People love Twitter, and they love Firefox, so it only seems natural that there would be quite a few tools to merge these two items.

Whether you want to have a full Twitter client inside of your browser, or just the ability to share parts of a site, a whole Web page or just the URL of the site you are reading, there is a tool for you. Take a look through these 20+ tools and there is sure to be something that appeals to you.

As with all Firefox tool lists, we do recommend you don’t install all of these unless you want your browser to slow down considerably.
