After mulling this over for a bit, I'm of the opinion that functionality specific to `/firefox/new/` should *not* be included in `global.js`. I realize this may result in more/repeated code, but I think it's worth it to keep `global.js` simpler and more focused. Adding one-off/page-specific code here will make updating/debugging this already complex function more costly.

As long as the amount of code repetition is minimal, I'd vote for keeping specific `/firefox/new` functionality tied to that page's `.js` file.
