Video playing, ad that scrolls, two lines of a story, the bottom popping up with notifications every few minutes over the top of more scrolling ads.
Yay internet.
Edit: Oh wow! Did not expect so many responses. First let me say, thank you for taking the time to read and respond! To address the biggest response to use Firefox I actually have it on my phone it's just remembering to break the habit. This was more to show what an average user who just uses what they're used to experiences on mobile browsing.
Tbh when I got my current phone it gave me the option of installing a duckduckgo browser. Seems to work fine and gives you a 1 button burn option that clears out cookies etc.
Only thing I have noticed is fb doesn't let you log in but tbh that's only a good thing in my book.
