We have also made a decision that includes following strategy:
- Release final 1.6.0 as soon as possible (pushed on AMO in couple of weeks).
- Set the compatibility on 1.6.0 to FF 3.6 (because we cannot test on FF 4.0).
- Ship 1.7b1 in six weeks as the Firefox 4.0 solution, in sync with Firefox 4.0 approaching its final release.
Please post feedback in the newsgroup.
