Everybody loves goo.gl to shorten long URLs. Did you know there's an Extension for that? If you add it, with one click, you can shorten your URL without copy and pasting and having to go to the site. Another great feature is the ability to make a QR code too!
Another great Extension is OneTab. Whenever you have a lot of tabs open, click OneTab, and it will convert all your tabs into a list. Whenever you need to access them, you can restore them individually or all at once. Another great feature is it saves 95% of memory because you have reduced the number of tabs open in Google Chrome.
