Wrong detection of User Agent

[dumblob]

On the page https://hubl.in/ , I can't use hublin, because it incorrectly detects my User Agent (Your browser seems to not be compatible. Please upgrade your browser experience to a compatible browser:).

I'm using firefox 44.0.2 and e.g. https://appear.in/ does not complain about anything and it works like a charm (I'm using appear.in for more than a year already).

This is strange, just tested with FF 45 without problem.
We use modernizer.js to detect browser compatibility and FF has always been in the scope. On which platform are you using FF?

Well, it's strange. If I move ~/.mozilla/firefox away and start a clean Firefox 44 session, hubl.in seems to work. If I move my original configuration back to ~/.mozilla/, it doesn't. I've tried to disable all Firefox plugins I'm using (HTTS everywhere, Privacy Badger, uBlock origin, Pentadactyl, Bamboo Feed Reader, and Zoom Page), restarting Firefox afterwards and hubl.in still doesn't work.

It might be then an issue with my about:config settings (even though I'm not aware of any manual changes) or rather with JS (or modernizr.js) doing some weird stuff as this is the output from http://whatsmyuseragent.com/ :

https://hubl.in seem good for me.
However, when I try to build it locaclly, and open in browser, It tells me that Your browser seems to not be compatible, just with the same browser...
I try both firefox 45 and chromium 49, and they perform the same way.

it seems like you have an error when you make npm install! i had this issue, try sudo bower install --allow-root
