Safari Browser not working.

I called Apple tech support and spoke to David, who was very helpful. Removing Symantec products fixed it for me.

First thing we did was a 'Safe Boot'. Turned the computer off, and as it restarted, pressed the Shift key. That starts just the core of the Operating System without any add-ons. Safari worked just fine. So the problem was narrowed down to third-party installed applications.

Things we then tried:

1. Removing Computer > Library > Caches directory and <User Home> > Library > Caches directory. (The Library folder is hidden by default. In a new Finder window, I clicked 'Go' and pressed the Options key to see the Library directory.)
2. We also cleaned out Safari data.
3. Checked to see no unnecessary plug-ins were installed in the Library > Internet Plug-ins directories.
4. Checked out the LaunchAgents directory in the Library directories to make sure nothing "funky" was kept there.
5. Restarted.

None of it solved the problem.

So finally, he asked me to try uninstalling Symantec products. I went into Applications > Symantec Solutions folder and started the Uninstall program. Restarted computer. *Browser back to normal!* Apparently, some Symantec firewall setting may have become corrupted, preventing the browser from going to the internet.

I have since reinstalled Symantec, and so far things seem fine.

I had to do this after an upgrade to 10.11 public beta same error had to remove norton.

You should not have reinstalled Symantic. Norton simply does not blend with Macs. I really feel you should remove it ... and If Ian of Mumbai has it, I suggest he does the same thing.
