This project should be pretty simple for someone who has already implement similar projects (Firefox add on that change the proxy settings).
We need a browser extension for Firefox (latest version) that allows the user to sign up for our service (link to a web page) or login (using a username and pass) if the user is existing. After the successful login (API call into our system) a list of location will be loaded (also received from our API) and the user will be able to click on a location and a proxy from that location is set as active in the browser.
We have already have the Chrome extension (see it here: [url removed, login to view]) and several developers here on Freelancer try to convert it for Firefox. They did not succeed because is not that simple. The proxy implementation is different in Firefox. So please keep this in mind and only bid if you can deliver the project.
We are looking for developers with experience in building browser extensions (if you can show your work in the bid – we will review it) that are able to deliver this project in time.
We are looking forward for your bids.
