Steps to reproduce:
Try to use vimium on this website
It should work without issue.
Orion and macOS:
Also somehow does not work on youtube.com I checked all necessary settings including compatibility mode, and whether the extension is enabled and the disabled websites list, and I found nothing.
Wrong website? I think there needs to be a check on the complex code regarding which website you are on… also, command+[ does not work in this instance, but I have no way of reproducing it. So there must be some minor code issue.
It appears it now works. It should be marked as done as it was fixed somehow in Orion 109.1
