Time to explore all of your favorite Personas, and make sure they mesh well with the latest Firefox beta (or nightly)! Firefox 4 has had some UI changes such as Tabs on Top, the new Addons Manager, etc.
We will have moderators and community members available to help test and answer questions. Come by the IRC Chat (channel #testday on irc://irc.mozilla.org) to see what other people are up to, and to participate. We’ll start Friday morning and continue throughout the day [PST]. The Test Day will run from 9 AM – 5 PM PST.
http://etherpad.mozilla.com:9000/PersonasTestDay will be the document we will use to frame our testing. In fact, feel free to add your ideas about what you think we should explore during the Test Day.
