Today's web browsers are modern marvels. Most of us live inside of our web browsers, and can't fathom the world of computers before the browser's inception. Given their frequently evolving capabilities, they present an almost limitless world. The true revolution, however, came with the advent of browser extensions- tiny pieces of software design to enhance browsers' functionality- but browsers can become tremendous resource hogs when the installed extensions start to add up. Mozilla Firefox and Google Chrome, arguably the world's two most advanced browsers, are especially guilty of this. To combat their hungry ways, use bookmarklets instead of extensions.
I've packaged the current crop of bookmarklets that I use most regularly. Click here to download them as an .html file, which will open in your default browser. From there, simply drag the bookmarklets you'd like into your bookmarks bar, and voila! You're on your way to speedier browsing. If you're looking for more bookmarklets, Marklets is a fantastic resource.
Tip: If you're using Firefox, right-click in the tab area to show the bookmarks bar. If you're using Chrome, simply press ctrl+shift+B.
