Why is Firefox for Mac stalling on many sites recently?
In the last couple of days, my Firefox for Mac (37.0.2) has been stalling on many sites, with the spinning wheel icon just rotating endlessly to show unsuccessful processing. This hanging action occurs on several sites where I'm going into inside pages, a problem I almost never have but now is frequent. Is this some kind of temporary or known issue? I don't want to have to go through Refresh, especially since i noticed someone else commented that it didn't resolve a similar issue. But something is definitely wrong, and is making use of Firefox extremely frustrating if not pointless.

Try to disable IPv6 (check for other possible causes as well).
