hi 12parsa, first of all thank you for your interest in supporting mozilla!

i think for this cycle there won't be any new payment providers added, as the donation campaign is drawing to an end soon. if you want to provide more feedback about this, as i think this is very valuable, please write an email to donate@mozilla.org - this will be read and answered by people directly involved in planning those donation-raising campaign in the future as well. thank you!
