Earlier quoted context omitted.
Could you be more specific? I don't believe this is a known issue. If you're experiencing this behavior, you may want to report it: https://github.com/philc/vimium/issues Personally, I'm running Firefox 55.0.3 with `vimium-ff` 1.6.0 (current build on addons.mozilla.org), and the `t` keybinding opens new tabs just like `Ctrl-t`. Command repetition also works (eg, `5t`).
Sorry, new tabs from links in background, using 'F'. Or at least with yesterday's version on ff58.0a1

I'm not familiar with their release cycle, so I don't know when it'll hit AMO.
