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

Ah, cool. Yes, known bug. Reported fixed yesterday (though I've not tried it myself).

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

Vimium can open a tab as long as you're in a web tab, just not a system tab like about:newtab. Actually has that same problem in Chrome.

Wait, really? The plugin page even uses 5t as an example of command repetition. Might not make the switch if that's the case.
