Well in Mozilla I found the tab scripts under the preferences option but it has only a few choices:
use js to move or resize windows, raise or lower windows, hide status bar, change status bar text, change images, disable or replace context menus. Obviously what I do in my site isn't in it
Looks like I'll be downloading firefox then.
Or am I missing something? I see mozilla does have a js debugger so I'm going to try that on my site as well.
