ok, thanks. it took something more than just creating a new profile (I have
had to copy the old one, delete the prefs.js from it, and reinstall a couple
addons which didn't seem to like the "hard-reset")

now, conky shows ~375 Mb with the about:home, espaciolinux.com, gmail,
google reader, and the about:config.

almost same addons enabled than before:
--- about:support - addons section (just the enabled ones)
Adblock Plus1.3.9
Lazarus: Form Recovery2.3
Tab Utilities1.1t
Webmail Ad Blocker3.4.2
YouTube to MP31.2.3

so, now i suppose i have to find which custom setting was causing that huge
memory use. i'll take a look as soon as i can.

English it's not my language. I'm trying to do my best, but forgive me if I
make a mistake.
