Hello!
Can do this task very fast.
First of all - I'm full time freelance programmer with 10 years experience, working on local freelance sites (such as [login to view URL] and [login to view URL]). And I'm new on freelancer.com, so that's why I set low price for it.
About work: I have wide experience in writing on Javascript, including Chrome and FF extensions. Watched the video, want to disquss with you details and can start work right now.
Almost always online, waiting for your answer
Thank you.
