I had the same problem with Safari, solved it by using Mozilla Firefox and adding the UBlock ad blocker extension which blocks the anyclip video ads and has the additional benefit of blocking most other ads too.
Unfortunately UBlock is no longer available for Safari
I am seeing this problem as well. I don't see the freeze on Firefox, however, even without ad blocker there.
srye21 thanks for posting that video ads are the cause of the site freezing. I've been emailing support and they have been claiming I was the only user having problems with Safari on SA! Now they need to fix this. SA works on Chrome but I see no reason that I should switch from Safari as my main browser just so SA can show me video ads I don't want to begin with!
