Bootstrap 3 unable to display glyphicon properly
I am migrating from bootstrap 2.3 to bootstrap 3 and everything works well. But when I tried to add some icons, the icon font doesn't displayed properly. I tried to look over here http://bootply.com/61521 and only '.glyphicon-envelope' was being displayed properly. Others have displayed like 'E001' and so on.
How can I be able to solve this problem?
For other browsers, glyphicons are displayed properly, only firefox was unables to display it properly.

Did you choose the customized version of Bootstrap? There is an issue that the font files included in the customized package are broken (see https://github.com/twbs/bootstrap/issues/9925). If you do not want to use the CDN, you have to download them manually and replace your own fonts with the downloaded ones:
https://netdna.bootstrapcdn.com/bootstrap/3.0.0/fonts/glyphicons-halflings-regular.svg https://netdna.bootstrapcdn.com/bootstrap/3.0.0/fonts/glyphicons-halflings-regular.woff https://netdna.bootstrapcdn.com/bootstrap/3.0.0/fonts/glyphicons-halflings-regular.ttf https://netdna.bootstrapcdn.com/bootstrap/3.0.0/fonts/glyphicons-halflings-regular.eot
After that try a strong reload (CTRL + F5), hope it helps.
