Products making money from browser extensions aren't traditionally thought of as browser extensions. 1password, bitwarden, and others are a good example. These are password managers, but the most common way of using them is via an extension.

Thanks! That's exactly my point! Browser extensions are rarely an independent business model, they are usually connected with some bigger project / platform and the extension is just an additional thing.
