Tumblr/Xkit not functioning properly
This might not be an issue for Vivaldi but Xkit. Xkit is a chrome extension for Tumblr specifically, which makes Tumblr work more efficiently and gives one a number of brilliant fixes.
I use Tumblr Xkit regularly.
It works well on Chrome, but doesn't work on Vivaldi correctly. Is there something in the interface between the two? Is this an issue for Xkit or Vivaldi or both?
