From Padma’s official website,
Padma is a system for transforming Indic text between various public and proprietary formats. This extension applies the technology to Mozilla based applications. Padma is available as an extension for Firefox, Thunderbird, Netscape, Mozilla suite and SeaMonkey platforms. Padma currently supports Telugu, Malayalam, Tamil, Devanagari, Gujarati, Kannada, Bengali, and Gurmukhi scripts
This particular version includes support for Marathi TrueType Font – Shree-Dev-0714, which I wrote last summer. I am happy that it is finally Padma core. A big credit goes to Radhika Thammishetty and Harshita Vani for guiding and helping me out in writing the mappings.
