>>The “back button” does not highlight or function on FR.
I’ve noticed that too. It’s not just FR. Seems like you have to let the page fully load before clicking article links.
Even then, occasionally the back button will grey out.
The back button works fine for me on FR. Perhaps it has something to do with the way you have your system set up. I also love having the tabs on top of the header, where there was wasted space. It gives me more screen space to view. Faster? Yes! I’m likin’ this.
