As far as you can "trust" the updates that come, version numbers are not very useful. I generally see minor versions as bug fixes (number of bugs reduced hopefully) and major versions as major feature changes (number of bugs most likely increased). Now I just cannot tell anymore whether to upgrade or not. Believe it or not, the current browser* is running just fine for me. I am OK with a speedier browser etc, but not at the cost of more trouble. * Does it really matter which? (Firefox 5)
