Create plugins for chrome, firefox then list them in the stores & directories to get downloads.

Please read description I will not respond to canned responses. Hi. I have developed a web service to provide synonym and dictionary lookup for words. I want plugins for firefox and chrome. The plugin should be simple. The user can highlight a word, then either right click it and activate the plugin to show synonyms or click a small icon on the browser. In addition, I would like to have the icon button pull up a search box (if nothing is highlighted) where they can enter the word and do a synonym lookup on my site. What I want is a lightbox to pop over and show results from my site. I already have an api that shows results in JSON. We can work with my app coder to make it seamless. The app itself is fairly simple but I'm looking for someone experience in getting the add-ins added to the downloads and extensions of the following sites. [login to view URL] [login to view URL] I hope to get the addins/extensions/plugins on there with 10 or so downloads each by the end of the week. Please detail your experience with chrome and firefox and if you have sample plugins or extensions you've coded pls link to them. The budget is small, $100 or less and will work by hour. For someone who knows what they are doing I'm guess it is a 5 to 10 hour job.
