Grandfather Fox by Wesley Branton

When you're browsing on Firefox, it's easy to lose track of time. The Grandfather Fox add-on turns your browser into a classic grandfather clock that will chime each hour. It promotes time awareness, while also giving your home office a bit of class.

The add-on currently features a variety of audio packs, including:

• Traditional grandfather clock
• Cuckoo clock
• Single beep
• Multiple progressive beeps
• Clock tower

You can also provide your own custom chimes.
