TabTools - Collect URLs of tabs tekijä Isaac Dendroff

An extension for Firefox that does 3 things (so far):
1. Open multiple URLs at a time (allows you to specify a list of URLS and opens multiple tabs for each URL)
2. See the number of windows and tabs open, and copy their URLs
3. Shows you every tab you have open in the current window, and allows you to switch to that tab just by clicking on its name inside the extension
