Cannot preview changes in Firefox 3.6.3

[Dal123]

I designed my website and trying to put a few changes on it, now I can't preview my changes from Dreamweaver.
There is a way around it as I quit Firefox; so unopen. Then through Dreamweaver 'preview in browser', and it works. Is this a bug or something like that?

Why not just have the page loaded in the browser and refresh it when you make changes? That's pretty much what Preview does....isn't it?

No buddy, you need to export from Dreamweaver as the changes are made there as it's on a local disk I would've thought.
I notice when going from Dreamweaver I get 'there is already another version of this browser running, please close the other browser before previewing'. But when you close window it does not work, you need to quit the application; don't understand why they would change this on an update .
