Crossrider Extensions shutting down

Right, as we observed back in January, Crossrider has moved away from its extensions platform, and now (the 26th of September, 2016) I received the following termination notice from them:

Dear Partners, 

All good things must come to an end eventually and, regretfully, so does the Crossrider Extensions Development Platform. After several years of collaborating with you, we have decided to terminate the service. 

Please be advised that termination of the service is effective immediately upon publication or otherwise receipt of this notice. For your ease, Crossrider Extensions Development Platform will remain available for another 30 days from 27.09.2016 for you to download your project code / source code / extensions, following which your data will be lost. 

See below an instruction note on how to download the project code from our server for your easy reference; but kindly note that Crossrider is not able to provide further assistance. We would like to thank you for all your support and trust throughout the years and hope we can have the opportunity to collaborate again in the future. Best, Crossrider Team

So you can still download your source code in the remaining 30 days, and with careful review you can try to adapt it to creating your own native extensions for your preferred browsers.

I had good results moving to WebExtensions for Firefox and Chrome, some concepts are different from Crossrider's API, but still recognizable. I have no recent experience with Safari or Edge, so can't recommend much. Feel free to add your comments.

I'll say it again — I really enjoyed working with Safari's support team, so I wish those guys all the best, they'll do well in any company. It was a good time working with Crossrider, but I am glad that the browsers are getting their stuff together in offering easier development routes.
