Safari in Lion has stopped working.

Question

Safari in Lion has stopped working.  All my peers that have lion have been having this problem, and those that still have Snow Leopard have no issues with their Safari. The loading animation only gets to about as far as "http://" and just hangs there. It says it's connected to the internet (i've tried with both wi-fi and ethernet). I have no idea what happened, as it had been working for a solid month before this.
I'm sadly writing this message from the firefox browser .
In the past to get it to start working again (for a short period of time), i would:
Emtpy Cache in Safari
Reset Safari
Remove my Wi-Fi remembered internets
Delete Wi-fi
Reboot the computer
Re-add Wifi
Reconnect to the internet
it would still hang for a bit, but eventually it would load a page.
If anyone has any advise, it's much appreciated.

Answer 1

Third-party system modifications are a common cause of usability problems. By a “system modification,” I mean software that affects the operation of other software -- potentially for the worse. The following procedure will help identify which such modifications you've installed. Don’t be alarmed by the complexity of these instructions -- they’re easy to carry out and won’t change anything on your Mac.
These steps are to be taken while booted in “normal” mode, not in safe mode. If you’re now running in safe mode, reboot as usual before continuing.
Below are four lines of text in monospaced type, which are actually shell commands -- little programs. They’re harmless, but they must be used exactly as given in order to work. Some of the lines will probably wrap in your browser, but each one is really just a single long line, all of which must be selected. You can accomplish this easily by triple-clicking anywhere in the line. The whole line will highlight, and you can then either copy or drag it. The headings “Step 1” and so on are not part of the commands.
Step 1
Launch the Terminal application, copy or drag -- do not type -- the line below into the window, and press return:
kextstat -kl | awk ' !/apple/ { print $6 $7 } '
Post the lines of output (if any) that appear below what you just entered (the text, please, not a screenshot.)
Step 2
Repeat with this line:
sudo launchctl list | sed 1d | awk ' !/0x|apple|com\.vix|edu\.|org\./ { print $3 } '
This time, you'll be prompted for your login password, which won't be displayed when you type it. You may get a one-time warning not to screw up. You don't need to post the warning.
Step 3
launchctl list | sed 1d | awk ' !/0x|apple|edu\.|org\./ { print $3 } '
Step 4
ls -1A {,/}Library/{Ad,Compon,Ex,Fram,In,La,Mail/Bu,P*P,Priv,Qu,Scripti,Sta}* 2> /dev/null
Important: If you synchronize with a MobileMe account, your me.com email address will appear in the output of the above command. Change it to something like “[email protected]” before posting.
Remember, this is all drag-and-drop or copy-and-paste, whichever you prefer -- no typing, except your password.
You can then quit Terminal.
