Functions for Navigating in Firefox

2 posts in this topic

I saw the posting with some code for navigating in Internet Explorer so thought I would post the functions I have been using for navigating in Firefox (entering information, navigating tables, activating windows, etc). These were cleaned up as not to be specific to the web-pages I use them with, but I might have missed a couple of references or broken a couple of functions by renaming variables and eliminating window names/usernames/passwords.

I am sure there are better ways of doing many of these tasks but thought this might be useful for some, also remember I was (and still am) learning the language as I wrote these functions:

#include-once
