Can't open Firefox OS Simulator with Australis UI
I am testing Australis on nightly. I want to use Firefox OS Simulator. For that I added 'Developers' into 'Customize and control nightly' block. I am able to see Firefox OS Simulator here, but can not open it. To do so I have to press F10 and go to Tools > Web Developers.
Your Bug report has been added to the master Tracking Bug for Australis regressions since landing on Nightly.
The developers will deal with your Bug over the next couple of months as Nightly 28.0 makes it through the Nightly, Aurora, and Beta development channels.
