You fill your phone with apps to make it work harder for you--but how about the computer you use every day at work?

Chrome extensions work to supercharge your go-to Google browser, enabling you to increase productivity, streamline your projects and safeguard your online security. The best part: none of them will cost you money.

Try introducing a few--or several--of these 10 add-ons to your Chrome browser. You'll quickly discover how essential they can be to your workday.

1. Email Hunter

Cut down the search time of sending cold emails with Email Hunter. This nifty little extension gives you a list of every email address associated with the website you are visiting.

2. Rescue Time

Keep tabs on on how you spend your days and get your productivity on track with Rescue Time. While you may not love seeing how many hours you've logged on Facebook each day, admitting you have a problem is the first step, right?

3. StayFocusd

The next step to fixing that Facebook/online shopping/gossip site reading time suck is to block it! StayFocusd steps in where your willpower leaves off by limiting the amount of time you spend online, or just on select websites.

4. Boomerang

Those emails you fire off late at night are bottom of the pile by the time everyone gets to work in the morning. Instead, schedule them to be sent at prime reading times with Boomerang, which also sends reminders to follow up on emails that have gone unanswered.

5. HTTPS Everywhere

Help prevent an unsecure website from compromising your personal information with HTTPS Everywhere, which automatically makes websites switch from HTTP to HTTPS (read: more secure) connection when supported.

6. Pocket

Block all of your industry, trends, research, and fun reading time into convenient blocks with Pocket, which aggregates everything you bookmark so you can read it on any connected device later.

7. OneTab

When you have so many tabs open that you can't even see the first letter of the website, it's time for a better solution. Use OneTab to convert all of your open tabs into a list, which not only make them easier to scroll through, but also speeds up your computer by reducing the CPU load.

8. Todoist

If you're anything like me, you live for checking items off to do lists. The Todoist extension takes the collaborative, multi-device cloud task manager and puts it all on your browser, and lets you add webpages as tasks with one click.

9. Hubspot

An extension of the amazing productivity tool Hubspot, Hubspot for Chrome adds a button to your browser that lets you track the times your audience is engaging with your emails or social media. This extension also lets you share content and track analytics directly through the browser.

10. Google Similar Pages

Research online more efficiently than ever with Google Similar Pages, which lets you preview--you guessed it--similar pages to the one you're looking at.
