I have many laptops. But only use two ATM - on the Dell core i5 6GB ram, Firefox runs smoothly. My previous daily driver a hp envy core i5 also has no issues with Firefox. Chrome was SLOOW on the Envy and pushed me over to Firefox. It's the Packard Bell (detachable screen Atom x5-Z8350, 2GB ram) that I'm having issues with. I don't know if it's because I'm always on battery saver mode. Disabling all my extensions didn't help. >Firefox is much less resource intensive than chrome I have the same experience with both core i5 laptops. Installed Opera - not chrome on the detachable. I can't compare the memory usage btw opera and Firefox because I've got more extensions running on Firefox. Please note, I once disabled all extensions but it made no difference.
