I guess it would be somewhat rare (I am running Ubuntu) but not that rare.
I'd be interested to know how this can be, since nothing in the info it gave back looked especially unusual.
I've long wanted to build a WebKit based browser that simply lies in response to all of those evil questions. Add it to my backlog of Important Projects, I guess.
I haven't installed any weird versions of plugins, I assumed they would be tied to whatever chrome version I have.
And Ubuntu isn't rare enough for me to be the only person using it (especially on EFF).
Going to have to experiment with this a bit.
It doesn't have to be unusual, it just has to vary slightly from machine to machine. It's the specific combination of those slight variations that's unusual.
