We will be building a Firefox Beta update tomorrow (2011-06-03) morning EDT. We will be taking the latest code in releases/mozilla-beta and creating updates for our beta audience to test. Both mobile and desktop will be building at this time.
*This means patches approved to land on mozilla-beta[1] should come in today, or they will have wait another week for the next refresh.*
We intend to have the update on the beta channel the following week, most likely Monday or Tuesday afternoon PDT.
Thanks,
Christian
