rapid and excesive resource use

[Stan Osborne]

within minutes system is out of CPU cycles and Memory. After a few hours of no active use, but staying logged in with firefox active, disks are churning and not able to type, nor does cursor move. System is locked up, must power off and reboot.

At times soon after reboot, I have found 9 firfox processes active, yet only two firefox widows are active, each with five tabs.

Could it be that inactive tabs are still running, as if a user could see their content? Some news web sties are now poping up video windows that automatically start playing.

Only the processes supporting the visible tab(s) should be active. All other processes should go to sleep by setting a lower process priority so they go dormant and are swapped out.

Stop memory utilization from growing and growing and growing. Bloatware is bad.
