I was doing some research on Microsoft sites related to Microsoft Azure. I noticed that it became difficult to go back using the back button because each page was listed in the history twice. For instance, on this page: https://azure.microsoft.com/en-us/services/virtual-machines/ This made it exceedingly frustrating to navigate the site as I could never easily go back to the previous page. At first I thought it was something the Microsoft site was doing (and maybe it still is) but I do not see this same behavior on Chrome or Opera. I have tried this on the latest versions of all of the above making sure to update each before listing my problem here. Is this a bug in Firefox still allowing some level of history hijacking or manipulation? Or is there some setting, extension, etc. that I need to look in to in order to fix this problem? Thanks
