How do I change the 'weather' button to give Australian temp in celsius, and pressure in kPa?
There is a weather button in one of the toolbars. It gives readings in the US units. How do I change it to the mksa (or European) system. i.e. Celsius not Fahrenheit, etc.

That's not a standard feature in Firefox. It was probably added by an extension you installed. Visit the https://Addons.Mozilla.org page where you downloaded that extension from, and look at the More about this add-on... or visit the developer's website for instructions for using and configuring that extension.
