In order to ensure the new browser survives in it’s next mode, the Firefox 3 timeline has been completely scrapped and a new one has been put in place.

In a note to the Mozilla development planning group Mike Schroepfer, vice president of engineering, said:

We are driven by quality, not time. We want to Firefox 3 to be something that we are all proud of. This means features that delight users and the same or higher quality than previous releases. “Quality” includes performance (Tp/Ts/TDHTML/etc), footprint, web compatibility, regressions, and general fit and finish. Having said that, we want to move the web forward and are in a competitive market. So we should converge on a release as fast as possible.
