Hi, I've noticed couple of bugs. One is the Stub template, which in wide-screen monitors messes with the article. Changing the size of the image to 45px might resolve that, but then it would look weird in the 4:3 monitors.
The other is the favicon thing, it won't show the correct icon in the bookmarks, or in the bookmarks toolbar (even though it shows the correct icon in the tab). I'm guessing it's more of a Firefox problem since it is working perfectly in the IE and Edge. I don't have an idea how to fix that though, maybe reuploading the icon helps.
Adding the article name fixed the stub template. Thanks.
Could I trouble you to edit "Template:PoP series" a little. The "Prince of Persia: The Sands of Time" links to the disambiguation page. I also added pages for "Prince of Persia: Time Run" and "Prince of Persia: The Sands of Time (GBA)", those could be added to the list.
