I’m writing you today to solicit for assistance over the weekend. If you are an active Facebook user, please download the latest Beta or the latest Firefox 18 Candidate and use Facebook as heavily as you can this weekend. We are looking for any issues with stability (ie. crashes) on Facebook. We need your feedback before the end of business on Monday, February 4th (5pm Pacific).
If you encounter a crash, please email us and provide a link to your crash reports (you can get crash reports from the about:crashes page in Firefox).
