[FEATURE] Allow executing bookmarklet on dragged link, not only current tab

[fernandeusto]

Hello,

First of all, thank you for this great extension — it really helps to make bookmarklets more accessible in Firefox.

Currently, the extension only executes the bookmarklet on the active tab/page when clicking the button. This works well in many cases, but it would be very useful to also support executing a bookmarklet on a specific link that is dragged onto the extension’s icon.

Instead of opening the link first and then running the bookmarklet, it would be much faster to simply drag the link from the page onto the extension icon, and have the bookmarklet run on that link’s URL directly.

This would greatly expand the flexibility of the extension and make it possible to apply bookmarklets not only to the current page but also to arbitrary links.

Would you consider adding support for this behavior in a future version?

Thanks again for your work on this project!
