Edit: I have installed the update, but the issue persists.

It does indeed cause channel links to go to the videos tab instead of the home tab, so in that sense it works. However, it blocks using Cmd-click to open the page in a new tab. It always opens in the same tab, even when I'm holding the Cmd button.

This addon does exactly what it says & I want.

I don't even use Firefox, but this exactly what I was looking for!

Just what I was looking for!
