OSX Yosemite

Lured by the promise of more powerful performance I got the free upgrade to OS X Yosemite and it is a nightmare. I don't know a lot of fancy computer stuff, and multiple times a day I'm being told that Safari can't find the server of a particular site. Then, a minute later, it will go through. Ordering a few things from Home Depot this morning was a chore.
I did some research, enough to see that some others are having similar issues with Yosemite.
I hate it, but it is obvious that sooner or later I will have to wade through a bunch of stuff and learn how to do the fixes.

Most of my mac customers like when I suggest using firefox for mac. Safari and chrome cause many headaches.

Thank you I will look into Firefox
