Please consider to read this article which may help you: Firefox uses too much memory or CPU resources - How to fix

Another point is this days modern browsers uses extra RAM and it's true. If you carefully see your screenshot, Firefox is consuming 526,760 K memory in one single process. But another modern browser Chrome is running on 7 different process. Which is in total consuming 782,222 K memory.

hi, your screenshot shows that firefox is using 526k while chrome is using 660k for the same tabs (you have to combine its processes for a proper comparison). those are normal values for modern browsers and you should only bother about memory usage once memory starts leaking (constantly increasing) or ram isn't freed once other programs need to make use of it.
