Even though I use Firefox for most of my browsing, I am forced to jump to IE for browsing some of the Tamil sites like Vikatan, Kumudam & Dinamalar etc., because these sites use proprietary fonts that work only with IE. But thanks to Saravanan, I am now able to browse these Tamil sites through Firefox itself.
Saravanan pointed me to Padma font and a greasemonkey script both of which helps to view the proprietary Tamil fonts in Firefox.
Now I have one less reason to use IE.. Thanks for making that possible Saravanan.
