After doing the upgrade I was also having issues with FF but they were slightly different. FF seemed faster overall accessing sites but while sitting idle it would occationally (like on a clock cycle) chew up to 150% of my cpu (hyperthreaded cpu). After copying ~/.mozilla to a backup and eliminating all functional and nonfunctional add ons, the cpu issue disappeared. My times with the dig references below are 17ms & 9ms respectively.
