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 AutoPager0.7.0.0 InstantFox2.0.8 Lazarus: Form Recovery2.3 NoScript2.1.2.9rc1 Personas1.6.2 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. 2011/9/15 Mike Hommey <m...@glandium.org> > On Thu, Sep 15, 2011 at 12:10:16AM +0200, niky 45 wrote: > > ok, some more tests. > > > > i was thinking, which extension can use so much ram?? so i had started > > disabling te obvious ones: fasterfox (has some cache options that would > use > > pretty much ram), autopager, lazarus... > > > > the i thought: hey. what if i dis-enable ALL of them (again)?? the > results > > of the previous test, showed me that an idle measure of ram used (i.e. > > having firefox opened for a couple minutes), are not always relevant. > many > > times, opening a (blank) tab, almost duplicates the ram use. > > > > so, i had disabled all of them, and opened some tabs: gmail (writing > this), > > the addons manager, the about memory one (which i show in the attached > > screenshot), gogle reader, and a forum i usualy read (espaciolinux.com). > > > > at launch time, conky read ~300 Mb, a very good measurement. after > opening > > these tabs... voila!! now conky reads 1.31 Gb, and you can see (in the > > attachment) that the about:memory gives similar data. > > > > in the second attachment, you can also see the addons: none enabled.
