incompatibility issue Rated 4 out of 5 stars

"This add-on is incompatible with Firefox 26 and greater. Please use the App Manager with the new Simulator add-ons." Why ??

This review is for a previous version of the add-on (4.0.1). 

Changes in the Developer Tools API made it hard to continue to support the addon with newer versions of Firefox. Fortunately, the App Manager is a fantastic new tool for testing apps, and there are new Simulator addons you can use with it. See this documentation for more details!

Excelente sistema!
Atualmente uso o NetBeans 7.4 (PHP/CSS3/HTML5) para desenvolver, mas, vocês tem intenção de lançar uma ferramenta própia de desenvolvimento para Firefox OS?

default apps Rated 3 out of 5 stars

Looks OK, but would be a lot easier to get going if it came with at least some default demo apps; or maybe those needing most work, review?

Works nicely! Rated 5 out of 5 stars

Works smoothly.
The only thing I'm missing is mp3 support, it's a little difficult to test media apps without it, any plans to implement that soon?
