Mac OS X

  • Make significant progress on Firefox 3 stability. Quantifying is difficult because of Socorro problems at the moment.

  • Fix all Mac OS X bugs blocking the Firefox 3 major update. This includes bug 357670 and bug 428405.
    • Major update shipped. Fixes for both bugs listed here have been landed for Firefox 3.0.2.
  • Fix all Mac OS X platform bugs blocking a Gecko 1.9-based Camino release. This includes bug 433719.
    • Bug 433719 fixed on trunk, waiting for approval. We don't know of any other trunk platform blockers for Camino.
  • Be prepared to ship Cocoa event model for NPAPI in Firefox 3.1 (code in the tree). This is bug 435041.
    • Due to unforeseen difficulties this has been put off until after Firefox 3.1 and instead we have been working on other plugin-related tasks.
  • Make a decision about how we'll support Java in Firefox 3.1 for Mac OS X and complete any coding required to support our decision.
