I use Firefox as my default browser and absolutely adore adding any extension that sounds vaguely useful of interesting. While I was browsing, I came across one that allows you to highlight the text on the page you are reading by selecting it and pressing a letter on your keyboard. There are three different colours, and when you're done it lets you copy everything to your clipboard to paste into another application.

You can download it by going to https://addons.mozilla.org/extensions/?application=firefox/ and searching for "textmarker".

Amongst others, I also use the tabbrowser extension, since it will open any page that fire up a new window in a new tab instead, so I don't have ten browser windows cluttering up my taskbar after a browsing session.

Firefox is definitely my favorite browser amongst all of the ones I have tried sofar. If you're not familiar with it, you can check it out at http://www.mozilla.org/products/firefox/

Thanks for the links, Squirrel. I have recently started using Firefox and my Mac loves it.
