First of all, the activation worked, so no worry there.
After entering the license code, the browser (Firefox) created many tabs and kept doing so. I quickly closed the browser and reopened it, then I used ctrl+shift+t to restore the previous window, and I had 30-something tabs with moz-extension://41680aa6-1a71-404e-a279-24bcc6ec5c6f/help.html open confirming I was licensed.
However, when I clicked one of the tabs (most likely the one in which I had entered the key) it started spawning tabs again. Not sure which url that tab had.
Other things:
Before restoring my previous session, I checked the settings page and that one already confirmed that I had a valid license. So the session restore was not a required step.
