I don't know how or why these things happen but I would like to restore it. I can find how to restore Bookmarks but not History. Thank You PS >>Also , the open "Window in a new Tab" doesn't work although I ticked it in the general options. I have to click on the + sign first to get a new tab and then put the url in which is annoying as I often forget and it just overwrites the tab I was on. Or if a link in an opened page I need to right click and click on "Open in a new tab"...... In Avant Browser when this feature is enabled it automatically opens a new tab which is a lot more convenient and efficient. Thank you Annabel
