I have a Win10 laptop which it's performance is nowhere near a gaming machine. 3 Firefox flavors are installed on it (2 of them with a lot of extensions) and I don't remember the last time I've seen them crash or require force-quits. Don't have a good guess about the experience you have been through with it. About that mouse issue; have you ever tried a different mouse or reinstalling it's driver? I don't know Mac and I don't remember how it was on Linux, but if a mouse clicks or moves just a little bit, that wakes the system up on Windows machines. Till you got the random mouse clicks, it looks like it's a #1 suspect.
