If I enable e10s manually on my Windows 8 touch-screen machine, every time Firefox starts it will ask me if I want to turn it off. If I don't actively say no, e10s will be off the next time Firefox restarts. There doesn't appear to be any way to disable this behaviour. I seem to also be experiencing situations where it just turns itself off without any interaction, but I assume this must be happening in situations I manage to accidentally dismiss this dialog without telling it not to disable e10s. I like e10s and would like to help test. Oddly, touch-screen input with e10s appears to work fine, so I don't know why it's triggering this warning. I expect we're missing out on a reasonable number of testers because of this.
Likely bug 1108607?
