Works great, congrats!!
I'm using this, and another one (telegran web in thunddebird) , Can you create one another for the icloud.com website (please)

Thank you very much for your kind words and using my addons :-D
For your question, I cannot develop an addon for icloud.com currently, but I have an alternative. You may use the "Open Tab" addon by Toshi available here: https://addons.thunderbird.net/thunderbird/addon/open-tab/. Thanks to that, you can right-click any hyperlink and open them in a new Thunderbird tab. I think it is one of the most underrated addons for Thunderbird!
