This extension used to offer a feature that is very useful which I used to create nearly every shortcut link (since I develop web pages) — custom URLs for the website thumbnail; HOWEVER, after an update, the developers converted this feature into a SUBSCRIPTION–ONLY option, making a once–free option a paid–only option, rendering the extension almost useless to me unless I choose to become a victim of their extortion scheme.

This should never be allowed because there is no justification in charging monthly money for something that has ALREADY BEEN DEVELOPED and worked without needing any code updates, as it constitutes a BAIT–AND–SWITCH tactic which is illegal in most jurisdictions.

Sure, charge a monthly fee for hard cost items like online cloud storage, any–device settings synchronization, and image upload to their servers, but putting a custom URL to pull an image places ZERO financial burden on their company and they should be warned / removed from the Mozilla extension store for such tactics unless they RESTORE this previously extant app functionality.
