my firefox just updated today all my existing tabs loaded correctly and are present, however I cannot make new tabs- they do not display or load by any command and i cannot toggle over to them when switching through existing tabs. it is as if the new tab command is not executing a new tab now. a site on an existing tab can create another tab, such as what mozilla did while i was searching for answers to this question, but i cannot make any new tabs via keyboard or menu command.

i need to make new tabs and not use existing tabs which are already in use!
