As far as i know, latest official mozilla builds includes PGO on linux as well, and so it is on archlinux.
Can't see why other distributions like ubuntu shouldn't do it too, nor i know if that statement is true.
How about you start writing with full sentences/words en way... les.... dots.....
That would certainly increase the readability of your posts in general.
But maybe its a authentication check. Its only true "Qaridarium" if there are wrong stuff in it with many dots.
If Bridgman hack my account and try to write here as "Qaridarium" he will fail because he can not write like me LOL
because he is not so brain-death like me.
its like a water mark protection.
