Recently, Google opened up its Chrome Extension Gallery for use with the Google Chrome Browser. The beta channel and dev channel versions of Chrome have had extension support for a while, but with the opening of Google’s official gallery, many new extensions have been made public. In my opinion, extensions are the main thing Chrome has been missing in comparison to Firefox so far. Here is a list of several extensions I recommend. These extensions get Chrome very close to feature parity with Firefox for my uses, with the one glaring exception of a replacement for Firefox’s NoScript.

AdThwart – AdThwart is an ad blocker that ports parts of Adblock Plus from Firefox to Chrome. It’s still early in its development so it still doesn’t compare to Adblock Plus, but so far this seems to be the ad-blocking system with the most potential on Chrome.

Bit.ly Shorten Url – If you use Twitter much, you’re probably familiar with URL shorteners like bit.ly. This extension puts a button in your address bar that shortens the current page’s URL with bit.ly. Simple and effective.

Chromed Bird – A simple Twitter client that sits in the toolbar. It updates you with new tweets and allows you to tweet without going to the Twitter website.

ChromeMilk – A great client for Remember the Milk, the online to-do list software, that sits in the toolbar.

One Number – Addicted to Google? This extension keeps you up to date on GMail, Google Wave, Google Reader and Google Voice.

XMarks for Chrome – Chrome does incorporate Google Bookmarks, but I find XMarks gives much more control on what is synced and where, plus it works on more browsers. Just like XMarks’ extension on other browsers, this one syncs your bookmarks online for free and lets you choose which bookmarks are which computers.

youTagger and YouTube HTML5-ifier – Don’t like Flash, but like YouTube? No problem! These extensions replace the YouTube Flash Player with YouTube’s new HTML5-based player. The HTML5 player improves performance of YouTube videos and makes them less likely to crash the browser. I’m currently listing both extensions because each has an issue that could bug you. youTagger works everywhere but loads the low quality version of the video. YouTube HTML5-ifier loads the highest quality version of the video, but only works when directly on a YouTube video page, not on embedded YouTube videos or on YouTube User Channels.

Hopefully, proper high-granularity content blocking will be implemented soon so that real equivalents to Adblock Plus and NoScript on Firefox become possible.
