Doesn't prettify, just colors Rated 3 out of 5 stars
On Firefox 3.1 it wont format the JSON at all, it just colors it. Leaving it all on one line as usual.
Seems a little odd since everyone else seems to think it does format the JSON.
UPDATE: Hey, Squeegy, thanks again for the feedback. The 0.9.3 version I just committed should fix this in Firefox 3.1 and 3.2.
I've had conflicting reports on the 3.1 behavior, but this is enough to tell me there's a problem. I suspect that the parser for 3.1 isn't handling indentation properly, and the extension defers to the built-in parser for 3.1. I put that in there before I was sure how 3.1 would behave, and now that's bitten me in the bum.
I hope to commit a fix tomorrow. Please let me know if that doesn't do the trick.
