Hello community. I need some help with my Sync account for Firefox. Recently my laptop got stolen and therefor I lost all my data. I setup sync on my old laptop and let it sync my settings, tabs, extensions etc.

But now when I try to log in on my new device it asks for my encryption key. I don't have that anymore. There is an option that says "I lost my old device" and when I click on it, I can see that in the settings screen behind it my settings and account are displayed but the "Next" button is grayed out. I really need my tabs back.
