Host has incorrect headers (?)

[yusuf.a2380]

Hi. My site www.yusufali.co.uk on Firefox the menu icons appear as Letters. whereas on chrome, IE safari etc. they appear as icons.

the font file is .ttf, the theme developer says the following message:

If it's only in Firefox then this file may not have correct headers set. Please contact your hosting company and let them investigate that. I also see that you use some caching/minifying plugin but it seems to work fine.

TrueType doesn't have a registered MIME type. To find out whether the problem is the headerYou can try adding this line to your htaccess file:

AddType application/x-font-ttf .ttf

That will send a content-type header of "application/x-font-ttf", which should be unnecessary. (The "x" indicates "experimental"; it was never adopted but should be harmless for user agents that don't expect it.) But shouldn't Firefox be using WOFF anyway?
