So go to the website and use it. Many of us simply find it as a way for more propaganda to be fed to us unasked-for when we open up a new tab (at least, until we remember to turn it off).
In fact internally it's still packaged as an add-on that is installed on first run. Unbundling it would be super easy.
The product belongs to Mozilla, so I don't see why they shouldn't integrate it.
as with many things though it should be consent based and opt in; they can have a big button "add pocket to your firefox" and those who want it can opt in and everyone else won't have to go through the rigamarole of finding all the settings (strewn about in various locations including about:config) to disable it
That sounds far too civil and reasonable.
Because it bloats up the browser.
That said I find the articles they recommend interesting (and to steal my time ...).
