Best Greasemonkey scripts

Greasemonkey is a Firefox extension which allows the user to customize the look and functionality of web pages by installing scripts. Hundreds of Greasemonkey scripts are available at UserScripts.org and you can also write your own. The following are some of the best greasemonkey scripts that I found at Userscripts.org :

Show Password on MouseOver ( Install )

Moving the mouse over a password fields reveals the password text. Useful for viewing the login passwords stored by your browser.

YouTube “Lights Out” ( Install )

Adds an icon to the you tube video page, that greys out the rest of the page when clicked. This allows you to watch the video without any distractions. Click the icon once to change background to dark grey, click the background to change it to black, and click the background again to return the page to normal.

Flickr “Lights Out” ( Install )

Same as YouTube “Lights Out”. Works for Flickr.

Google Image Relinker with Mouseover ( Install )

Changes the links on the results page of google image search, so that they point directly to the original image. Hovering the mouse over a thumbnail shows a pop-up preview, and clicking on the thumbnail opens the original image in a new tab.

SkreemR 2.0 ( Install )

Cleans up the SkreemR.com search results page.

Inline Mp3 Player (WordPress version) ( Install )

Replaces links to mp3 files on any webpage with an mp3 player!! Very useful for previewing mp3 files before downloading.

Apple Trailer Download ( Install )

Lets you download trailers from Apple.com. It displays a small popup near the bottom right corner of the page, that contains download links for the video.

PirateHelper for GreaseMonkey ( Install )

This script does the following:

• Removes ads and other useless stuff
• Sorts search results by number of seeds (highest to lowest)
• Removes torrents with 0 seeds
• Resizes the search results table to fill screen width

Must-Have Firefox Addons for Power Users

Omnibar

Omnibar combines the address bar and search bar into a single bar (like what you have in Chrome). You can type search terms into the address bar and switch search engines with a single click. It displays suggestions for URLs and search terms as you type.

Speed Dial

This add-on brings Opera’s speed-dial feature to Firefox. Its very customizable. You can change the grid size to display any number of pages.

Tabkit

Tabkit displays all open tabs as a tree on the left-hand side. The tab bar at the top is removed which provides more vertical space for viewing web pages (useful for widescreen displays). All tabs from the same website are grouped by color and child pages are indented to form a tree like hierarchy. Browsing websites using a folder like tree structure may take a little time to get used to, but once you get used to it, it feels more natural than using a tab bar.

Note: Its not as ugly as it looks in the screenshot. You can remove the yellow and black highlights from the tab names, customize the colors and tweak other options.

NetVideoHunter

There are dozens of firefox addons for saving videos from websites. However this addon is my favourite and has never failed me even once. It can detect the download URL for any type of video on any website. It provides both the download URL and a button for saving the video to disk. You don’t even need to watch the entire video to download it. Just wait for the video to load (NetVideo hunter will detect it within seconds) and then click on the Download button to save it.

Adblock Plus

This addon needs no introduction. Adblock Plus blocks advertisements on webpages, making pages load faster and saving a lot of bandwidth. Ads are blocked on a web page using filter rules which define which item on the page is an ad and which items are not. There are a number of ready-made filter lists available which the user can subscribe to (for free). These lists block most of the adverts on web pages. In case they miss some, you can right-click on the ad and add it to the block list, and the ad will never be displayed again.

Flashblock

Flashblock replaces flash objects on web pages with an icon that can be clicked to download and view the flash content. Since flash animations are rather large in size they waste a lot of bandwidth and can also be very annoying. Most of the flash content on web pages consist of advertisements. Some websites have many videos embedded on the same page which start playing as soon as the page loads. Since most videos are displayed used a flash-based player, flashblock can block them too.

Download Them All (dTa)

The ultimate download manager for Firefox. Breaks up downloads into multiple parts and downloads them simultaneously to maximize the download speed. You will really max out your connection using this download manager. The graphics are cool too. Moving the mouse over a download shows a cool graph and other statistics. Also useful for bulk downloads. It can show a list of all download-able items on a page and let you select the items to download based on file type or url mask.

Note: Some servers don’t support multi-part downloads (free downloads from rapidshare for example). For downloading files from such servers, it is better to use the default download manager.

Download Statusbar

Firefox’s in-built download manager is very slow (compared to dTa). But if you don’t mind using it then the Download Statusbar addon is highly recommended. Instead of displaying the download status in a popup window, the information will be displayed neatly in the statusbar.

Scrapbook

Helps you create a scrapbook of all your favourite web pages and browse them offline.

It is very useful for collecting information on any topic from the internet. With a single click you can add any useful pages that you find to the scrapbook,  and browse them later at your convenience. Its a lot more convenient than creating bookmarks or keeping a lot of tabs open for later use.

The most useful feature of this addon is the “Edit before capture” option that it adds to the statusbar. On selecting this option a toolbar is displayed for editing the webpage. Using a tool called the DOM Eraser you can delete any element from the page with a single-click. This tool is extremely useful for deleting useless items from a webpage before taking a printout. It lets you delete banners, ads, sidebars, etc with a single click and take a clean printout that contains only the information that you need.

Skipscreen

A very useful add-on. Skips through useless pages on file sharing sites like Rapidshare, Megaupload, zShare, Mediafire, and more. You still have to wait in order to download from these sites but this add-on makes the whole process simpler. You can leave the tab open in the background and the add-on will click through the intermediate pages and start the download.

XMarks

This addon stores all your bookmarks on an online server that can be accessed from anywhere in the world. It is very easy to use. Simply install it and forget it. Your firefox bookmarks will be automatically synchronized with the online server whenever you go online. It can also backup site passwords that are stored by the browser. It has addons for IE, Chrome and Safari browsers also. Once installed XMarks will synchronise bookmarks (and optionally passwords also) across all your browsers and PCs without requiring any attention. A must-have addon for all Firefox users.

GreaseMonkey

GreaseMonkey is an addon that can change the appearance and functionality of websites using user-defined scripts. Installing and activating a script will either modify the appearance of some site (improve the layout) or it may add some extra elements to the page (like a download button for downloading YouTube videos). Hundreds of scripts are available which do many different things. Check out the scripts at  UserScripts.org.
