Bug 1369399 - Re-enable e10s for DevEdition. r=Felipe I thought of fixing this in the e10srollout addon because DevEdition is now built off of Beta, but it would only serve to complicate the addon even more and expose us to more risk every time we touch it. Also, DevEdition stayed on the Aurora update channel and who knows if we're going to change that in the future. Special casing DevEdition (via AppConstants) is possible, but it was going to get messy pretty quickly. This is probably the most straightforward way to make this all work.
