I don't know what the deal is but my 2012 2.3Ghz Mac Mini seems to constantly choke on Firefox. I'm not sure if it's Firefox or if there is an issue with the computer. I just opened Firefox from a fresh restart and within 2 clicks it was pinwheeling. It lasts anywhere from 10sec to 40sec at times. Anyone have a fix? I've googled and searched these forums. I've upgraded my RAM today to 16gb of Crucial RAM and it didn't help, previously I was using 1333Mhz 8gb Crucial RAM that I pulled from my 2011 iMac, thinking maybe I just needed more RAM, I do a bit of video work and often convert using Handbrake. I've also put and SSD in the Mac Mini Crucial M4 256gb. Any advice would be helpful.
