OK. Please reduce the problem down to a single app, like just Firefox. Now, please let us know: 1. The version of Firefox; and 2. What web page(s) cause the biggest problem.
I think my list of planned fixes for Ubuntu 18.10 [1] will be the best avenue for helping you because the Celeron 847 has a passmark [2] of 936, and I estimate gnome-shell presently requires a CPU with passmark around 5000 or more to run smoothly. Obviously we need to get that number down a lot by optimizing gnome-shell in future...
