No mousewheel? No problem! This script will scroll the page if you place your mouse near the top or bottom of the window and wiggle it.

Minor visual tweaks to StackExchange (remove the new sidebar from Q/A pages, for classic look)

The red notifications dots on Quora are annoying, so let's make them grey. Also hide the popups, separate adverts from content, don't keep opening new tabs, and add some whitespace for readability.

Scroll entire page smoothly with long left-click and drag.

On pages which do not have a Table of Contents, but should do, create one! (I actually use this as a bookmarklet, so I can load it onto the current page only when I want it.)

If a tab is unused for a long time, it switches to a light holding page until the tab is focused again. This helps the browser to recover memory, and can speed up the re-opening of large sessions.

When you paste a URL to a friend, it is useful if it contains the title of the page. This script adds these missing titles for common websites using # part of URL. In other words, it turns non-semantic URLs into semantic URLs!

When it sees a link to a userscript or general Javascript URL, adds a Bookmarklet besides it, which you can drag to your toolbar to load the script when you next need it (running outside Greasemonkey of course).

Adds a hover event to internal article links on wikipedia pages which, opens the article inline in a dhtml frame.

Read articles hands-free! Pres Ctrl-Down or Opt-Down to start slowly scrolling the page. Press again to adjust speed. Escape or Space to stop.

Adds a favicon for the website next to every external link on the page. Clearly shows when you will be leaving the current site, and where you will be going! (Unfortunately making links longer than expected can result in unwanted overflow on various websites. For example, Google header bar!)

Adds movie ratings and number of voters to links on IMDB. Modified version of http://userscripts.org/scripts/show/96884

Navigate sideways! When you click a link, related links on the current page are carried with you. They can be accessed from a pager on the target page, so you won't have to go back in your browser.

Extends DDG by adding a customizable list of additional search engines for making fast searches from other engines.

Puts the video title in the location bar of all YouTube video pages. Now with extra features add scrollbars, animate thumbnails, reduce font sizes and un-float the header.

Four visual improvements for Wikipedia (and other wikis): Indents sub-sections to make the layout clearer. Hides the sidebar (toggle by clicking the header). Floats the Table of Contents for access when scrolled. Converts heading underlines to overlines.

Adds the likes/dislikes light-saber to YouTube thumbnails, so you can avoid watching crap videos. Activates when mouse passes over a thumbnail.

Tampermonkey keeps asking us to select an account when we open the browser. But this script by Jack'lul will do it for us!

Quick scroll to next/previous image on a page with n/p buttons

When clicking the notifications icon, displays notifications in a dropdown pane, without leaving the current page.

For any links (<A> tags) on the page which point to an image, show the image!

Adds favicons next to Google search results. Also works for Ecosia, StartPage and Searx.
