Firebug in Firefox 3.1b2 and Beyond
I’ve been getting asked about this more and more recently, so I thought I should write something in an attempt to allay the confusion around this. Let me say this first:
Firebug 1.2.1 is not compatible with Firefox 3.1.
That bothers me, but not half-as-much as it probably bothers you, the person trying to debug some web on the latest, fastest, state-of-the-art Firefox (that kicks ass and is really cool and will make you more popular). But don’t fret! It won’t be this way for long. I’m hoping that today or tomorrow we’re going to release Firebug 1.3 on AMO!
Firebug 1.3 is not compatible with Firefox 3.1.
No, I’m not kidding. It sort of works, but there are a number of issues with it. It was never intended to work with Firefox 3.1 and as such, there are some known and probably many more unknown problems.
Let me say what I should have said at the start of this post: If you want to use Firebug with Firefox 3.1, you will need to use Firebug 1.4. Get the latest version from the releases directory and install it up. No compatibility override required. Don’t let the alpha version tag frighten you, it’s really quite decent.
Details about the different versions available on getfirebug.com’s releases page. Worth a read to see all the cool new features that have gone into these upcoming releases.
