Hi there! Thank you for reaching out. I’d like to clarify that the "Some features may require payment" message is a standard notice from the Firefox store, not specifically from my add-on.

For just a one-time payment of $5, you can enjoy unlimited usage of the add-on. I truly appreciate your understanding, as I’m working to support myself through my passion for open-source projects (you can check out my work on GitHub). Every contribution helps, as open-source developers like me also need to eat! :)

If you have any further questions or feedback, feel free to let me know!
