There aren't any memory leak issues in Firefox. I have been using Firefox since Firefox 10 and it has made huge strides in memory performance so much so that it beats every browser out there on memory benchmarks. In fact, on the mac, with the same number (34) of tabs, the same content, no add-ons or extensions, Firefox takes 600MB - 800MB, Safari takes around 900MB-1GB and Chrome takes around 900-1.2GB. I use these browsers every day and I have the same results every day. I have the same tabs open now in Firefox, all 34 of them and it's only taking 740MB. You just can't beat that. It's really awesome.
