I really like the ability to highlight text then search Google for it using the right click menu. I know this is just robbed from Mozilla, buy they do say copying is the highest form of flattery.
I also like the ability to highlight text then see it translated into a different language in a little popup. Hopefully this is not patented so other browsers can now copy it but I am probably being overly optimistic here.
try the ubiquity firefox addon
It is a known fact that several JVMs out there do leak just by running. Even if you try, Java, with its language constructs, makes it difficult to control memory management and fine tuning.
Look at the WeakReference class and its family, if this is not a fine tuned memory management i don't know what it is. But to use it correctly you have to understandt the Java memory model. Also I have a some servers running a J2EE app and I currently have a 6 month up time. Last down time was a scheduled application update.
