Unless it is a top-10 app, it is a no go. The top applications have millions of users.

A browser is my everything app. It is the most security essential tool I use daily, which requires vigilance in how I extend it. More users is a crappy proxy for how likely a developer can sneak through an insidious change.

I understand being cautious, but this extension is featured in the chrome store and has quite a few users and only requests access to youtube sites.

Not exactly fly-by-night...
