Dave Yeo has refreshed (7/5/2014) his unofficial builds of SeaMonkey 2.14.11, Firefox 17.0.11, and Thunderbird 17.0.11, based on the Bitwise fork of the Gecko 17 "Extended Support Release" branch. Compared to the 17.0.5 Bitwise build of Firefox, they include several security fixes from the newer Gecko code, as well as a selection of important fixes back-ported from the Bitwise Gecko 24esr tree. These builds require libc065, and the fontconfig runtime. SeaMonkey is a continuation of the Mozilla Suite, while Firefox and Thunderbird are a stand-alone browser and mail/news client based on Mozilla code. See my Warpzilla Tips page for more information.
