Hello, I am running multiple FF profiles at the same time (4 at the moment). My problem is, that firefox loads my HDD at 100% and the whole system lags too much. I have tried to disable disk&memory cache, using firemin at the moment, but could not solve this issue. I can not RAMdisk ff, because my ram is only 4GB. (I relocated cache to RAM, but it did not help, though.) I have also tried to optimize browser this tutorial: http://www.blackhatworld.com/blackh...stances-imacors-automation-benefits-tips.html Any idea will be very appreciated.
