I didn't notice the lights on thing until I saw someone else commenting on it, but I can't be arsed with the massive advert at the top which cover at least half the screen! I was brought up by my DM not to "be a victim of advertising" so I don't even know what is being advertised!
Until recently I had an ad blocker installed and then had to uninstall because it kept killing Chrome. It was only after that I noticed this annoying one at the top of the page and I assumed it must have always been there and I was only just seeing it for the first time because no ad blocker.
It is very intrusive. I can live with the ones down the side but this does seem to obscure some of the controls I want to see
