Safari doesn't load after upgrade to 5.1

Question

Following the recent OS update to 10.6.8 and the Safari upgrade to 5.1, Safari will not load any internet page (it doesn't freeze. This only happens with my user and it works perfectly for another user. I removed my plugins, cookie files, safari.plist, removed and reinstalled safari but nothing helped.
Any suggestions?

Just your user account? That's the good part, at least it's not a system wide issue.
From the Safari menu bar click Safari / Preferences then select the Security tab.
Deselect:  Enable plug ins
Quit then relaunch Safari. If pages load then it's a third party add preventing pages from loading. This can happen when an add on was compatibility with the prior version of Safari but not 5.1.
I see your check plugins but they are easy to miss.
Check these folders:
Manually uninstall third-party add-ons
If the software doesn't have an uninstall feature, quit Safari and try manually removing the third-party add-on files. These files are usually installed in one or more of the following locations:
/Library/Internet Plug-Ins/
/Library/Input Methods/
/Library/InputManagers/
/Library/ScriptingAdditions
~/Library/Internet Plug-Ins/
~/Library/Input Methods/
~/Library/InputManagers/
~/Library/ScriptingAdditions
The first four locations listed are in the root-level Library on your hard disk, not the user-level Library in your Home folder.
The tilde (~) represents your Home folder.
You should also check Extensions. Back to the Safari menu bar click Safari / Preferences then select the Extensions tab. If you have any installed, turn that off, quit then relaunch Safari to test.
