Combined character of tamil letter looks to be correctly supported from Firefox 3. Bug 470407 sounds for me same problem as yours.
> Bug 470407 Tamil characters like " கொ(ko),கோ(kO) " are messed up

Is complex script enabled in your installation of Windows (in Settings |
Control Panel | Regional and Language Options | Languages, is the checkbox
"Install files for complex script and right to left languages.." checked?). IE and Firefox 3 support complex script even if it's not enabled in the OS, but Firefox 2 and below rely on the OS support.

Seebug  report 470407

check your old profile and the new profile in your profiles directory in C:\Documents and Settings\ user....\Local Settings\Application Data\Mozilla\Firefox\Profiles. the problem went away in bug  report 470407 as the old profile was causing ff3.0.5 to display improperly while 2.0.0.20 was ok.  I do not know what exactly was the cause as the old profile was accidentally lost
