I always get errors when I install more than two extensions at one time (without closing firefox once).
I could install one, but next extension returns error always.
How can I install many firefox extensions at burst.

always. I could install other extensions which I like one by one by restarting firefox one by one (I don't like this of course).
My environment is both Win XP and Win 2000.
