I'm currently on a very old version of Firefox simply because the new versions, each time I try the latest versions, seem to not have the function the old one has. Remembering the websites I put into the address bar. The version I am currently using did have a issue with shuffling the order of the sites based on 'use' but setting Firefox to Private mode kept the websites locked in order and did not make them shuffle if one was clicked more often than another. Is this something I can do on the current version because I tried and looked for a way to do this recently but I kept getting 'autofill' results from google when I just want to be in Private mode, have the websites I frequent be the only ones listed when I click the address bar and not have them shuffle or have any other website I'd type into the bar not add itself to the list. If this is or isn't possible let me know.
