Per my rating, I "loved it". Unfortunately, I no longer love it. It seems to be interfering with Hulu and Amazon Video services. When I could no longer watch videos in either of those services without switching to FireFox, I eventually disabled this extension and my problems were solved.
I hate to remove this extension as it makes opening links in new tabs so much faster, but sadly I must. Honestly this should be Chrome's default behavior, or at least there should be an option for it. Perhaps I should just switch back to FireFox, which is once again a decent alternative.
This WAS a great extension. It is no longer working. As the last update was nearly 5 years ago, I assume it's abandonware.
Very simple, absolutely no setup needed to disable the "close tab with middle click" functionality.
