Source Make Tabs Permanent In Firefox
Firefox by default handles all tabs the same way. A tab gets closed if a user presses the close button, no matter if that action was intended or not. It is also true that new websites get loaded in the active tab under certain circumstances which is another thing that some users might want to avoid in certain situations. The PermaTabs Mod add-on for the Firefox web browser can make tabs in the web browser permanent so that they cannot be closed by normal means. The default setting disables the right-click close tab button, nullifies the action of the close tab icon at the end of the Firefox tabbar and ignores the close all other tabs command for permanent tabs. In short, it makes it impossible to close the tab unless the permanency of it is disabled beforehand.
