Can't refresh webpages since Mozilla is waiting for a script that doesn't answer
even if I click the box "don't ask again" it takes veeery long time to refresh the page since the script doesn't answer. I choose to stop loading the script but it doesn't help.

The Warning Unresponsive script - What it means and how to fix it article may help. One part of that article refers to problematic add-ons. If you have Personas Plus 1.6 use the procedure in the Troubleshoot extensions, themes and hardware acceleration issues to solve common Firefox problems article to disable or uninstall it, that add-on has been causing various problems.
Not related to your question, but you have old versions of Java and Flash installed and should upgrade them as they both contain known security holes.
You can get Java from http://java.com/
For Flash I prefer installing the latest version using the manual installer, for details see http://kb2.adobe.com/cps/191/tn_19166.html#main_ManualInstaller
