Hi all. I just updated to processing 4.0b8 some weeks ago.

If I use _/help/find\_in\_reference_ or _/help/reference_ menu entries nothing happens. Nor firefox opens, nor window or tab in firefox opens. But if I exit PDE then a window or a tab opens with the instruction previously selected (for _find in reference_ menu entry) or just the reference index (for _reference_ menu entry). Need to say: I get an _unable to conect_ error since the server on port 8053 is not longer running, restarting processing gives the same error. Restarting firefox is how I can get the page even if PDE is not working! Of course, if I hit the reload button i get again the “unable to connect” error page.

Also I would like to know why a local server is launched for help when the usual _file:///_ method worked so well. I think this has been discussed somewhere, but has been unable to find about that.

Oh!! And just found something else. Just launched processing 3, it uses the _file:///_ method and help is opening after I exit PDE.

My system is fedora 36 with mate desktop environment.
