Currently (0.9.9) Moz does not explicitely associate icons to file types that it handles. The result is that the shell assigns the default Moz binary icon. The file type association groups - a) images, eg .png, b) "protocol", eg .html should have unique icons (and ones other than that used for the binary). For example, - the IE binary has the stylized 'e' icon. - the IE "protocol" file types icon is a "sheet of paper" with a mini 'e'. - the IE image file types icon is a "sheet of paper" with a picture frame in it - see .JFIF and .JFE which are incidentally also jpeg file types, but are not reassigned to Moz. The "sheet of paper" metaphor to describe a file is actually quite good - every Windows/Mac user knows what a 'folder' looks like, and everyone knows what a folder contains. (And no, folders do not contain dinosaur heads or inkblots that are supposed to be seamonkeys :)

this might not be the right bug, but please don't reopen, it isn't worth it, the bug you want is in that tree and the bug i've picked has the spec (although it may be inaccessible) *** This bug has been marked as a duplicate of 73712 ***
