Is there a HOVERSEE alternative for Mac on the App Store ? ( Hoversee extension was free but is now £7.99 ) Thanks?

Update: I updated Mojave to 10.14.6 and several Safari extensions no longer work. Apple don't warn you of that when they advertise the "upgrade". I got back most of them (or alternatives) but can't seem to find an app that will magnify when the pointer moves over something on screen.
