Hello, see if Java or Flash is disabled...
Mac OS X 10.5, Product Security, Safari 5.1 (Mac OS X 10.6), Safari 5.1 (OS X Lion)
Safari 5.1.7 for OS X Lion, Safari 5.1.7 for OS X Snow Leopard, and Leopard Security Update 2012-003 disable out-of-date versions of Adobe Flash Player.
Out-of-date versions of Adobe Flash Player do not include the latest security updates and will be disabled to help keep your Mac secure. If Safari 5.1.7 or Leopard Security Update 2012-003 detects an out-of-date version of Flash Player on your system, you will see a dialog informing you that Flash Player has been disabled. The dialog provides the option to go directly to Adobe's website, where you can download and install an updated version of Flash Player.
If you need to re-enable an out-of-date version of Flash Player, you can do the following:
1. Navigate to the /Library/Internet Plug-Ins (Disabled) folder.
2. Drag "Flash Player.plugin" into /Library/Internet Plug-Ins.
3. If the browser is running, quit and restart it.
See in each Browser which version of Flash it thinks it has...
Then Test Adobe Shockwave & Flash Players...
:Thanks to Andrew over in another thread, he posted the solution to how to fix my problem. I restored a backup of a previous Hosts file and it fixed the problem. But my question now is, how did it get mofified and/or corrupted? Thanks Andrew:Re: Unable to access Facebook from ANY browser on my Mac (suddenly)
I had the same problem, and I just fixed it. See this thread-https://discussions.apple.com/thread/4612888?start=0&tstart=0
