Big problem with gkmenu when i acces the site without www

I have a problem with my site when i access the site without typing the www. When the site is loading home page for the first time the menu is a mess, but when i click on home button it redirects me to www. and everything looks normal as it should. This happens only in firefox.

My site: http://www.tractarislatina.ro
J 2.5.8

Here is an example:

With www:

tractari2.jpg

Without www

tractari1.jpg

I solve this issue by putting in .htacces below the
RewriteEngine On

RewriteCond %{HTTP_HOST} ^domainname.com
RewriteRule (.*) http://www.domainname.com/$1 [R=301,L]

Hi,

Other solution (also uses the .htacess file) is described here: http://www.fontsquirrel.com/blog/2010/1 ... e-problems (section "Fonts not loading in Firefox or IE9").
