MacBook Pro High Sierra. If I click a news story link in facebook, it opens in a new tab and I cannot scroll on the new page with mouse wheel, trackpad, or arrow keys. I can only move the page by clicking and dragging the scroll bar. Reloading the page does not fix it. This happens at least 90% of the time but not every time.
If I hold down the command key and click, the link opens in a new tab and I can scroll normally with trackpad and arrow keys.
