error Console wrote:No chrome package registered for chrome://adblockplus/skin/adblockplus.png .
No chrome package registered for chrome://flashblock/skin/flash-on-24.png .
