What's this? This is a build of Firefox 7.0 optimized for running on Windows 98 and higher using KernelEx 4.5.1. Why not use the regular build? Mozilla's official version, or rather their integrated SQLite3, triggers a bug in KernelEx when using Write-Ahead Logging, which causes massive slowdowns, rendering Firefox useless. This version features a workaround for that problem. It just disables use of WAL. This bug was discovered and reported by aceman, see http://sourceforge.net/tracker/?func=det
