Konami Code isn't working on Firefox 59

[ptrcnull]

It tries to search "ba" in the quick search box, so event listener doesn't record it,

It definitely works for me... what's the "quick search box"? Is that like a find-in-page thing or a search engine thing? Is it an extension?

It's an embedded Firefox feature to quickly find a word in a page, looks like this now:

Is this only on Linux, or is it an about:config flag?

Moreover, what do you think I should do about it?
I could add an option to the Extras menu that triggers the same effect, but it seems like I probably can't prevent-- well, okay, if it's doing that because the key events aren't prevented, I could edit the Konami Code detector and make it prevent a and b if and only if the pattern has been typed up until that point.

But basically, how do I get to this feature for testing?

I think it's enabled by default on Firefox 59.0.2 (64bit) on Windows.

EDIT: It does work when I add e.preventDefault() on keycodes 66 and 65.

Okay, it's an option in about:preferences (Options), "Search for text when you start typing"
(and accessibility.typeaheadfind in about:config)

I'll work on this now

Done! And btw these shortcuts are interesting. I've sorta been switching to Firefox since chrome is being a huge memory hog (with lots of tabs open, I should say!), and since Google removed down/up arrow keys support for navigating Google results, this seems like it would be a useful way to navigate them (').
I installed an extension to add the arrow keys functionality back in chrome, but this is a more general feature... I look forward to trying it out.
