I remember similar problems during some experiments I was attempting a while
back.
Another option is to simply reopen the browser class you want to extend, and
start adding your own methods:
class FireWatir::Firefox
def your_custom_method
....
Needless to say, if the Watir::IE / FireWatir::Firefox class and module
structure ever changes, this code will break. How badly depends on how
extensive the future changes are, I guess. :)
But for what you are trying to do it might work.
Also, one must be careful not to step on any methods that already exist.
You can extend existing methods without much trouble, but the code gets a
little more complicated (especially when extending class methods instead of
instance methods). Some searches for info on Ruby "alias chaining" might
help if you want to extend existing methods.
Thanks
