There have been several highlighter extensions I have seen over the years for Firefox, however this one might be my favorite.  The ultra light-weight Highlights add-on for Firefox simply highlights selected text on web pages with a right-click of the mouse.

To highlight text on a web page, select the text, right-click (‘Ctrl+Click’, on Mac OS X) and select ‘Highlight’ menu from the popup.  The default yellow highlight color can easily be changed, by clicking the “Highlights” icon on the status bar, and choosing the color picker.  To remove the highlights, simply refresh the page.

No matter if you are doing research or you just like to highlight interesting points while you read, the Highlights extension is an excellent way to mark your spot on the Web.

You can think of it as an electronic bookmarker that services as a guide with you go back to that specific web page.  Another neat feature is it also automatically records and saves your highlighted info in a scrapbook for later.

Here are some of the ways you can use this handy extension:

• As a highlighter to help you mark material on a web site
• Save specific positions in a web page by marking it with the highlighter tool
• Use as a scrapbook to collect a lot of data from different pages or locations
• Organize your thoughts, but using different colors and styles for different occasions or tasks

So next time you have a research paper due, you need to compare prices, you need to collect various stats for your boss or you have a school project your working on, try working with the Wired-Marker.  This is thus far the king of the digital highlighters.
