As I was doing my fiddling today, I think I overloaded Firefox. It had 48 tabs on-screen, and there were others that I couldn’t see. Using CTRL-TAB to switch between them became impossible. Even viewing them (while selected) didn’t work – tabs at the end of the list weren’t on-screen, so you couldn’t see which tab was the current one! Thankfully CTRL-W works well to close a tab. Still, I’m down to a more mundane 12 now (really), and I have to manually select tabs. It’s like the whole index is just wacked. I’ll restart it in a bit.
