I've been using Linux for a lot longer and on variety of hardware. I don't have this problem on my desktop, but the laptop and the trackpad are rather fresh, so maybe somewhere there's a bug or something. For some reason whenever there's a problem it's always Firefox, and rarely if ever Chrome. Example of another problem I had recently - websites like whathifi, tomsguide and a bunch of others were using 100% of one CPU core on Firefox, no problem on Chrome.
