I switched to VimFx so I could get electrolysis working. I had to tweak scrolling speed quite drastically and and there are some behavioural differences which means I have to unlearn some muscle memory. However, with the classic theme restorer addon the UI is compressed enough that it doesn't bother me much and I can use the keyboard for almost everything.

I still wish I could have the command line back though. Annoyingly Firefox actually includes some sort of command line thing when I press :, but it seems to be only for web developers. I'd be happy if Mozilla provided a way to extend that so that it could be used for actual browsing...

I switched to VimFx recently for the same reason. Actually, the ":" shortcut for the GCLI command line is a VimFx shortcut, not a standard Firefox one. The GCLI can be customized. See for example:

https://developer.mozilla.org/en-US/docs/Tools/GCLI/Writing_...

I added a command to toggle a preference in about:config that I switch often. It is kind of a pain to write and debug commands for the GCLI though (compared to writing javascript mapping in Pentadactyl).

Thanks for that. Unfortunately the documentation neglects to even link to API documentation for the objects that get passed to the gcli functions or even mention their types, so I guess I'm supposed to use some sort of console with print debugging to figure out what I can do with them... too bad it seems Firefox' built-in browser console just shows up blank.

How do you make the tabs go away?

In Vimperator, :set toolbars=none will hide the tabs. If you mean the extra blank space at the top left by hidden tabs, then go to customize menu (:dialog customizetoolbar or burger menu next to address bar → customize) and enable Title Bar[1]. It will hide the extra space when use with toolbars=none.

Thanks! I've been wondering about that for some time.

When that day comes, move to Pale Moon
