NiftySplit (Port) by THFYM

Chrome's classic "NiftySplit" is now ported to that one other browser.

All credit goes to the extension's original author, Arno van den Brink. Seriously, this wouldn't be possible without him; I wrote very little actual code, and just tweaked a few things for Firefox compatibility. I can really take no credit for this.

From the Chrome store (and the original author):

Use NiftySplit to split [your browser] into two windows. Any link you click in the left window will load in the right window.

Is this useful? Yes!

You can now browse your favorite website and visit links without losing the main page. No need to use the Back button or open-and-close tabs all the time. This makes browsing websites like Reddit or Wikipedia a thing of pure joy.

Give it a try and let me know what you think!
