Here’s a list of the most essential extensions. If you don’t have these, God help you survive the internet age.

1) RSS Subscription Extension (by Google)

Whenever you see visit a website that has an RSS subscription option, you’ll see a feed icon in the address bar. Click it, and choose one of the feeds. It’ll open up in Google Reader directly (or whatever feed reader you specify). You can then choose to subscribe if you like.

2) Google Dictionary (by Google)

Are you one of those who keeps doing a “define:<whatever word>” search just to check its meaning? This this addon is for you. Double click a word (or ctrl+double click) to check its meaning. Plus you can type in a word to check its meaning too.

3) Proxy Switchy

Do you keep changing proxies? Whether it be for anonymous browsing, or accessing internet through a gateway at your organization. This extension gives you the ability to switch between proxies quickly. Plus, you can define wildcards and regular expressions for different proxies (like, use the China proxy is the URL has the term “hack” )

4) Google Mail Checker

This addon lets you see the number of unread mails in your GMail inbox. It however does expect that you’ll stay signed in all day long.

5) Chrowety

This is possibly the best twitter app/extension/addon I’ve seen. It is probably even the prettiest of them all too. It shows images (from twitpic, yfrog, etc) within itself. Amazing extension.

6) SpeedDial

Replace the default “new tab” page with a speed dial page. This one just might get you to type a lot less.

7) YouTube Converter/Downloader

Get links to the video files for every video you watch. Integrates perfectly with the new layout of YouTube.

That wraps up the 7 extensions you MUST have. Or else the devil will eat you.

Anyway, got any extensions that you just can’t live without? Let me know!
