Chrome extension Morphine takes Benjamin Franklin's famous line that "time is money" very seriously. With Morphine, developed by 16-year-old Teddy Cross, you redeem blocks of idle browsing time for blocks of productive browsing. Browse work-related websites for 10 minutes, and accrue one minute of goofing-off time. You can tweak the numbers, but the principle stands: Morphine lets you save time--literally.

I kept the default time settings, so for every 10 minutes of non-blocked browsing, I gained one minute I could spend on blocked websites. Clicking the Morphine toolbar button shows the current balance, and offers several buttons you can click to redeem it (+1 to gain one minute of free time, +3 for three minutes, and so on).

Like WasteNoTime, the biggest problem facing Morphine is how easy it is to circumvent: Just right-click its toolbar button and select Disable. The only thing standing between you and procrastination is willpower.

Morphine can help bolster that willpower, but it can also end up as a distraction. Its concept is solid and interesting, and could work well as a system-wide utility that tracks all browsers and is more difficult to circumvent.

Note: The Download button takes you to the Chrome Web store, where you can install the latest version directly into your Chrome browser.
