Experienced Javascript developer needed for Open-Source Firefox extension features

Hello, we are a software development company with a bookmark manager service called WebCull. We are looking to hire someone with significant experience in Javascript and preferably with experience developing Firefox/Chrome extensions. We currently have a working Chrome and Firefox extension that we want to fix up with small changes. The project is on a public github repository so you will be able to advance your own personal github account by contributing to this open source project. If we like you and like your work we will have constant flow of open source work for you. This will start as contract work but could evolve into a monthly pay for part time and eventually maybe full time work. Most of your work with us will involve building on open source and free software. We see this as a big plus and hope you do as well by keeping it in mind when deciding how much you want to charge us. The budget is $50 USD List of tasks: (the attached file is a copy) [login to view URL] Link to the github project you will work on: [login to view URL]
