How can I add search/filer parameter to the end of about:config url? I have seen somewhere, but I forgot... I would like to add to bookmarks. For example, the browser.display.use_system_colors , because often switch true/false, and I hate retyping...

It was something similar like this: "about:config?" and yet there was also "#" and perhaps even("search" or "q" or "query" and "=").

Thanks!

Currently I cannot find a feature that has a filter like this on the desktop.

I did file a bug for an enhancement however: https://bugzilla.mozilla.org/show_bug.cgi?id=1074359
