If you turn loose a completely untrained person to click yes/accept/download/OK/I agree on every type of user interface popup, particularly a person who has no ability to distinguish between a user interface question presented by the operating system itself and something inside of a browser window, that's what you'll get...
I’m aware, that’s exactly what my grandfathers (rest in peace grandpa, I miss you) IE window looked and felt like in the early 2010s!
I was recently doing some maintenance on my mom's iPhone SE and was quite shocked at how many random apps she had installed. Random forums, shopping apps, etc. Bespoke mobile app wrappers for simple web apps may be the new 'toolbar' or 'browser extension'
You can just say AI
I have a vivid memory of once looking over someone's shoulder in the IE days and being horrified to see toolbars taking up about 80% of the available screen real estate, leaving only maybe 150-200 pixels of vertical space for actual web browsing. I have no idea how they got anything done, and my guess was they never actually used any of the installed toolbars and just thought that was normal.
