That should work, but there was another thread that recommended this add on: https://addons.mozilla.org/ru/firefox.../status-4-evar/

That should be statuspanel (tag name) instead of #statusbar-display for the selector

@namespace url("http://www.mozilla.org/keymaster/gatekeeper/there.is.only.xul"); /* only needed once */

statuspanel[label^="Looking"] {display:none !important;}
statuspanel[label^="Connect"] {display:none !important;}
statuspanel[label^="Waiting"] {display:none !important;}
statuspanel[label^="Transfer"] {display:none !important;}

You can possibly use these selectors to be more precise:

statuspanel[type="overLink"] .statuspanel-label
statuspanel[type="status"] .statuspanel-label[value^="Looking"]
statuspanel[type="status"] .statuspanel-label[value^="Connect"]
statuspanel[type="status"] .statuspanel-label[value^="Waiting"]
statuspanel[type="status"] .statuspanel-label[value^="Transfer"]

• [/questions/969955] Disable status bar without add-on

thank you very much cor-el

I used the code you posted at 969955 page [ https://support.mozilla.org/en-US/questions/969955 ]

quite strangely I must disable/enable Adblock Plus after, but it works

@namespace url("http://www.mozilla.org/keymaster/gatekeeper/there.is.only.xul"); /* only needed once */

.statuspanel-label {background:#FF9!important;color:black!important;font-family:"DejaVu Sans Mono"}

statuspanel {display:none!important} statuspanel {max-width:90%!important}

statuspanel[type="overLink"] .statuspanel-label statuspanel[type="status"] .statuspanel-label[value^="Looking"] statuspanel[type="status"] .statuspanel-label[value^="Connect"] statuspanel[type="status"] .statuspanel-label[value^="Waiting"] statuspanel[type="status"] .statuspanel-label[value^="Transfer"]

Thanks guys Will try these over the weekend.
