For archiving a page:

  javascript:void(window.open('https://web.archive.org/save/'+location.href));

Should probably encode the href but it has worked so far

Hmm, just tested this variation:

    javascript:void(window.open('https://clearthis.page/?u='+location.href));

and it works to invoke ClearThisPage: https://clearthis.page/

    Bypass the clutter from any web article

    This service takes any web article or news page and returns only the relevant content, freeing you from any clutter, including ads, popups and more.

which also sidesteps some (not all) paywall blocking markups.
