I have Windows 11 on my computer, it is up to date, and I have downloaded Firefox several times and yet it keeps telling me it has a problem, shuts down and restarts . I have lost many downloads and emails because of it. I just made an e mail and just before I finished it to send, it told me there was a problem, it needed to restart and the email was lost. The same is with Windows 11. I have downloaded it many times, saved pages , news etc. and when I open the document or item, it tells me that I need to update my browser It is not my computer. I have even at times done Recovery and eventually have the same problem app
