Comment 30 for bug 216699

I am still unable to reproduce this bug. Can you please run the following command and visit those sites in safe-mode.
firefox --safe-mode
The pages open fine there is a slight lag on http://www.kohanaphp.com/ but by no means is it a "hang". Since everyone elses problem went away except yours im thinking its either an extensions or your profile.
If safe-mode still sees this issue try running the following command
firefox -ProfileManager
When running profile manager do not name the new one the same as the old one, also dont remove any profile just add one with a different name or your old one will be removed.
