Using Windows 11 and a recent version of Firefox, if I open a command prompt window and enter: C:\Users\Admin\Documents>"C:\Program Files\Mozilla Firefox Esr\firefox.exe" --help

I get nothing.

Can anyone explain why?

Is it possible to change Firefox so that it works without "| more"?

Note that the above was on my Windows 11 laptop, but I'm sending this from my Windows 7 desktop. None of the suggested topics were appropriate, so I selected the first one "Accessibility".

I know his sounds stupid, but I can't find the settings button on my browser. The browser is fully up to date (updating is automatic). I don't understand what the problem is. I ended up on this help screen from the settings listed in the My Account page. Is this the only one? Or is there another settings page & button somewhere else in the browser. Your advice and information will be appreciated. Thanx.

I don't know how this happened, But I have two different for Firefox settings under "General heading"- says "default search" start-page and heading "Search" - says Firefox is search. I did not think that could be? how do I resolve this issue? I would like to make Start-page my default search engine in both. It has been very confusing.
