Add-On Corrupted for Firefox

[IntrovertedAB]

When I try to add the extension from the Firefox extensions search page I get the following message: "Installation aborted because the add-on appears to be corrupt."

I am using Firefox 139.0 (64-bit)

Is there an analogue of this add-on? The author seems to have abandoned it. Had to install a chromoclone, it still works there. You just need to copy the links to the video for the player wholesale.
