I cano confirm this on build: Mozilla/5.0 (X11; U; Linux armv71; Nokia N900; en-US; rv:1.9.3a5pre) Gecko/20100527 Namoroka/3.7a5pre Fennec/2.0a1pre
Must be something in the platform. We already try to disable the "Open" button is the file does not have a handler: http://mxr.mozilla.org/mobile-browser/source/chrome/content/browser.js#2714

I'm seeing mar files on my Linux build with an open option that does nothing.
Yeah, its still true. I went to my n900 and downloaded a .dmg file and tried to open it.

So, 1. We open files using nsiLocalFile.Launch. That calls OS level stuff, basically it's the same as doubleclicking the file on windows, running |gnome-open| on GNOME, etc. 2. There is no feedback from Launch() about whether it succeeded or not. Optimally we would like something like 'CanLaunch', I guess, on that interface. 3. We can try to disable the 'Open' button if the file doesn't match any familiar mimetype, but the danger is that the file might be launchable despite not having a familiar mimetype - Launch may succeed where mimetype discovery fails. -- The best solution for now might be something in Maemo or Qt, for example having the OS launcher display a visual warning if a file is not openable. On a related note it seems this bug doesn't appear in Android only because when you open a file with no launcher, it tries to launch it in the native browser - so at least something happens and the user gets feedback.
Patch tests the mimetype, if none exists, then the |Open| button is disabled. The risk still exists, as mentioned in the previous comment, that Launch() and the mimetype do not agree between them.

Comment on attachment 490768 [details] [diff] [review] patch Nice catch. We are at least better off than before. If we run into situations where the mimeType and Launch() don't agree, we can look at implementing something additional.
