The back going back an extra page feels like a bug that has to get fixed. I usually control+click links to open in a new tab (maybe not exactly what you want, but hopefully helps)
I can't figure out for the life of me how to get rid of this "ghost" taskbar under the real taskbar. It looks like it has a safari logo on it - and I've never installed safari in my life.
Lenovo machine if that helps.
Edit: apparently it doesn't show up in windows snippets, attached a photo from my phone
