Thanks for reviewing my addon.
Your request looks like very interesting, but I have a question.
"links' article" - Does this mean Reader View(https://support.mozilla.org/en-US/kb/firefox-reader-view-clutter-free-web-pages)?

Sadly, Reader View cannot be available in special pages (e.g. popups and sidebars) due to the security policy. If mozilla supports this in the future, i will add Reader View mode.
