Test== '''1:''' Research ==:At first I had decided to build Firefox using Visual Studio 2005 on Windows XP. No knowing where to start I did what I usually do when I don’t have a clue about something. I googled it. Using the following search query “build Firefox using visual studio” in google I was directed to [http://cs.senecac.on.ca/~david.humphrey/writing/firefox-win32-build.html]. :I followed the instructions on that page up to the point where the buildsetup.bat needed to be executed. It did not work. I was unable to execute the script. I knew this because it wasn’t setting up the correct environmental variables for CVS to work properly. After an hour of struggle with this problem I decided to give up on Windows and decided to try my luck with OS X.:I searched google with the following query “mac osx build firefox” and this page [http://developer.mozilla.org/en/docs/Build_Documentation] was returned as one of the search results.
