Need a UK based experienced programmer who can develop a firefox extension for us.
This extension, when active, will put a grey filter over 'sponsored' products on Amazon - see the attached file. The extension will need to work on the whole Amazon page (not just what is in view) - as then when we are scrolling down the page - those that are not on screen that are sponsored products will also be impacted by the filter.
Assume that all products on the Amazon page have their own container, when applied, any that are 'sponsored' will have this filter applied. This filter is a grey overlay (which is slightly transparent so we can still see the products below)
