Firefox & Bootstrap 3 Glyphicons
I’m currently working on a site which uses Bootstrap 3, and makes significant use of glyphicons. As of Bootstrap 3, glyphicons are back to being web-font based. They look fine in Chrome (which is my main desktop browser), and in Safari on iOS, but I recently noticed they didn’t work on my Android phone. Initially, I thought it might be an Android problem, but then I spotted that they didn’t work in desktop Firefox either.
