Firefox's plugin run in containers (who know what they mean by "plugin security" anyway, does that mean click to play on java?) and Firefox manages its own memory and has different memory segments for each tab (some kind of sandboxing). It's also hard to argue what's industry standard in this area, and whats not, because well, there's no real industry standard. Proof of it is that the 3 leaders with close enough market shares implement different things. Finally, where's Opera, as usual.
