My firefox is not recalling the history as I move through tabs. It doesn't appear in the sidebar or in the documented history. This only has happened recently, and it's still recognizing my bookmarks. I've done some troubleshooting, tried relaunching in the mode while switching through tabs, but it's still not recalling. Any help is appreciated.

On closing down firefox. My browsing history still remains.I have all the boxes ticked that need to be ticked to perform this.Settings also are all ticked and saved. it was all working fine 2 days ago. came back ontoday and stopped working. can any one help. Also my firefox icon/tile/shortcut in my taskbar has changed from firefox icon to being a white folder with top right coner folded over.Anyone have any ideas whats going on.
