Q401: Tampermonkey slows down my computer. What can I do?

A401 This is a known issue caused by the iframe support of Tampermonkey (and by the way Greasemonkey too ;)). In order to avoid Tampermonkey to check and most probably run scripts at unwished iframes you can do a lot of different things:

• Avoid No global includes Try not to use scripts that @include all pages (http://* and https://*) cause these scripts will run at every tab, every frame and every advertisement. Note: Tampermonkey outlines such scripts by this icon <i class= *"fa fa-globe fa-lg"* aria-hidden="true"> at their sites column.

• Make Tampermonkey not run at social buttons Open TM's options page, make sure the "Config mode" is at least set to "Beginner", go to "Settings" and extend the "Blacklisted Pages" text area like this

  *://apis.google.com/_/+1/*button*
  *://www.facebook.com/plugins/*
  *://platform.twitter.com/widgets/*
  

• Exclude advertisements You can try your own excludes based on this:

  *://*.doubleclick.*/*
  *://*advertising*
  *://*banner*
