UserJS for Flickr: center the full size picture and kill the topbar

  This script centers the full size picture vertically (if the photo is bigger than the screen) and kills the topbar that obscures the view. It's triggered with a click on the page (except links).

Flickr old design. Greasemonkey Script for Firefox

  Flickr is not usable with the new design, which is, btw, an example of the epidemy of moronic blunders made by big internet/computer companies: from Microsoft's Windows 8 Metro interface (created for cats and monkeys playing with tablets) to Opera 15 (a browser without... bookmarks - lol).

  To get some of the old, normal usability of the Flickr website, you can add "?details=1" suffix to the profile address and "detail/" to the "set" view address. This script (which works also in old Opera) can be used to do it automatically. Install the script and and press the key "q" or "5" to get to the old design on "photostream" and "set" (sometimes you have to press the key twice or more times to get it quickly).
/Note: I changed the shortcuts from "f" and "3", because flickr uses "f" as "favorite" and 3 may be already taken in Opera , too)/
The script also allows to get to the bigger-size version of the pictures after pressing the same keys.
  Another script below does this automatically after loading without the necessity to press any key (but may be buggy on some flickr pages).

UserJS: Google search inside a specific website

   Use this User JS.  The script asks for the search word and a website (it uses the selected word and  the current website as default).
