Windows 7 Tip: 
The twitterbar extension allows you to post to twitter directly from the firefox addressbar. A small unobtrusive grey icon sits to the right of your addressbar, clicking on it will post your tweet, hovering over the icon will tell you how many characters you have left.
Twitterbar also supports URL only tweets, simply click the icon without changing the addressbar text, the resulting tweet will automatically prepend “Currently Browsing: ” to the URL.
download Twitterbar from here.
