User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:31.0) Gecko/20100101 Firefox/31.0 Build ID: 20140816133558 Steps to reproduce: Please consider installing this AppData file we wrote: https://raw.githubusercontent.com/hughsie/fedora-appstream/master/appdata-extra/desktop/firefox.appdata.xml This is used in GNOME and KDE software installers to add the application description and some screenshots. We'd love to showcase more applications, but without the extra data file we can't. The AppData file needs to be installed to /usr/share/appdata/ on Linux and the basename needs to match the .desktop basename. It would also be great if you could integrate the file with your translation system (e.g. intltool) to make the descriptions translated. See http://people.freedesktop.org/~hughsient/appdata/ for more details; thanks! Richard Actual results: Firefox looks beautiful in the software center. Expected results: Firefox should look awesome.

Mozilla.org doesn't provide an installer for linux, only a .tar.bz2 file is offered example: ftp://ftp.mozilla.org/pub/firefox/releases/32.0.2/linux-x86_64/en-US/ Packages are created by the distributions and you have to ask Fedora, Ubuntu, debian ... to include it in their packages

I think it is a time to reconsider this. The AppData is now a distro-agnostic format under the umbrella of FreeDesktop.org which is currently used in all major distributions (Fedora, Debian, Ubuntu, openSUSE, RHEL, Arch,...) to create rich app profile in app catalogs (e.g. GNOME Software or KDE Muon): https://www.freedesktop.org/software/appstream/docs/ The format is widely used among Linux distributions and an app profile is part of the app branding, so it definitely makes sense to maintain this metadata upstream. This way, Mozilla has control over the description and screenshots and can ensure the same messaging across Linux distributions. The metadata has been shipped upstream for example by LibreOffice and now it's being accepted by Chromium as well. The metadata can also be translated to provide the best experience to users who don't speak English: https://www.freedesktop.org/software/appstream/docs/sect-Quickstart-Translation.html To do that, we would need to put the right appdata.xml into browser/branding/official/ directory (or also browser/branding/aurora in case someone would like to ship Developer Edition). I would leave it up to package maintainer how to obtain it from tarball, or we could install it to the /usr/share/metainfo/%{id}.appdata.xml as mentioned in the specification there: https://www.freedesktop.org/software/appstream/docs/chap-Quickstart.html#sect-Quickstart-DesktopApps I think the shell integration is the better component. This enhancement could be also discussed or even moved to the marketing team if relevant.

Do you have a new version of this file? The old one is a 404.

Sure, I spent a bit of time updating it to the latest specification level this morning. https://people.freedesktop.org/~hughsient/temp/firefox.appdata.xml Thanks, and I'm happy to answer any questions. Richard.

404 again. Sorry, can you provide the file again and this time I will attach?

I've re-uploaded it to https://people.freedesktop.org/~hughsient/temp/firefox.appdata.xml -- it's missing lots of important information. `appstream-util validate-relax` can be used to validate the document. It also needs wiring in to the translation system somehow. Thanks.
