OT, but: Firefox 4.x is a nasty pile of alpha-ware (at least, on Linux x86-64). 5.x wasn't much better. Upgrade to 6.02 for something more stable. Firefox 4.0 drove me to use Chrome as my primary browser, although 6.02 is stable enough that I might even switch back by 7 (or 8.. or 9.. or..) (and I still use Firefox for development because nothing can touch Firebug)
