program a simple data delivery browser extension

A browser extension to display the user's desired facts about visited websites live. The extension will also have the option to lead back to a website for more information on that information (website not included in this project). desired browsers: Google Chrome, Firefox, Windows Explorer, Apple Safari An example of this extension would be if you go to [login to view URL], a little bar at the top right will tell you if they sell Mountain Dew. The bar will say "Mt. Dew" and be displayed green for yes, red for no. If the user wants more information they can click the bar and it will open our website with information about this topic. On my end, I want the options to set variables to booleans and links to my website pages. I will be able to add these data points for any amount of website addresses for as many variables as I want. The users can choose which variables they want to show and which to hide via a small icon located on the browser top right bar. I will be able to choose which are shown and hidden by default. If this project is completed before December 14th, 2017 I will add a new project for the freelancer to include more options such as user preference profiles within the extension. This initial project can lead to higher paying projects. *
