The Printliminator is a bookmarklet that gets any webpage ready to print. Once it's activated, you can click on elements you don't want to print to remove them from the page. If you don't want to do it manually, you can remove all images on the page using one button. Another button applies a nice default print stylesheet.

Sometimes there's only one element of a page that's worth printing, and The Printliminator has you covered there, too. Instead of clicking to delete one thing at a time, you can option-click to delete everything but what you're clicking on. If you make a mistake and delete something you wanted to print, there's no undo. Just reload the page and start over.

Firefox includes a built-in spellchecker that lets you know when you're misspelling words in an email or other text entry box. But what if you want to spellcheck an email that's already been sent or a web site that's already been published? All you need to do is enter a little Javascript code in your URL bar or click this bookmarklet, (which you can drag and drop to your bookmarks toolbar).

Once you've clicked the bookmarklet or copied and pasted the code, Firefox will turn on the spellchecker for the page you're currently on. All the words that are either misspelled or absent from the Firefox dictionary will be highlighted in red. And you can right-click on a word to see suggested spellings or even to "correct" it. Of course, any changes you make won't actually be saved to the web page, and the next time you load the page they'll be gone.

This trick can come in handy for web publishers looking to proofread their pages, or for nitpickers who enjoy pointing out the mistakes we make when we blog in a hurry.

There's a lot of rage directed at Internet Explorer 6 these days, including several very serious sites detailing the ways it's holding the web back and making designers' lives miserable. Sometimes rage isn't the best approach, though. Sometimes you need to have a sense of humor – or, if you're a designer who has to support IE6, laugh to keep from crying. That's where the IE6ify bookmarklet comes in.

When you IE6ify a site using the bookmarklet, you can see it breaking the webpage more literally than IE6 already does. Page elements shift and overlap, images are corrupted, and the whole layout generally just takes off directly for hell in a handbasket. The more times you click the bookmarklet, the closer you get to an experience as authentically horrible as actually using IE6.

"Daddy, what's a bookmarklet?" A childish question, perhaps, but not a question a child might ask. The kid might also call them favelets if he was raised on a diet of Internet Explorer. A bookmarklet, or favelet comes from "bookmarks" and "favorites" that you would save in your browser. Bookmarklets are Javascript applications in the form of URLs, and wherever you can store a URL, you can store a bookmarklet. Usually you drag them from the page to your bookmark bar, or you can add them like any favorite or bookmark.

A bookmarklet functions much like a button, but instead of just taking you to a website (like your garden variety bookmark), it does something at that website as well. As I said, it is an application. Some bookmarklets are used to modify a website, even if the effect is an illusion on your machine. Javascript can do some crazy cool things in a browser, and bookmarklets can similarly do some crazy cool things. Unfortunately each browser handles Javascript just a bit differently (and different versions of a browser will behave differently), so your mileage may vary.

Bookmarklets are commonly used to quickly tie into websites that allow you to share information. For example, this handy Delicious bookmarklet that allows you to easily save a URL to your Delicious bookmarks. Normally you'd copy the URL, go to Delicious, then paste it in to the right place and fill out the metadata. With the bookmarklet you simply hit the button (the bookmarklet in your bookmarks bar, or elsewhere in your bookmarks) and it will take whatever site you're on, send you to Delicious, and fill out the URL and title. It usually suggests some tags as well.

Lots of sites provide handy bookmarklets, including VodPod, Tumblr, Reddit and FriendFeed. But here are a few resources you might find handy or fun:

• The Internet Archive has a Wayback bookmarklet so you can see previous versions of a website instamagically (scroll down a bit).
• Prank your friends with the ability to edit any website (well, not Flash sites) using this fun bookmarklet.
• Opera users? Here's a pile of bookmarklets just for you.
• Ever wanted to read some text on a web page in big text, one word at a time? Check out the nifty Spreeder bookmarklet to do just that.
• Finally there's the spiffy Rollyo, which adds a search to any page you visit. Plus, you can save your searches for later.

If you missed it the first time, Lee recently put together a list of 15+ handy bookmarklets.

If you're a web design who works with grid systems all the time, it's handy to have a way to put a customizable grid over any website. I wrote about Slammer, an OS X tool for gridding up any window, and readers asked if there was a non-Mac alternative. Here's one: the web-based 960 Gridder. It's a bookmarklet, so it's cross-platform and works in all major browsers.

Once you turn on 960 Gridder, the default grid will be displayed on top of your browser window. To change settings, go to the 960 Gridder sidebar over on the left, and adjust colors, opacity, gutters and spacing to your liking. There's even an option to reverse out the grid, in case you switch from a light to a dark page. 960 Gridder isn't a perfect solution, but it's a free one, and it helps in a pinch.

Everyone knows about the power of Digg. We've seen it first hand many times here at DLS with waves of Digg faithful pouring in when a hot story hits the feed. Today, they've taken the gloves off and come out swinging at other short URL and social sharing services with the new Diggbar.

Apart from making it easy to submit items to Digg, the toolbar also integrates with Facebook and Twitter and can send links via email. There's nothing to install, just a simple bookmarklet that should work with any web browser. Click it and the page reloads with the Diggbar perched on top, ready to submit the page to Digg and share stats on previously dugg items.

A short URL is automatically created for the page, and the Diggbar has one big advantage over other competitors like TinyURL, bit.ly, and Is.gd: name recognition. There's no doubt that the service will benefit from not only from Digg's popluarity, but also from Kevin Rose's massive Twitter following and general "star power."

No need to visit Digg to view comments, either. Just click the button and they'll appear between the bar and the page itself. The bar also includes buttons to visit a random site or check out related Digg submissions.

As if that weren't enough, Thwirl integration is coming. Once it's live, users will be able to use Digg as their default short URL service. Since the features have been made available via Digg's API, developers of other apps can start taking advantage of it as well.

Maybe you don't think Diggbar will destroy the others, but there's no denying it'll make some serious noise.

Everyone's Twitter habits are different. Some people check the site once a day via the web, some people check it every 3 minutes using a Twitter client. If neither of those appeal to you, because you'd rather not have a separate app or even a separate tab open to view your friends' recent updates,Tweetpkr might be for you. It's a browser bookmarklet that loads your Twitter list in a sidebar on the page you currently have open.

The ability to check Twitter with one click, without changing focus, is more useful than it sounds at first. Each time you close and reopen Tweetpkr, it refreshes your list. That means no more jumping between tabs and hitting refresh, or winding up with a half-dozen Twitter tabs open. Privacy-conscious twitterers will also appreciate that Tweetpkr stores your username and password locally with the bookmarklet, not on its server. Oh, and multiple accounts are supported: just make a separate bookmarklet for each one.

Now that "web 2.0" has been around for a while, it's become apparent that even the most mundane features of desktop apps are going to be available through web-based services. You've probably seen the highlighting feature in word processors like Microsoft Word. Do you need it for web pages and blog posts, too? Markkit, the web highlighter, has got you covered.

Just drag the Markkit bookmarklet (try saying that 10 times fast) to your bookmarks toolbar, and click it whenever you want to highlight some important text on a webpage. You don't get to use a fancy highlighter icon as a cursor or anything, just select text like normal to highlight it in yellow. If you make a mistake, you can mouse over the text to reveal an "unmark" button. Your highlighted pages have their own Markkit URLs, so you can save and share them by bookmarking them in your browser or on a service like Delicious.

Ever have the urge to change a headline or rewrite the text of a web site? Edit this page is a browser bookmarklet that makes any web page instantly editable. Well, kind of. Here's how it works. Drag this bookmarklet to your bookmark toolbar. When you're on a page you'd like to rearrange, just hit the bookmarklet and you can edit any text area.

Of course, nobody else will see the edits you've made unless you take a screenshot and share it with the world. But in completely unrelated news we are particularly proud of the distinction Time Magazine gave us earlier this year, so we thought we'd share that with you.

For some baffling reason, Gmail still doesn't officially support HTML signatures. In other words, you can't add links, graphics, or adjust your fonts.

There are a handful of Greasemonkey scripts that add support for HTML signatures, and the latest version of Better Gmail also lets you create HTML signatures without installing Greasemonkey. But what if you don't want your signature to show up on every single message? Or what if you want to create multiple signatures that you can use in different situations?

GeekFG has developed a web service that lets you create and HTML signature and then save it as a browser bookmarklet. All you have to do is click on the bookmarklet when composing a Gmail message in Firefox or Internet Explorer and your signature will be added.

This utility comes from the same guy who brought us DomainFinder, a web service that lets you break up any word or phrase into possible domain names like downlo.ad/squad or downloadsq.ua/d.

Have your eye on the Macbook Air, but don't want to pull the trigger and buy one until Steve Jobs drops the price by a few hundred bucks? You could keep hitting refresh on the Apple Store page from now until eternity. Or you could have Price!pinx send you an email when the price changes.

Here's how it works. You drag a Price!pinx bookmarklet to your browser toolbar. Then whenever you visit a product page on any web-based store, you just highlight the price of the item you're interested in and hit the bookmarklet. The Price!pinx page will pop up and if you enter your email address the service will send you a message as soon as the price changes.

You can also register for a free account to manage all of your notifications in one place. But there's no registration required to set up a basic alert.

We heavily rely on RSS for easily managing our online resources. Thats why its great to learn about sources that can help us create feeds without any effort to keep things in order and manageable. Especially when websites might not have RSS feeds.

Feedmarklet is a way to set up your own RSS feed, and add content to it via a bookmarklet. It's as easy as creating the bookmarklet in your browser, pressing it whenever you come across good content, whether it has an RSS feed or not. The page you are visiting will get added to your feed with the Feedmarklet application extracting the page title and URL dropping it into a form. All you need to do then is write up a description (which can be done by selecting some page text before hitting your "add to feed button") and be on your RSS way.

Here's a neat little trick we picked up from Lifehacker. Since you can adjust a number of settings in Firefox by typing commands into the URL field, it turns out you can also adjust settings by saving those commands as bookmarks.

Say you want to create a bookmark or a bookmarklet for your toolbar that will let you resize your browser window. Just right click on your toolbar and select "New Bookmark."

A window will pop up allowing you to set a name, description, and location Just enter the following into the location field " javascript:window.resizeTo(800,600);" but leave out the quotation marks.

Change the numbers to set your default resolution. Now you can easily switch between full screen and windowed mode at the click of a button. If you want to see how a website looks at different screen resolutions, you can create a series of these bookmarks.

What other Firefox settings adjustments would you automate by creating a bookmark?

Many enthusiastic web surfers know that the venerable Internet Archive is the home of the Wayback Machine, a tool that allows you to go back in time with a particular website to see what previous versions looked like. What we hadn't noticed until today is that the Wayback Machine has a bookmarklet you can use when viewing any site to quickly check if there are archived versions of it. The 'marklet can be had farther down on the Wayback Machine site, and the convenience it adds should prove useful to surfers who are curious about the history of a particular site.
