Anyone know what's up with that? Why'd they release a 10.0.7 if they are on a fast dev cycle?

Mozilla has "Extended Service Release" versions of Firefox which receive updates for major security issues. v10 is the current (v17 upcoming). Organizations are expected to migrate over quickly once a new ESR is available.
