Created attachment 8581694 [details] screen_capture.webm User Agent: Mozilla/5.0 (Windows NT 6.3; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/41.0.2272.101 Safari/537.36 Steps to reproduce: 1) Go to affected site 2) Browse to a page of the site 3) Try and go back clicking the back button Tested with clean, new profiles in Firefox stable (36.0.4) and nightly (39.0a1/2015-03-23/e730012260a4) with same result. No Flash installed. I also tested with Firefox 31-35, Chrome 41 and IE 11, which don't show this behavior. Example affected sites: androidayuda.com, adslzone.net, elotrolado.net, testdevelocidad.es Actual results: About 70-80% of the times, back button won't work, that is, it won't load the last page. From my observations I couldn't work out why it's not reproducible 100% of the time. Maybe it has something to do with the different ads Google loads. If you open the Network panel, you can see a new request to http://googleads.g.doubleclick.net/pagead/ads when you click the back button. I know the steps to reproduce are a bit fuzzy and the bug somehow doesn't always happen, so I'm attaching a screen capture with the hopes it clarifies something. Expected results: Back button should work normally, loading the last page.
