On its Mozilla Add-ons page, Acebug does not have 'coffeescript' as a tag. I think it should.
When I heard of the release of CoffeeConsole for Chrome a few days ago, I searched on Google for a similar extension for Firefox. I clicked a link to a search page for the tag coffeescript on Mozilla Add-ons. That search brings up only the add-on xqjs, which made me think there was no Firebug-integrated CoffeeScript console currently existing. If Acebug had been tagged 'coffeescript', I would have found Acebug then. (I found Acebug now only because someone replied to a comment I wrote in which I wished for such an extension.)
i completely forgot about the tags. added coffee and coffeescript now
i saw post about CoffeeConsole early when there were only a few comments, thought i'll look again later to see if someone mentions firefox or acebug, but forgot:)
if you have any suggestions on making acebug better or anything is unclear in documentation, feel free to create issues here
thank you very much
