Very good BUT does not work with FF ver > 4... Rated 2 out of 5 stars
Very useful calculator
...used for a long time in FF 3.6x.
BUT does not work with FF versions
greater than 4, anymore.
...and certainly NOT with FF 9.01.
What a pity!
And the Author, Sunny Goyal is oblivious to his users.
Not a word or updates from him...
- will you update your extension to work with FF 9+ ?
thank you for any feedback or answer.
