An extension to keep track of all those 'for-donation' sites you visit
When people use websites that rely on donations, they often overlook how often they use the site. How many times a day do you use Wikipedia? This extension merely acts as a reminder of how often you really do use these sites, and allows you to easily calculate a suggested donation amount based on the frequency of your visits.
Simply add a website to the tracked list, either by going to the page or typing it in, and add what you think the website is worth per visit. By default, it is $0.03, but you can change it as much as you want.
