i lost my previous tabs and i couldnt recover them. they were no were to be found in history. i need to restore tabs to a previous time or date to recover them and there is no such option, as i accidently closed the new tab and now its overwritten " previous" tabs.
I don't know the extent to which support articles will help with older versions of Firefox. Here are links to two articles and a comprehensive answer to a previous question on the topic.
