Create Firefox Extension as per our requirement

Dear Freelancer, We want to create a Firefox extension for our staff to login and work on many of our websites and social media sites like facebook and twitter. We dont want to give them real usernames and passwords, as employees comes and go and we dont want to change real passwords all the times. So we came up with the idea of firefox extension, where once the extension is activated on our computers, and our staff comes to office in morning, they just login on the extension with their username and passwords. Each staff will have different jobs to do. So we will assign them the websites and will save their usernames and passwords, but staff will not know what it is. As it is saved in a database. Lets say john logins with his id and password and he is given facebook work, he will click on facebook url, facebook login page is opened and then there is a button called “fill data” when he clicks the button it will fill in the username and password like roboform. And just have to click login, and he is inside the facebook. This way we dont have to share the real facebook password with staff and still we can work around it. We have already created admin part of this with database in mysql, where we will create users with their profile, also we will create the URLs for work with real usernames and passwords and manage everything remotely. This extension needs to connect to our database and fetch the pre-defined details. Steps: 1) We have our own admin panal with mysql database online somewhere. 2) We will create users with their usernames and passwords. 3) We will create websites urls to work on with and save them with real usernames and passwords. 4) You create the extension. 5) We will install the extension on firefox browser on our computers. 6) Once extension is installed staff will login in the extension with our given username and passwords. 7) When staff is already logged in the extension he can see the available URLs to work on. 8) Staff clicks on the URL to work – E.g [login to view URL] 9) This will open the facebook login page on browser. 10) Now staff clicks on FILL DATA button. 11) This will fill facebook login id and password inthe fields like roboform. This login data is saved on our database, so you fetch them and fill in. 12) Staff clicks on login button and enters the facebook and start working. 13) As soon as staff logs in to extension you have to take their IP address, machine time, and all the websites he opens during their logged in time. So we can keep eye on what they are doing apart from work. 13) Also if someone is not logged in the extension but if extension is activated on browser please take the ip address and browsing history of that machine and enter it into the database. So we know what kind of use is going on our computers. I hope you have read all and understood the requirements. If you have any questions do not hesitate to send us an email. Thanks SteamLite
