Add-on that displays links on goodread pages, which link to searches on an arbitrary, configurable website.
This can either be installed as an add-on on Firefox and Chrome or as a userscript.
You can configure the settings for the search links! Just click this add-on's icon in the top right corner of your browser.
To configure the search site and the search settings you have to modify the
script a little bit. Head to your userscript manager's dashboard, edit this
script, and modify the variables SEARCH_SITE, SEARCH_PARAM, inclAuthor,
and searchParams. See the comments for more infos.
