@esshor, there was a problem where the chrome extension didn't remember the lifetime license but that was fixed.
What made it an issue was that there was no license key, when the license was purchased through the chrome store.
Google decided not to do that anymore. Now those who want a license for chrome, get a license key like Firefox and Edge does.
You don't have to worry, just keep your proof of purchase stored somewhere if you intend to get the license.
