I believe this is the stub (~400Ko)

Sniffing my laptop gave me this http://download-installer.cdn.mozilla.net/pub/firefox/nightl...

Felt weirdly generic since the name didn't indicate any special edition, but I ran it and it says developer edition.

tl;dr In case someone needs an offline installer, grab that url.

The subt stopped downloading in my crappy connection and gave me this link to the installer: https://ftp.mozilla.org/pub/mozilla.org/firefox/nightly/late...

Edit: Use the custom installation option to prevent it from becoming your default browser.

All that work for nothing, if only I had a crappy connection :)

I hope your laptop smells nice.

I'm sure you meant sniffing your network traffic?

Edit: Oh man I think I've hung out with the Python crowd for too long I think their rancor is starting to rub off on me ;)

Thank you, as someone who develops almost exclusively offline, this was crucial ;)

Thank you so much! This was so needed on this horrible internet connection I have here at work!
