Fixing Firefox memory leaks

If you’ve been plagued by Firefox memory leaks like I have, you need to read this article which covers the browser.sessionhistory.max_total_viewers preference value. This concerns how much cache is reserved for browsing. The default setting expects you to page back up to 8 pages. Because of tabbed browsing, I almost never page back, so I’ve set this from the default -1 (also equivalent to 8) to a value of 0. My memory usage is now down by 33%. Thanks for the tip!!
