If you're using Google Chrome, and you're running the developer version that allows extensions to be installed, you can now install TwitterBar for Google Chrome.

After you've installed it, just click on the Twitter icon in the toolbar bar, type your message, and press Enter to post your message to Twitter. (You'll have to authorize TwitterBar the first time you tweet, but it only takes a second.)

If your message gets too long (Twitter only allows 140 characters), the happy blue Twitter bird will turn into an angry red Twitter cardinal.

Let me know what you think; I tried to keep as much of the functionality from the Firefox version as possible.

When Google released a document today showing the design process for Google Chrome extensions, I thought it would be fitting to have one of the first third-party extensions for Chrome address a major shortcoming of one of Google's other products. With that thought, I give you:

Install TubeStop for Google Chrome

What is TubeStop? It's an add-on that stops YouTube videos from autoplaying, whether you're on YouTube.com or anywhere else on the Web. It was originally written as a Firefox add-on.

(In order to try it out, you need to be running the developer version of Chrome, and you may need to invoke it with the "--enable-extensions" flag.)

To install TubeStop, just download the tubestop.crx file linked above and drag it into Chrome. After Chrome finishes animating a download icon, TubeStop is installed. You don't even need to restart the browser; you are now free to browse the Web without the imminent threat of YouTube autoplay.
