Debian Firefox ESR not used

[gogglespisano]

On Debian, Firefox ESR is normally installed. In /usr/bin/ there is "firefox" and "firefox-esr". When find_firefox() sees "firefox", it tries to use it and fails. It needs to find and try "firefox-esr" first.

The follow change in marionette.py line 111 fixes the problem, and should still work for a regular firefox installation.

def find_firefox(cls):
    candidates = where.where("firefox-esr")
    candidates += where.where("firefox")
    candidates += [
        "/Applications/Firefox.app/Contents/MacOS/firefox-bin"
    ]

Dear Stuart,

apologies for the late reply. We just added f78451198a2fa, after the same problem tripped @intermittentnrg when running grafanimate in Docker.

With kind regards, Andreas.
