I have a few suggestions -Set the browser home page to Trisquel's all-manuals page: https://trisquel.info/en/wiki/all-manuals
Put free-sw-friendly websites in the bookmarks. For example, for music : bandcamp.com , Jamendo (please correct me if these websites are not good suggestions)
Consider bookmarking Jason Self's website too: http://www.jxself.org/archive.shtml
