I have Linux Mint installed on 3 computers at home, and all of them are almost unusably slow whenever Firefox is open. Here is the output from top:As you can see, Web Content and Firefox are collectively using up nearly all of my CPU, and more than 50% (4GB+) of system memory.I have never had this problem in the past with Debian or Ubuntu, but it is occuring on every computer I've installed Mint on so far. This extremely high (near total) CPU/memory usage is constant, and is rendering my computer unusable. Does anyone have ideas about how to fix this? If there is no fix, how can I keep this Web Content application from running at all?
