Yes, basically all browsers that support Mozilla Midas API which, for now are, Mozilla 1.3 or greater. Note that Midas is *NOT* part of standard Gecko, so Camino won't do it.
Hmmm, under Mozilla 1.3 (Linux) I'm getting this error:
I'm sorry, but Linotype doesn't work on this browser:
Error: uncaught exception: [Exception... "Component returned failure code: 0xbfffb9b8 [nsIDOMNSHTMLDocument.execCommand]" nsresult: "0xbfffb9b8 (<unknown>)" location: "JS frame :: http://127.0.0.1:8888/samples/linotype/scripts/editor.js :: start :: line 44" data: no]
What might the problem be?
