this is the set I've been using with the 'new' Australis UI POS versions of Nightly and Aurora, trying to reduce the amount of memory Firefox is using. 1.7 GB and 50% of CPU is insane.
add-ons that do not work, do not work as presented or just Suck. These are not add-ons that I've used, like, but no longer updated for the F*ed up Firefox versioning system.
addons i've found while looking for something else, but found to be worth looking into,,,, later when i'm Not looking for something specific to accomplish whatever it is i'm trying to do
these are addons i use, have used and find useful, but are Not Must Have in a new installation.
these are add-ons I install on every 'fresh' install. some because I like 'grey scale', a non-distracting, minimalist look some because I code; css, html, php & 'hack' UI xul, 18+ hours a day
