Firefox still hangs/freezes after refresh firefox and disabling hardward acceleration

Firefox for Mac regularly freezes 10-30 seconds when visiting a variety of websies (Flickr, Tumblr,...). I did a Firefox refresh, disabled hardware acceleration, deleted all add-ons and continue to have the issue. If I visit the same websites using Safari or Chrome, I do not have the issue with hanging/freezing at all so the issue is with Firefox only. This issue has been going on for quite a while with various versions of Firefox. I had the same issue on a previous MacPro, I upgraded my MacPro in Jan 2015 and the issue continues after doing a reinstall of all software on my MacPro from scratch. Any suggestions to fix this issue would be appreciated.

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

If there is still a problem, Start Firefox in Safe Mode {web link} While you are in safe mode;

As a test, disable your protection programs.

I've called the big guys to help you. Good luck.

I don't use any protection programs so there's nothing to disable.

In addition to this, I enabled the Sync function. After doing so, anytime I add any bookmark, there is a delay of about 20 seconds. The bookmark gets added, sometimes right away, however, if I click on any other bookmarks, it's as if I hadn't clicked on anything and eventually the link that I clicked on gets displayed in the browser. If I disable the Sync then I don't have the delay when adding bookmarks at all. Any suggestions to improve this would be appreciated.
