Totally agree.. We want to have a Safari and Firefox one and are working on having that resolved quickly.

The code actually is written to be portable as a 'web extension' as both Safari and Firefox use the same general API.

I'll try to get some time and see if it works on Firefox. The biggest issue we have is testing. If something breaks on FF I want to know and we don't have a testing environment there.
