While browsing the internet each page will be searched for stock ticker symbols. When symbols are found a small bar will be displayed near the top of the page with the stock price and other metrics (such as volume) that have been configured to be displayed. The ticker symbol itself in the bar is a drop down menu with links to various charts and graphs.
This is not designed to provide real time data, rather to display important (to you) metrics while researching potential stocks to own.
This extension is still in the development stage, please provide feedback on what works well, what does not, and what should be added. Use Shift-Alt-O (windows), Shift-Cmd-O (mac) to force open and close the bar.
