User reviews
This extension is amazing! I've been looking for a utility like this for years. In order to receive interest on my checking account, my bank requires me to use the bank's debit card 15 times a month with a minimum purchase of $15 each or, have a total of $500 worth of transactions. I seldom can make the 15 transactions but I can however most of the time meet the $500. With this extension all I have to do is hold down the control key while I go through my online bank checking account overview and see a running total of my debit card amounts! Fantastic!! Thank you so much for this timesaving utility!!

Love this extension and use it regularly. Would love a cross-browser version though ;-)

There is no data format setting, which is why, if the time in the cells is in hours and minutes, the add-on cannot calculate the sum (total time).
