Since new versions of Mozilla are complied nightly, a newer version is almost always available in mozilla.org's latest directory. getmoz is a sh (Bourne Shell) script that was written to automate the downloading and installing of the latest Mozilla build while backing up the current build. This is all done without any user intervention, and should allow for more quality assurance of Mozilla, as well as providing an effortless way for end users to check out the latest versions of Mozilla.

As for the stability of the latest Mozilla builds, we recommend monitoring comments on, and contributing your own comments to, Mozilla based newsgroups or sites like Mozillazine and Mozilla News. If you think you have found a bug with Mozilla, you are encouraged to search for it in Bugzilla and then report it if you cannot find it. When reporting a bug, be sure to follow the guidelines spelled out on the Mozilla QA page titled Bug Writing Guidelines. And remember, to quote Eric S. Raymond, "Given enough eyeballs, all bugs are shallow."
