Firefox’s four release channels explained
Mozilla’s got a handy new graphic that clearly shows what you can expect from each build — Stable, Beta, Aurora, and Nightly. To seasoned veterans of the web it’s a no brainer, but the image and a little explanation is handy for more casual users who want to know if the grass is greener on the other side.
As you move from left to right on the list, the Firefox builds become more cutting edge and less polished. The Nightly build is where full-on experimentation happens. Features sometimes appear one day and disappear the next, crashing is to be expected, and not all of your favorite Firefox add-ons are going to work.
Move over to Aurora, and you’ll be treated to the first taste of upcoming Firefox features in a (relatively) stable build. While you’ll get to play with these features early, there’s no guarantee they’ll ever make it to the Beta or Stable channels.
