Firebug Releases
Four Different Firebug Release Streams
The stable release is on addons.mozilla.org
and is linked from the front page.
If you install from addons.mozilla.org, you will be updated only when a new stable release is available.
The latest release is on getfirebug.com (this page). If you install from this site you will be updated
incrementally to the latest usable versions: 1.2.0, 1.2.1b1, 1.2.1b2, 1.3b1, ....
If you want to get on a early release stream, install the alpha versions. These will update as we make progress,
1.3.0a1, 1.3.0a2, ..., 1.3.0b1,....
Finally Firebug Lite for non-Firefox browsers is distributed as files or bookmarklets.
