Hello, I'm using a docker container to access an old dell r710 with iDRAC 6 and I'm stuck configuring some parameters because I can't use the shortcut ctrl+n because firefox opens a new window. Reading this https://support.mozilla.org/bm/questions/1381773 I assume that I can disable ctrl+n in firefox using autoconfig.js (/etc/firefox/defaults/pref/autoconfig.js) and firefox.cfg (/etc/firefox/firefox.cfg) but I don't know what should I write on these config files. Can someone give me a hand? Thank you in advance!
