We have some good news and some bad news.
The bad news is that the release of Firefox 35 introduced a bug that prevents the FireRTC add-on from working properly.

The good news is that we have been working hard to release a web version and are completing our Chrome extension, so you will still be able to use the service. Once the bug has been addressed by Mozilla, or a work around can be found, we will release on Firefox.
Thanks for your patience. In an attempt to make it up to you, here is a picture of a kitten.
