firefox 29 windows 8.1 update (1) - IE all M$ updates installed logitech M570 mouse my mouse back and forward buttons no longer work in v29. i tried FF safe mode, i tried with logitech setpoint 6.5 enabled and disabled, resetting setpoint. i don't want to "reset firefox" because i just did a fresh windows install and fresh firefox 28 install before upgrading to FF29 a few days later..... BTW the back/forward buttons work in all other installed programs as well as FF28 in my windows 7 machine. thanks in advance for any replies....
