Automatically opening sites
Even after logging out , if I keep my computer ON , after some time some unnecessary sites, particularly Ad sites open automatically. What setting I have to correct?

hello, this sounds like a problem possibly caused by adware on your pc.
please go to the firefox menu ≡ > addons > extensions & remove any suspicious entries (toolbars, things that you have not installed intentionally, don't know what purpose they serve, etc).
also go to the windows control panel / programs and remove all toolbars or potentially unwanted software from there.
finally, run a full scan of your system with different security tools like the free version of malwarebytes & adwcleaner.
