Packaging

To package the extension from source:

1. Navigate to the folder called /src.
2. Replace the contents of the file, manifest.json, with those from either manifest.firefox.json or manifest.chrome.json.
3. Zip/archive all the files and folders in the /src directory. Make sure the archiced file has the extension .zip. I recommend 7-Zip, but you can use any archiving tool of your choice.
4. (optional) Rename the generated .zip file.
5. Done.

TODO:

• Simplify the helper request functions by making a new function to do the chrome.tabs.query and sendMessage
• Make the tool also work on speedrun.com
