Hello. Sometime when saving a jpeg image from firefox (if the file has a name such as "blahblah.jpg:large"), firefox adds a ".jpe" extension. This is a bug and it should instead add .jpg or .jpeg.

This can be fixed by removing jpe from the /etc/mime.types or moving to the last place. This problem could be solved in arch linux by either editing the mime-types file or importing the fedora one instead of the gentoo one.

I can confirm that I experience this bug (images from Twitter are one example of jpegs-not-ending-with-a-proper-extension), and that moving jpe to the end of the line fixes the issue (seemingly firefox assumes the first thing in the list is the canonical one).

Potentially of note: if this fix were applied it would be the only instance in the file where the extensions are not in alphabetical order[1]. Perhaps the true bug is with firefox assuming that the first is the best?

[1]: cat /etc/mime.types | grep -Po '(?<=\t)[^\t].*$' | perl -pe '$_ = join(" ", sort(split(/ /)))' | md5sum
== cat /etc/mime.types | grep -Po '(?<=\t)[^\t].*$' | md5sum

I'm considering replacing Gentoo mime-types with Fedora mailcap.
