I use and recommend DeArrow and SponsorBlock browser extensions. DeArrow makes video titles and thumbnails more truthful and frankly, more boring. It removes sensational thumbnails meant to entice and get you to click. I find myself watching less youtube because of it.

SponsorBlock blocks more than just ads-- it can block redundant previews/hooks that are meant to grab people's attention at the start of the video, as well as intermissions or intro animations. It can even help skip filler tangents and jokes. Overall, it saves me time.

Both extensions are from https://ajay.app/. Keep in mind there is a small learning curve and they take a little getting used to. Also YouTube just updated their site a few days ago which broke both extensions. So if you're thinking of trying, you might have to wait a few days until the extension maintainer gets them running again.
