My keyboard regularly locks up using Firefox. I tracked the problem down to having upwards of 40 Firefox processes running in Task Manager. Disabling them or restarting Firefox only works for a few hours before the problem recurs. Several people here recommend disabling "Use recommended performance settings," which should give me the option of selecting the max number of processes to be running. However, when I disable the recommended performance setting, the hardware acceleration option appears, but not the process number selection. I'm finding no way to set the max number of processes. I'm hoping for a work-around to that, or a different solution. Thanks. BTW, I also notice excessive processes running when I use Chrome. I'm concerned why this is happening on both my browsers.
