You can stick to Firefox 52 ESR until June 26, 2018, if you want. Mozilla is still working on a more powerful keyboard extension API for WebExtensions and I imagine some extension will be leveraging this at that point.

No, it won't be as powerful as Vimperator, but should be a good bit more powerful than for example Vimium.

The Tridactyl project is working on that - Mozilla hasn't shown too much interest so far unfortunately, despite code being there: https://bugzilla.mozilla.org/show_bug.cgi?id=1215061

The aspiration is to get it in for FF58. I suspect progress will improve once 57 is out of the door - I think Mozillians are pretty busy right now.

Congratulations on releasing v1, by the way.

Out of curiosity, what addons were you missing? Anything other than NoScript/uMatrix?

When I last tried, the adblocker wasn't as good as ublock. If I were to switch now, I would miss easy access to my passwords, referrer control, zotero, and RES (a bit, a userscript would do).

Some of the adblock issue is possibly an engine problem (there's some pre-script hooks that Webkit-forks don't support).

qutebrowser's adblock could definitely be better, right now it's really only a host blacklist: https://github.com/qutebrowser/qutebrowser/issues/29

Password autofill is something I want to take care once there's a plugin API, but there are ways to make it work (the password_fill userscript, autotyping in KeePass*).

Referrer control unfortunately isn't possible with QtWebEngine's API for now...

Zotero won't be possible, but I guess that won't exist any longer with WebExtensions either?

And Greasemonkey support is on its way: https://github.com/qutebrowser/qutebrowser/pull/3040

The zotero main program is now a standalone thing, but there's a webextension that lets you add things to your library. Looking into it, it seems you can get a rudimentary experience with a bookmarklet/jseval:

I'm glad that Greasemonkey support is coming, though. Will the GM scripts run in the same JS scope as page scripts?

Webkit forks also render text slightly worse for HiDPI screens and don't seem to support CSS `hyphens: auto`. Which is annoying because I really like justified text.

I use pinboard.in so is there a method to run bookmarklets to bookmark pages?

There's the :jseval command which would probably work, or you could write a userscript: https://github.com/qutebrowser/qutebrowser/blob/master/doc/u...
