Unicode support is built into Mac OS X. You need to download and install Bangla unicode supported fonts with Apple Advance Typography (AAT) to enable it.

As a result you will not see Bangla properly on those browsers. To input Bangla you have to download unicode Bangla keyboard layouts. You can download some of the layouts from Ekushey.Org.

Also, make sure that you have a Firefox 2..0 or later, earlier versions have abug concerning rendering of Indic fonts.
