Does Firefox manage the priority of processes in Windows 10 ?

Posted

As Firefox often responds slow to my actions on my Compaq Presario CQ5303NL I have tried solving this by raising the priority of some of the 8 to 10 firefox.exe processes from Normal to High (with 3 Firefox windows and about 20 tabs open). This is done with the Task Manager. However the last month every 10 to 20 minutes the priority settings are reversed and about four firefox.exe processes are then set to Low priority at regular time intervals. This also seems to result in slow response to mouseclicks. Are you aware of this phenomenon? Is this something Firefox does by itself, or is this intervention coming from Windows 10. I notice that when I put explorer.exe in high priority, this lasts till shutdown of the computer, as with other manageble processes.

This is not a serious problem. It's more questioning what Windows is doing with Firefox. (memory is 6GB)

It has been the cause of my computer, an hp mini tower with 4Gb of RAM, to freeze up or hang. And once I change the Set Priority to high it picks up almost immediately. So my question is why make it jump to the lowest setting? Why not leave it at NORMAL?

Firefox will manage the priority of processes in some instances, however, testing has found it to have very little actual perceivable impact. I'd just let it do whatever it is doing.
