I tried to reproduce this issue but it works fine for me. The file dialog automatically adds ".jpeg" to the file name.

Please test again to see if it is reproducible for you, with latest Nightly version (you can download it from https://nightly.mozilla.org/) and also with a new profile. Steps to create a new profile can be found at https://support.mozilla.org/en-US/kb/profile-manager-create-and-remove-firefox-profiles.

Thank you.

Strange, I can still reproduce it with Firefox 46 and a clean profile.

Please try again in safe mode. If it's still reproducible, please give some additional information on how to reproduce it. Also a short video would help.

Safe mode does not change anything. However I could not reproduce it on Windows.

Thank you for your effort.
I tried the same on Ubuntu 12.04 and Ubuntu 14.04 but still ".jpeg" is added to the file name. I also attached a screenshot where you can see the file dialog automatically adds ".jpeg" to the file name.
Did you used a different OS?

WFM on Win10 Fx43 with .jpg & Lubuntu 14.04 LTS Fx42 with .jpeg.

I am using Arch Linux. Changing the locale has no effect. It looks like .jpeg gets truncated to .jpe for me. But why is it .jpg on Windows?

Comment 10

[Thomas Wisniewski]

Odd. This reproduces for me on a (rather stock) Gentoo Linux setup (".jpe" added to the name), but a stock Ubuntu 16.07 LiveCD VM adds ".jpeg" to the extension instead (ui.allow_platform_file_picker didn't change things in either case).

Comment 11

[Thomas Wisniewski]

Ah, it's because this is in my Gentoo /etc/mime.types:
  image/jpeg     jpe jpeg jpg

Whereas in Ubuntu I have:
  image/jpeg     jpeg jpg jpe

Given that Chrome adds ".jpg" one way or the other, I think Firefox could stand to be more reasonable and at least choose one of the more common extensions, instead of just picking the first entry in that list.

Good catch, this is indeed the explanation. Arch Linux uses the mime.types file from Gentoo, see [1].
And there is even an open bug report [2] for this issue. But nothing changed since 2013...
