Bookmark

Bookmarklets are useful tools. Simply put, they’re bookmarked links you keep in your browser toolbar that perform a useful function when you click on them. There are about half a million of the things out there—far too many to fit in any bookmark toolbar! Let’s take a look at twenty of the most useful bookmarklets out there.

To “install” a bookmarklet, drag the link presented on the bookmarklet’s Web site to your bookmarks toolbar, and you’re done.

1. WordPress Bookmarklet

With the release of WordPress 2.6, the team at WordPress reinstated the “Press This” bookmarklet—this time even more powerful, with Tumblr-like capabilities. Want to throw a YouTube video or Flickr pic into your blog real quick? This is the bookmarklet for you. You’ll find it on your WordPress “New Post” page to the right of the post editor.

2. del.icio.us Bookmarklet

If you want to save a link to your del.icio.us account without adding yet another extension to your browser, check out the del.icio.us bookmarklets available here. There’s a Post to del.icio.us bookmarklet and one for viewing your favorites quickly.

3. Password Generator Bookmarklet

If you have trouble coming up with secure passwords all the time, save some time and energy by installing this bookmarklet. It combines the domain name of the site you need a password for with your “master password” so you only ever need to remember one password—minus the security concerns. You can get it here.

4. Microformats Bookmarklet

If your organization uses some sort of intranet project management that always has hCard or hCalendar (.vcf or .ics files) for download, or you frequent other sites that use these formats, the Microformats Bookmarklet will check through the page you’re on and find them for you. It makes keeping up with contacts and calendars easy. You can get it here.

5. Facebook Bookmarklet

If you’re an avid Facebook user and frequently share interesting Web sites using your Facebook account, this bookmarklet lets you do it even faster and without returning to the Facebook site itself. You can get it here.

6. Reddit Bookmarklet

The Reddit Bookmarklet makes it easier for redditors to not only submit interesting Web sites, but cast “like” or “dislike” votes for sites that have already been submitted. There’s also a “Serendipity” bookmarklet that’ll take you to a random site through Reddit. You can get it here.

7. Google Translate Bookmarklet

Constantly find yourself on pages written in French or Italian, but have no idea how to read any language but English? Your surfing habits may be baffling, but there’s something to make your life easier here.

8. FriendFeed Bookmarklet

Saving interesting tidbits to FriendFeed is easy and incredibly pleasant with this excellent bookmarklet. It can grab an image from the page you’re saving if you’re into visuals. Grab it here.

9. TweetBurner Bookmarklet

Twitter users will love this bookmarklet. It can be a pain in the backside to get a regular link converted into a shorter URL without a bookmarklet or a desktop client with the capability built in—but with this installed, it has never been easier. It’s on the front page to the left here.

10. ToRead Bookmarklet

Once you enter your email address on this bookmarklet’s homepage, you’ll be able to quickly send pages you wish to look at again and read in depth later on to your email account for easy access. Check it out here.

11. OnlyWire Bookmarklet

If you’re really into social bookmarking and have a hundred different bookmarklets cluttering your toolbar, this bookmarklet that supports many of the most popular sites may help you simplify things a bit and get pages bookmarked quicker. Get it here.

12. XRAY Bookmarklet

Web designers will find this bookmarklet useful. It’ll show you the box model for CSS elements on any page along with a whole lot of information about the element you’re looking at. Get it here.

13. Rollyo Bookmarklet

Sick of hunting and pecking through each site you visit to find a well-hidden search field? Rollyo lets you search any site you visit just by clicking the bookmarklet, and allows you to save frequently visited sites into a “searchroll” so you can search your favorites anywhere. Take a look at Rollyo here.

14. RatesFX Bookmarklet

Do you need to convert figures in one currency to another frequently? I’m always converting figures in US dollars to Australian (the results aren’t as pleasant as they once were!), so a bookmarklet like this is a huge timesaver. Try it out here.

15. Google Reader Bookmarklet

This Google Reader bookmarklet will help you subscribe to new blogs, or any site with an RSS feed, as you surf the web. Check it out here.

16. Newsgator Bookmarklet

Much like the Google Reader bookmarklet, the Newsgator bookmarklet will allow you to subscribe to RSS feeds under your Newsgator account. I love this because it means I can add a feed without opening NetNewsWire, which can take some time. If you’re using a Newsgator account in any compatible feed reader and getting sick of opening the app just to add a new feed, this is the solution for you. Find out how to install it here.

17. Layout Grid Bookmarklet

Another one for designers: this bookmarklet will overlay a layout grid on any Web site. Particularly useful if you’re developing your own and want to see how it’s matching up to your grid calculations in a browser without adding the grid as a background image. Check it out here.

18. View Passwords Bookmarklet

Whenever I login to GoDaddy I get paranoid that one small typo in my password will lock me out for the rest of the day—this has happened more times than I can count. Here’s a typo that soothes this paranoia and allows you to see your passwords as you type them. No more asterisks! Get it here (also offers a handy Remember Passwords bookmarklet that fixes those pesky sites that refuse to remember them for you).

19. Digg Submit Bookmarklet

If you’re a Digger, this bookmarklet might be useful for you—click it to start the submission process for the page you’re currently on. This is an unofficial bookmarklet. Get it here.

20. Spreeder Bookmarklet

Want to practice speed reading, but find the text that comes with your speed reading app incredibly boring? The Spreeder bookmarklet lets you paste a block of text into a dialogue box, which is then displayed to you in rapid-fire, word by word. Check it out here.
