closed tabs keep running in the background
When I close tabs, and the computer stops working and I check the Task manager it turns out that firefox still runs 20-30tabs in the background when most of then have been closed and have just 4 running!!!
This occupies 100% of disk and CPU, and thw laptop stops functioning and freezes!!!!!!
And this happens all the time! How do we make firefox actualy close the tabs properly?? Without having to dig through task managerto close them again one by one?
Windows Task manager doesn't show tabs, just processes.
You can check the about:memory and about:processes pages for info about all Firefox processes. See also the about:unloads page for info about the tabs.
