This question is in two parts:
1) I want to open url's in firefox, at this point, the assumption can be made that firefox is installed (since it's going to be used on my system), and
2) once I have the tabs open, I want to read back the page source(s) into a multi-line text box.
Let's assume (for the sake of argument) that at this point I want to open two tabs and read back the source from the firefox browser. The key point is that I need to be able to get the source for all open tabs
