    Bug 1769572 - [devtools] The CONNECT method should no longer be sent on request resend. r=nchevobbe, a=RyanVM
    
    The CONNECT method sent on Edit & Resend of certain requests crashes firefox
    based on https://bugzilla.mozilla.org/show_bug.cgi?id=1769572#c2, Necko uses CONNECT in a special way, so lets restrict
    the devtools from selecting and sending it.
    
    The crash happens with both the current and new edit and resend panels, so this patch
    needs to be tested for both.
    
    Use the devtools.netmonitor.features.newEditAndResend and set it to true to enable the new edit and resend panel.
    
    Note: The new edit and resend panel is enabled by default in Nightly.
    
    See https://bugzilla.mozilla.org/show_bug.cgi?id=1769572#c0 for the STR for the current Edit and Resend panel
    See https://bugzilla.mozilla.org/show_bug.cgi?id=1769572#c7 for the STR for the new Edit and Resend
