Some words aprears with a link to marketing sites
when I use the Firefox, some words in the text (in all pages I access) appears with a link to commercial or marketing sites, always unwanted. How do I remove those unwanted links? Thanks

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.
