Adds a button to Steam profile pages to calculate that user's total playtime. It's based on my previous work on my Total Playtime website, using a lot of the same code from it.
How to use it! 1. Install the extension. Currently there is only a version for Firefox, I don't want to pay $5 to get it on Chrome just yet. 2. Visit any profile page on the Steam Community website. 3. Click on the "Total Playtime" button on the right side. 4. Profit?
