Send URL to SMPlayer oleh Sondouk

Send URL to SMPlayer allows you to send the current tab URL to SMPlayer.
This extension is useful for users who frequently watch videos or listen to audio in their browser and want to easily open them in the SMPlayer media player with their preferred playback speed.
It is also useful for users who have installed SMPlayer in a non-standard location and need to set the path to the executable manually.

You can read the instructions page after the first extension install.
