The final version of Firefox 4 was released on March 22nd. Windows users can download an installer directly from Firefox homepage and just run the installer. But for Ubuntu users it's not that simple. The best thing for them is using the package manager.
Most of the instructions for installation of Firefox 4 in Ubuntu point you to the Mozilla - Ubuntu daily build repository, which actually installs Minefield. Minefield is the unstable nightly build of Firefox. Of course those of us who are ardent Firefox fans have been using Minefield to get the latest betas and RCs and to feel the awe of Firefox 4. But now that the final version is out you can get rid of Minefield and upgrade the default Firefox installation in Ubuntu to version 4.
