Is version 3.0x reached end of life? We need to determine from which version and above should we be making our app compliant. TIA.

Yes, support for the Firefox 3.0.x branch has been ended and updates are no longer released. Only 3.5.x (currently 3.5.14) and Firefox 3.6.x (3.6.11) are currently supported and still receive updates.
When Firefox 4.0 gets released (end this year or maybe next year) then support for Firefox 3.5 will end as well about 6 months later.

Yep, 3.0 is EOL now. Depending upon the type of app you have, you need to keep in mind that some users might be using 2.0.0.20 with Win98/SE/ME and Mac OSX 10.3.9 and earlier.
