The one that works Rated 5 out of 5 stars
There are some other URL shorteners for Firefox that don't work anymore. This one still works and works like a charm.Glad to see that it integrates well with goo.gl stats.
Two suggestions —
1. Icons beside context menu entries (for easy identification).
2. Optional cascaded context menu (so that the main menu remains clutter free).
Keep up the good work.
