I am a vim gremlin. I use qutebrowser, which is ultimately chromium-based, because I cannot find any reasonable way to do vim bindings for Firefox. Tridactyl, the most featureful and mature vim binding extension for Firefox, shits out if Firefox hasn't loaded a webpage.
Is there any Firefox fork that is keyboard driven like qutebrowser? I don't see how it could be accomplished without a fork or patchset, as the WebExtension API simply has too many restrictions for a proper input method.
If it were, there would be a functional Firefox alternative that I'm unaware of. You don't seem to know of one either. The moment such a fork exists I'll switch, but my wrists are too fucked up to use a mouse constantly.
Webkit implementation is unmaintained and insecure, developer recommends against it. The comic is about users or developers relying on buggy or otherwise bad behavior for bad reasons - ie, extension developers mad about Firefox switching to a far more secure framework for extensions when their own extension is totally possible to implement without being able to monitor all web activity without even notifying the user, because they got used to doing it a bad way that is no longer possible. That's not really comparable to Firefox just lacking an accessibility option.
Trust me, I miss using proper extensions and not just greasemonkey scripts, I've wanted such a fork for years, but the only other reasonable alternative is Vieb which is fucking Electron based.
