I'm running the latest Next snapshot.\n\n\nWhen I start it, the Firefox window sits there, and no matter what I do,\nbrowse mode doesn't start. Alt+tab doesn't do anything either.\n\n\nSometimes, I've had to restart NVDA several times before all works\nright. I run Firefox Nightly. I\"m running Windows 8.1 64 bit.\n\n\n\n------------------------------------------------------------------------\n\nOn 9/15/2016 10:02 PM, James Teh wrote:\n>\n> This has been confirmed by several users.
