I’m writing to let you know that Friday, August 21st, we’ll be hosting the Firefox 41.0 Beta 3 Testday. The main focus of this event is going to be set on Firefox Hello Text Chat and Add-ons Signing. 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!
