Just wondering... does anyone else have Firefox corrupt the prefs.js file occasionally (about every 3-4 months)? If this isn't common, its probably my choice of add-ons.

Thankfully, Windows Server 2008 has a feature called Previous Versions [1] (a feature that is also in Windows Server 2003) where I can pull the Firefox profile stuff from a snapshot. However, I'm wondering if this is just a fluke or something that other people have encountered.

[1]: Of course, Time Machine is a cooler name for the same thing, but regardless of name, snapshots are a cool feature in any OS.
