good Rated 4 out of 5 stars
i've opened 20+ tabs and from time to time i got restart ff cause of its memory abuse. not to fill it up at start up i cancelled the network so no tab could be loaded and ram is "fresh". i can reload every tab if i need it - my sort of bookmark :)
absolut load control offers second solution for that, especially for tabs that try to load till eternity like yt i can klick stop all.
i wish there would be a button to freeze all tabs except the present tab in front. Wouldn't this give the actual tab the full processor power respectively 'calm down' all other tabs to give back more cpu to the front tab??
this would be worth to think of i mean :)
