Updates are available for nightly builds of Firefox & Thunderbird | Updates are available for nightly builds of Firefox & Thunderbird. Keeping this system running requires the coordination of tinderbox configuration, partial update generation, and the AUS server that provides update information the client applications. This document describes how that all works, to the extent that publicly available information allows. Hopefully the build crew and Mike Morgan can fill out the details to make this page more complete. | ||
Scope: Currently, updates are setup for the en-US locale on the branches for 1.5.x.y and 2.0, and on the trunk. The three Tier-1 platforms of Windows, Linux and Macintosh (ppc) are supported for the two main toolkit apps, Firefox & Thunderbird. | |||

The situation with the Mozilla1.8.0 branch needs fixing up (partly [https://bugzilla.mozilla.org/show_bug.cgi?id=328497 Bug 328497]), an $update_version of "1.5.x.y" would be flexible. | ||
