Been a long term Konquefox user, even though I'm on Windows. The Up button is a surprisingly useful addition regardless of what operating system you're on, and once you start using it, you'll wonder how you ever managed without.

It's a shame that the clear search bar button is gone, and that clear URL button doesn't work like it did previously, but it's obvious that this is due to WebExtension limitations, not the fault of the author.

Thank you so much for bringing it back!
