Changing firebug’s font size
One problem I’ve had a couple of times when using Firebug to show things during code demos is I haven’t been able to make the font big enough for people at the back to read it.
I found the solution at stack overflow:
1. Open firebug in new window
2. Go to the view->text size menu
3. Close the window and it should be the right size when you reopen it.
