VimFx (and Vimium for Chrome -- XUL deprecation and the loss of Pentadactyl migth be what finally pushes to switch from Firefox to Chromium) are nice addons but feature wise they do only a small subset of what Vimperator/Pentadactyl do. I use Pentadactyl and I get a lot of use out of writing my own plugins, using autocommands to trigger different actions on different pages, using quickmarks, and using ":js" on the command line to debug javascript code.

I plan to use VimFx/Vimium in the future though because those keyboard patterns are ingrained in me now. Pentadactyl development has dried up over the last few years and it seems unlikely that such a huge change as XUL deprecation will be addressed. The developers have been asked about this several times through different media and not responded. I'm not sure about Vimperator. The developers are still active but porting is a lot of work and currently all of the necessary API's do not exist. Hopefully, I can cobble together something resembling Pentadactyl/Vimperator by using a few other extensions in addition to VimFx/Vimium.
