@burnout426 When I go to your link it still doesn't work. I have recorded a short clip of this issue.
While I was reading about standalone installation and went to opera://about for at do notes... I've got an update to the newest version of Opera FX, and the problem disappeared. Status bar is showing on every page now. I'm not really sure what was causing the problem or if has been fixed in last update, but I'm happy for it working now
Thanks for all the advices guys!
