Something has gone wrong with SeekingAlpha and Chrome. Build Version 62.0.3202.94 (Official Build) (64-bit), both at home and at a separate computer at work.

That's the bell icon. On the front page. At home it was also like that on other pages as well. At work, so far, only the front page.

Haven't seen the offending ad, this was https://seekingalpha.com/article/4126588-first-solar-inc-2017-q3-results-earnings-call-slides where it happened.

That blackrock ad, and previous blackrock ad have been the only offenders(the other one was running on every page months ago, May 23rd)
