Display a warning dialog when Firefox(Thunderbird) is run from its disk image. I've heard a few annecdotes about people getting the firefox disk image and running from there, instead of dragging it to the applications folder. couldn't we display a warning dialog when Firefox(Thunderbird) is run from its disk image? see also bug #355884.

What's wrong with running from the disk image? It should work, and I frequently run apps from a DMG to see if I like them before copying them to my hard drive.

benjamin, I was thinking about the actions that would not work because you were running from a read only volume, such as software update.

seth: i have seen this type of feedback in user forums and hendrix as well. i think it is a bit confusing to users, and things going awry when they ran from the image.

Maybe we could at least make it possible to pref it off? I've learned to live with being EULAgized twenty times in ten minutes chasing regression windows, but I'd rather not make that EULAgized and readonly-warned forty times in fifteen minutes.

Phil, is there any reason you can't just copy it to the Desktop or something? See bug 320155#c16. The attachment of Quicksilver is rather nice. I think bsmedberg's comment is nice, but I don't really think we can be of two minds about this. "I want to run apps from the DMG" and "We want people to be installing things (i.e. not running them from the DMG)" are really not compatible. That said, it might not be a bad idea to replace Quit with Continue.

bug 516362 has lots more discussion about this.
