Firefox and IE and Chrome Addon

I want to only use a developer that has previously created add-ons, and I may need to verify this before accepting you as a bidder. My Add-on application must work the same for all browsers that accept add-ons and must work on Operating systems that can use those browsers. The application will require the user to login with his username and password. This is stored on an existing PHP database. The application will then show him a list of items that he is required to complete. Slightly more details will be given to the approved developer. The application will also show him new items as he receives them (your application will poll my db). The user can then remove these items one by one (I will explain to the approved bidder how we need to achieve this) ## Deliverables 1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. 2) Deliverables must be in ready-to-run condition, as follows? (depending on the nature? of the deliverables): a)? For web sites or? other server-side deliverables intended to only ever exist in one place in the Buyer's environment--Deliverables must be installed by the Seller in ready-to-run condition in the Buyer's environment. b) For all others including desktop software or software the buyer intends to distribute: A software? installation package that will install the software in ready-to-run condition on the platform(s) specified in this bid request. 3) All deliverables will be considered "work made for hire" under U.S. Copyright law. Buyer will receive exclusive and complete copyrights to all work purchased.
