I stumbled across an issue with Bootstrap Glyphicons not working with Firefox but working with other browsers faultlessly.
Q:How to make Glyphicons from Bootstrap 3.1.1 work with firefox?
(I answered this myself and this was part of the original post) When i sought information as to what might be causing this issue there are only a few articles that did not solve my issue focusing mainly on older versions and not explaining the required fix.
I then after some time worked out that by solely removing the 'www' from the <link href='www.domain.co.uk'>
to the bootstrap.css
the glyphicons began working within Firefox as well.
This appears to be due to the following error:

I thought perhaps this worth sharing as seems there has been a fair number of people with similar issues as myself without there being any articles covering this method of fix.
