Happened again today (after latest updates). Wife was on a web page that required logging in. She closed Firefox as she was done with a web page (secure, online account, first time logging into that page) and then went to restart Firefox. She got a message telling her that Firefox was already opened and to restart the computer. She restarted the computer and it went into
and to manually check the disk for errors. I typed in
to manually check the disc and several errors came up (I had to press
as I didn't use
after fsck) and the system did a successful boot up. (I don't remember the errors as there were several). I had Timeshift enabled and was able to choose a time of this morning.
Because the wife was logged into an online secure account, perhaps there was a reason Firefox would not shut down after she logged out of the webpage and closed Firefox (clicking on red X top right corner rather than on exit from the file menu). Any ideas why this has happened?
Thanks
