No plugin. Let you send link directly to GMAIL in your browser.

" Gmail this "

Right-click on the above link and add it to your bookmarks.

This way, when you come across an interesting webpage, you can simply click on "Gmail this" in your bookmarks, and a pop-up window will appear — it's the GMAIL email composition window (of course, if you're not logged into GMAIL, you'll need to log in first). The subject will be the title of the webpage, and the content will be the link to the webpage.

I've tested it in both FIREFOX and IE, and it works in both. In short, it’s just SO convenient!
