some elements not picked up in Firefox

[toppits]

For example:
body#stylus-manage .entry .actions{display: none !important}

Doesn't work in FF, while working fine in chrome. What am i missing

Works for me in FF.
I guess there's a mistake in your @-moz-document (applies-to).

@-moz-document regexp("^\\w+-extension://[^/]+/manage.*") {
body#stylus-manage .entry .actions{display: none !important}
}
