There was a problem hiding this comment. Are examples not run through pycodestyle? This is definitely too long. There was a problem hiding this comment. apparently not. I think this ok to leave as a long string as it is input data and not meant to be human readable/editable anyway. Either your editor will soft-wrap it (in which case it takes up the same visual space as if we had wrapped it by hand) or your editor truncates it, and then it takes up only one line and there was much rejoicing ;) |

This address redirects to the main page. And clicking on "Free Icons" gets me a 404 error. I see no information about licensing. I am almost certain that firefox icons from mozilla aren't compatible with BSD-like licenses (which is why the BSD OSes ship with rebranded Firefox).
