Change menu name from "Firefox Web Browser" to "Firefox"

[Vincent Chernin]

Ubuntu 20.10 (and downstream distros using Ubuntu's firefox package).

Package version: 84.0+build3-0ubuntu0.20.10.1

Firefox on Ubuntu uses "Firefox Web Browser" as its name in the GNOME menu (shown in top left when Firefox is active app).

I expect "Firefox" to be used as the name for Firefox. Outside of Ubuntu, Mozilla's Firefox is ubiquitously referred to as "Firefox" and never "Firefox Web Browser".

By default, Windows 10, macOS 11.16, Fedora 33, and Flatpak versions/packages of Firefox all use "Firefox" as the app name for Firefox.

This bug from 16 years ago seems to describe the original change: https://bugs.launchpad.net/ubuntu/+source/firefox/+bug/7947

This bug provides rationale behind the original change, that "Firefox needs more description that just the name."

Browser makers such as Mozilla and Google/Chromium refer to their browsers as "Firefox" or "Google Chrome", respectively. There is no explicit mention of "web browser" within their name. This is likely as Firefox, and especially Chrome are very recognized names nowdays.

Note this issue is *not* about the name of the package itself (currently "firefox"). It is only about the name that shows in the GNOME top bar/menu/app launchers. It is the value for "[Name]" on the third line of /usr/share/applications/firefox.desktop

To fix this issue the default name for Firefox in the aforementioned Ubuntu packaged firefox.desktop file would need to be changed. Translations may also need to be adjusted which upstream should already have entries for.

Snap also uses "Firefox Web Browser" as its app name for its Firefox package, and is affected similarly. If this bug is resolved as suggested, the snap package should be changed too for consistency.
