Running Safari 5.1.9 on a MacBookPro with OS X 10.6.8 and no websites will open. Firefox works fine on same machine. Any suggestions? I've had this computer over 2 years and have never encountered this problem.
MacBook Pro, Mac OS X (10.6.8)
Open System Preferences > Network > Advanced > Proxies
Deselect any checked boxes on the left then click OK. Quit and relaunch Safari to test.
If it's not a proxy issue, try troubleshooting extensions and third party plug-ins.
From your Safari menu bar click Safari > Preferences then select the Extensions tab. Turn that off if there are any installed. Quit and relaunch Safari to test. If that helped, turn extensions back on then uninstall one a time to test.
If it's not an extensions issue, try troubleshooting third party plug-ins.
Back to Safari > Preferences. This time select the Security tab. Deselect: Allow all other plug-ins. Quit and relaunch Safari to test.
If that made a difference, instructions for troubleshooting plugins here.
If nothing above helped, try this DNS.
Open System Preferences > Network > Advanced > DNS
Click + and type:
208.67.222.222
Click + again and do the same.
208.67.220.220
Click OK.
Quit and relaunch Safari to test.
