Also breaking my experience and workflow!
Yes this is also a deal breaker for me. The Vivalidi Shortcuts overriding my webpage experience, especially in editing web applications is not working out very well. For example, CTRL+B is for BOLD on all the editors, but what happens is that, yes the word gets bolded, but then my bookmarks tab opens and its now disrupted my workflow. I guess its back to Chrome for now...
