@ anytime:- it does leak in a lot of memory. With ABP K-meleon consumes 35MB more than its usual in my tests with K-meleon. The same carries out with any other browser too but the usage may vary. You can google its issues with various browsers. U'll see :-) Chrome, firefox, opera
Its issue has been mentioned in K-meleon forums itself
