Today i want to ask to create from me addon for browsers :
Need as follow:
addon must have ability to keep checking website using API for incoming info(messages).
If message is received addon should show that by showing message and sound should be played which i will be able to setup in control panel.
Addons will have to keep data only till browser is opened, once browser is closed or pc is shut down session should timeout and user should log back in to allow addon to work.
Addon must check website in specified interval set by user or default.
Please check API at [url removed, login to view] as this is the target website.
