> By having a review process for extensions just a few suffer (the extension developers) and many (the users) benefit, because they can trust the browser.
The users will also suffer if there are less extensions available because most developers of $small_hobby_project don't want to go through an approval process every time they try to update their extension (and you would need to check every update, or the whole ordeal is pointless).
They'll especially suffer if, typical for Google, the extension review team is horrible and understaffed. Google can't even get paid support right, what makes you think they'd be quick and orderly about approving free browser extensions.
