Fórum podpory Firefox

I have uploaded a pic of this IceDragon Firefox treatment, I want Highlights to start open and the word and menu access area there not be present, also I want the Open Menu dots on the right to not be there, also the superfluous gear still further on the right I want gone, thanks.

Yesterday, 2/4/23, all of a sudden Firefox won't connect to any websites. I push a shortcut button, or type in a website and the address shows in the address bar and in the tab the dot bounces left and right showing it's trying to connect but it never connects. I have no idea what caused it. There were no updates of windows or anything else. Ice Dragon web browser, based on firefox, MS edge, chrome, Brave, all work. Anyone have any ideas where to start troubleshooting? Thanks, Darren
