I’m addicted to browser tabs. I probably open several hundred of them each day during my regular web browsing. And today brings good news: Google wants to reward me for that.

Well technically, Google wants to reward charities on my behalf for my obsessive web browsing. A new initiative today called “Chrome for a Cause” asks you to download a Google-made Chrome extension that will note your tab opening activity and allow you to donate to one of five charities at the end of each day based on your usage. Yep, just browse the web, and donate to charity.

The charities involved in this are: The Nature Conservancy, charity: water, Doctors Without Borders, Un Techo para mi Pais, and Room to Read. Here’s Google’s breakdown of how much you have to browse to donate to the various charities:

• 10 tabs = 1 tree planted
• 10 tabs = 1 book published and donated
• 25 tabs = 1 vaccination treatment provided
• 100 tabs = 1 square foot of shelter built
• 200 tabs = 1 person’s clean water for a year

The initiative will run for five days from December 15 to the 19. Google says they’ll donate up to a million dollars on behalf of the extension’s users.
