This is the second day in a row where I'm casually browsing the internet (working on programming things in the background) and I notice my computer is sluggish. Opening about:memory in Nightly reveals that it wants > 600 MB of RAM. Now, I'm not on Youtube or whatnot; I don't even have the greedy Gmail open. Just two plain old web pages. According to about:memory, over 400 MB of this space is "heap-unclassified". Running GC, CC, and Minimize Usage buttons in about:memory don't seem to help at all. Any thoughts? This seems to be a recent problem...<br>
