Make it possible to look for bugs across old nightly builds of Firefox using automated tools. For example, [http://db48x.net/regression-search/ regression-search] is a script that allows you to do binary searches across binaries, looking for the existence of a bug. This could be improved through the use of tools like [http://services.alphaworks.ibm.com/coscripter/browse/about co-scripter]. Ideally the user could look for bugs in automated ways, without having to download and install tons of browser versions.
