I need to add to firefox plugin collection the plugin like this one [url removed, login to view] but for new version of Mozilla. So you need to create the plugin for [url removed, login to view] with all the same features like Quick Sum but with a different name. Install Quick Sum to test it.
Will work with you on a long term basis cause i may need to update the plugin for other future versions of Mozilla.
Budget: 40 USD
Term: 2 days
