Home Forums Read-Only Forums New Users Safari Update from Apple inoperable in Mavericks

I downloaded a Safari update from Applestore updates yesterday. I have been running Mavericks in a 2012 MacBook Pro. I have never had a problem like this before.
Try to open Safari now and it half way opens a web page and crashes.
I tried replace a previous version from my Time Machine back up disk and "of course" I cannot do that because Safari is now part of OSX and cannot be deleted. Or can it? So I would have to revert to Mountain Lion which I will not do. I am now using Firefox.
I don't want to upgrade to Yosemite because I have just read too much bad publicity about it running slow and running Macs slow.
Is there someway I can beat this situation?
