I’m writing to let you know that this Friday, September 4th, we’ll be hosting the Firefox 41.0 Beta 7 Testday. The main focus of this event is going to be set on Flash on 64-bit Firefox builds and plug-ins testing. Detailed participation instructions are available in this etherpad.

No previous testing experience is required so feel free to join us on the #qa IRC channel and our moderators will make sure you’ve got everything you need to get started.

Hope to see you all on Friday! Let’s make Firefox better together!
