Collection of userscripts
You will need a userscript extension, like Greasemonkey, Tampermonkey or Violentmonkey.
Then just open the url of the script (see below) and it will ask to install.
You can also manually copy/paste the code.
Important
For chrome/chromium users (basically all except firefox/apple): Chrome disables userscripts by default, and you need to explicitly enable them. Sometimes you can follow the instructions on the extension itself (don't dismiss the blue warning!) or alternativelly check this faq; and/or search on the internet if chrome break them yet again. Remember to restart chrome if it still doesn't work!
If you don't want to install a browser extension, you can alternatively run the script in the developer console (you may need to 'allow pasting' before).
