Description
Describe the bug
When using vertical tabs on Firefox J goes to the previous tab which is above the current and K goes to the next which is below. This is opposite to how it would work in vim.
Suggestion
A toggle button to swap J and K would probably be the best solution.

Research direction
Start by tracing Vimium's existing J/K tab-navigation behavior and the options UI used for keyboard settings. Determine how the Firefox vertical-tab layout affects the current ordering, then verify that the proposed toggle consistently swaps the commands and that the setting is reflected in the extension's controls.
