Since the 73.0 update Firefox 73 loads SOME web pages slowly. For example, got to tesla.com and click on model S. This page barely loads. It starts but the graphic seems very slow. I tried loading Firefox 73.0 in safe mode, same problem. Safari loads everything quickly so not my internet connection. Firefox 72 (72.0.2) worked perfectly

Nice cars.

Many site issues can be caused by corrupt cookies or cache.

Warning ! ! This will log you out of sites you're logged in to. You may also lose any settings for that website.

If there is still a problem, Start Firefox in Safe Mode {web link} by holding down the <Shift> (Mac=Options) key, and then starting Firefox.

A small dialog should appear. Click Start In Safe Mode (not Refresh). Did this help?

While you are in safe mode;

Try disabling graphics hardware acceleration in Firefox. Since this feature was added to Firefox it has gradually improved but there are still a few glitches.

Already tried deleting all cookies on this site, cleared the cache as well. Same issue. Started with 73.0. Multiple sites do this. Again, Safari loads them fine

Start your Computer in safe mode with network support. Then start Firefox. Try Secure websites. Is the problem still there?
