INSTRUCTIONS ON HOW TO INSTALL IN WINDOWS BELOW

So far this is working fine with Windows 8.1 - I will report back if I have any issues in 7 or 10 when I get around to installing it on my other systems.

For those not understanding WHY this new setup is required, Firefox has completely changed how extensions will work moving forward. Long story short, they took away the deep functionality which pretty much all developers relied on. Trust me, no one is happy about it and the majority of devs are publicly jumping ship.

However, I'm not sure of the issue from reviewers about installing Python for this extension to work, since all it does is expand a few language extensions in the background on your computer. Python has been around since 1991 and trustworthy. A standard user will never see a difference in any normal day to day operations.

For those who do not understand how to install in Windows:
1. Install Python (Download from link, run file, and then follow install screens)
2. Download the linked .py file and then move it to a special folder or the root of your C:/ drive (I put mine under the python install folder/Lib)
3. Open a Windows Command prompt (Type command or cmd into Start Menu search and select the cmd.exe)
4. Navigate inside the command prompt to the folder where you put the file in #2 (i.e. "cd c:\path_of_file_folder")
5. Run the command given in instructions: "open_with_windows.py install" (You must be in the same folder as the file)
6. Click Test in the extension info screen inside of Firefox. It will tell you immediately if it worked and you can begin finding/adding external programs to launch
