As a PC user, Firefox has always been my browser of "choice" When I recently dumped Windows and came over to OS X, I wanted to continue using FIREFOX -- particularly for specific plugins that would not work on any other browser including SAFARI. For the most part, FIREFOX works fine under OS X....initially. However, I have read on many message boards about "memory leaks" within the browser, and I think I have finally experienced some of them myself. After a while, FIREFOX starts acting funky. COPY AND PASTE stops working. Also, if you type any punctuation keys (" ' &), the cursor jumps somewhere else in the browser page. Seems like there is some sort of defect in Firefox causing these problems with Macs. Anyone else experience these problems?
