Good evening @AccioAbby90 ,
Do you happen to have any details on the type of laptop you are using? With the amount of input issues you mentioned, it's making me think that the laptop isn't being fully recognized, especially with both input devices (Mouse & Keyboard) not working.
Windows 10 is compatible with Sims 4; I know there was some recent mentions about optional security downloads that have affected graphical performance in desktop games, but this sounds less like a graphical issue and more of a performance/input issue.
I'm not sure what's going on with Firefox in that matter; normally the game doesn't do anything with the Firefox browser, so I'm not sure how it's related. Were other internet browsers working during this?
Note: I do not work for EA.
Kind Regards,
