I'm curious about the difference between the two.

Proxy also seems to be affected. There is no problem if I do it the second time, but if I proxy it the first time and use it on another computer, I cannot connect because it is already connected. Is there a difference?

Hi,

All the browsers created with a aContext parameter set to NIL will use the global context and all of them will share the same settings, cache, etc.

Creating a browser with a new ICefRequestContext instance allows you to have an independent browser with different settings, cache, etc.

See the MDIBrowser demo :
https://github.com/salvadordf/CEF4Delphi/blob/be0efab35e624317514b6614f1771d7f4c446e8c/demos/Delphi_VCL/MDIBrowser/uChildForm.pas#L172

TempContext := TCefRequestContextRef.New('', '', '', False, False, True, nil);

TempContext := TCefRequestContextRef.New('', '', '', False, False, True, Chromium1.ReqContextHandler);

What's the difference?

The Handlers are used to expose Delphi events among other things.

Creating a TCefRequestContextRef instance with a Chromium1.ReqContextHandler means that the TChromiumCore instance will get TChromiumCore.OnRequestContextInitialized and TChromiumCore.OnGetResourceRequestHandler_ReqCtxHdlr events.
