Every time I try to open it gives me the Unresponsive Script Warning, the script is 'Script: file:///C:/Program%20Files/Mozilla%20Firefox/components/nsExtensionManager.js:623'

If I press Stop Script, it comes back after 2 seconds, if I press Continue, it comes back later as well. Only when I check 'dont ask me again' and press continue does it not come back, but it takes up to 99% of my CPU.

It even comes up when I try to start FireFox in safe mode.

How do I get past the warning, and actually be able to use Firefox?

You need to uninstall or disable Personas Plus 1.6, it is causing similar problems for quite a few people.

Start Firefox in safe mode, you can then access the add-ons manager and uninstall or disable Persona Plus 1.6

For details on doing the above see the safe mode article. There are more details on uninstalling add-ons via safe mode in the Cannot remove an add-on (extension or theme) article. That article also shows how to manually remove add-ons.

I couldn't open Firefox in safe mode, as I said above. I gave up and just reinstalled Firefox 3.6.8. Now it works.
