I was doing some testing on an app that needed to display mouse events so instead of doing what I normally do I said its only quick debug so I'll set the window.status - No joy.....
Mozilla by default now disables access to WINDOW.STATUS
You have to enable it by going to : TOOLS->OPTIONS->CONTENT-> ADVANCED and enable "Change window status text"
Just a quick one incase you ever need to turn it on. This is a good thing to stop annoying sites but bad in general. There should be a wizard when installing Mozilla where you can specify whats turned off and not have to find things in the future.
This is one of my main gripes with Mozilla and Thunderbird. There doesnt seem to be any consistancy in where OPTIONS, SETTINGS or PREFERENCES are stored and their popup windows, dialogs, menus and tabs all hide settings in the most unpredictable places.
This is one of the reasons Windows is the de facto desktop operating system for normal users because they standardised the user interface. Even though Firefox is a great browser and Thunderbird is a great email application, you can see they were primerily developed on platforms other than Windows where there is no standard as far as settings, menu items etc should be placed.
