In a little more detail...

Hey up, if you want to add a bookmarking button - addthis do a generic one which works with seamonkey here:

it means you can add stuff to social networks without the need for a download as it opens up a pop up box on clicking - very handy!

my firefox isn't working on my unbuntu operating system so I found this browser in their software center that installed at the click of a button, where as other browser expect me to know what to do with those tar files and stuff - I like plug and play, and this one does that.
