Greetings to the Firefox community. I would be needing help to know if it is possible to restore the Browser to some earlier date. I had an Application installed that every time I opened a new tab it served as a Notepad, there I had written several things that served me. When doing an update of Firefox this application is no longer, with which I lost that information that served me to be able to work. Addresses, websites, notes in general. Try to restore the Operating System (I have Windows 10), but it has not been very useful. I would like to know if there is any possibility of doing so and how is the procedure. Thank you very much to those who help me. Greetings from this side of the planet. And happy # 2020 to all.
