> clicking a link to a .m file triggers a download Firefox can be convinced to simply show you any resource that you know is some flavor of plain text if you open it in View Source mode, i.e. by constructing a view-source: URI out of the original URL and accessing it that way. So to bypass the download nag screen for Anchor.m, you'd access it as <view-source:https://www.w3.org/History/1991-WWW-NeXT/Implementation/Anchor.m https://www.w3.org/History/1991-WWW-NeXT/Implementation/Anch...> instead. This even works on Firefox for Android, but not Chrome. (Of course you don't need to construct these by hand most of the time; if you're on a page linking to a bunch of files that otherwise prompt you to download them, like the Apache directory listing in this case, you just view the source of the directory listing page and click the links in the href attribute values there.) This is pretty useful in multiple circumstances—which of course means that someone at Mozilla Corp will remove it from Firefox or find some other way to stop you from doing this any day now.
