You look at it from end user perspective.
There are HUGE changes for devs, translators, addon devs, etc.
And now you will see new stable FF every 6th week, not faster not slower.
And you couple FF freezes with net availability? (my sometimes langs, not disconnection but still not working for eg 3s, and FF freezes in those 3s, also when it can not resolve url)
If you can reproduce this bug (know what to do to get this bug show up) go to FF bugzilla.
