Bot/automatic uploader for secured website

A more detailed description after still not having found the solution!! At this moment we use Turbolister to publish our auctions on Ebay. In the netherlands we also have a marketplace called Marktplaats.nl. [login to view URL] is a daughter company of ebay.com. [login to view URL] does not allow the use of an automatic uploader, they are in an secure environment. This means you have to manually process the adds. The largest problem is that [login to view URL] will not allow anything but manual processing of the adds so this bot should post with a pause to trick the website. Also there probably is a problem with uploading the pictures (info from another freelancer, javascript instead of html??). A couple of years ago we hired someone to make an automatic uploader on [login to view URL] which worked through an add-on/plugin on Firefox. This way we surpassed the security of Marktplaats.nl. Unfortunately this doesnt’t work anymore. We now synchronize Turbo lister with ebay, then use this data to export to excel and upload the csv-file to Markplaats.nl. That last link is now missing. We also had news a couple of days ago that Firefox will not allow anymore plugins from the beginning of 2016. We have had contact with a few people now and the problem has not been fixed yet. Largest issues: - Security of [login to view URL]; - Automatic uploader/bot which seems like manual work/human hands; - Pictures in correct form; - Future updates of the website which more and more can be compared to eBay. As mentioned before again posted because the problem seems to be to complex.
