Beautiful add-on, even better than google's original extension and certainly better than other arts and culture add-on. imho it'd be even better if it also worked on new windows. moreover it somehow breaks the tabliss add-on for new windows (moz-extension address of tabliss stays on the address bar)

Infinitely better than the other google arts and culture extension, but I wish it had the option to update the art every time I open a new tab instead of having to manually update it
