I've been running firefox as my main browser for years, but I've always kept chromium around for a handful of semi-trusted sites where I knew ahead of time the "block all the scripts" setup I have in firefox would cause trouble and I didn't want to bother adding to the whitelist.
well, as of yesterday morning, chromium has been crashing on launch 100% of the time, so I think that's the nudge I finally needed to dump it completely.
