Tab loads same webpage multiple times, preventing me from using back button.
Sometimes when I open a website, the tab will load the page 2, 3, 4 times or more. If I press the back button, FF will try to load one of the duplicate pages, which all try to force load the "last" page that was opened. For example, if the same page was loaded three times, the screen will show the page and my history will have two other copies of the same page. If I press back once the second page will load, which then takes me back to the third page. Press back twice, it takes me to the first page, which loads the second, which loads the third. The pages load too quickly for me to navigate out of them, so I have to close the tab.
