Facebook error message and locking my computer

[o803oVaDeR]

I have not made any changes that I am aware of, but when I try to get on face book I get this message:

Exception... "Security Manager vetoed action" nsresult: "0x80570027 (NS_ERROR_XPC_SECURITY_MANAGER_VETO)" location: "JS frame :: chrome://fctoolbara288034635bb45bb9190eedb49c132c5/content/fctoolbar.js :: NavigateComplete :: line 12" data: no]+

I can close it and log on normally, but I then get the Not Respnding message and my computer locks up. Facebook seems to be the only web site I am having problems with. Any ideas?

Sounds like a virus.

If you're running any userscripts or add-ons in the browser, disable them & try again.

If nothing, try disabling any firewalls/antiviruses & try again

If nothing, try using a browser besides chrome, maybe Firefox 5.0 or the latest Opera.

If that doesn't work, idk what to tell you. A lot of people have had this problem with shitty Facebook the past month, so it might be something on their end conflicting that needs to be fixed.
