I don't see the same thing here with 10.3.3. Safari spikes while 
loading the page, but CPU usage drops down to 8-15% after it's done.

Maybe it could have something to do with some of the extremely long 
lines in the HTML source for that page? I'm not sure if those long 
lines may make it harder for Firefox and Safari to parse and render the 
page? Also, each class is a table. Tables can be notorious for causing 
performance issues. All the HTML comes from doxygen, and it's likely 
that generating a page with the sheer volume of VTK classes just 
creates a page that some HTML engines don't render efficiently.
