The Simulator is not working in the beta 20 version build- 5 of firefox. When i start the simulator it pops up new window and it automatically stops.
Dont know why.
I am using windows 7 and x86 processor
Thanks for reporting the problem, and sorry to hear the Simulator isn't working for you! Could you try installing the latest preview build for Windows to see if it still has the problem?
Closing this due to lack of needed info. But please do reopen if you can provide that info!
