I’m using Firefox 33 and have noticed that when you visit a post and then use the back button to return to the previous page, you only get a blank page.
1. Go to https://pub.photography/
2. Click on a post
3. Press the back button
4. The page fails to load and you get a blank page. You are able to view the source of the page and all of the HTML code is present.
I was not able to recreate this bug in Chrome 39, IE11 or Opera 24 but I was able to recreate it in Safari 5.1.7 on Windows.
