it seems i get a bug with firefox 2.0.0.x on winXP.

i use firefox with a authenticated proxy server and multiple windows
with multiples tabs and password are ask a lot of times.

For example, when updating firefox, firefox restart:
Ask for master password, next proxy authentication, do extensions
update, display first windows, ask again for master password, ask for
pre-filled proxy authentication, next tabs and windows, ask again for
the same things (ok for proxy auth but not for master password)

is it normal ? planned to change or a bug ?

logical would be asking master password once with a lock for update and
all tabs/windows. best if it could the same with proxy authentication.
