hello RWELTON, can you try to replicate this behaviour when you launch firefox in safe mode once? if not, maybe an addon is interfering here... [[Troubleshoot extensions, themes and hardware acceleration issues to solve common Firefox problems]]

There is no back button on the tab.<br /> There are Back and forward buttons on the Navigation Toolbar where the Forward button is only visible when there is such a page available (i.e. you have used the Back button at lest once). *https://support.mozilla.org/kb/How+to+customize+the+toolbar *https://support.mozilla.org/kb/Back+and+forward+or+other+toolbar+items+are+missing Can you attach a screenshot? *http://en.wikipedia.org/wiki/Screenshot *https://support.mozilla.org/kb/how-do-i-create-screenshot-my-problem Use a compressed image type like PNG or JPG to save the screenshot.
