Can anyone shed some light on why Facebook is such a resource hog on Chrome and Firefox but not on Edge/IE? It only seems to be on the home feed whereby CPU usage will ramp above 50% on Chrome and up to nearly 100% on Firefox - both latest builds and both with or without plugins, they don't cause or affect the CPU usage when turned on or off. Oddly, when on my profile page, the CPU load drops to a normal browsing level. After lots of web searching, I'm not the only one that's suffering with this but there seems to be no obvious solution other than "don't use Chrome or Firefox", which isn't a solution. Has anyone else come across this, or could anyone please test and suggest a solution?
