You'll need to install the Greasemonkey (Firefox) or Violent Monkey (Chrome, Yandex and Opera). Then add a new script and copy & paste. All dynamic contents are removed; so be sure to add to the "NOT_TO_REMOVE" list the iframe src's that you do want to see! Or you may add exceptional line(s) like this within metadata block:
// @exclude http://www.example.com/foo/baz
Now your browsers should be totally quiet without any unwanted moving stuff. Timers are removed too!
