Help not working after fresh installation of Racket 8.3

[Erich Rast]

On Linux Mint I installed Racket 8.3 as usual in local folder /home/nemo/racket. Now when I try to access the help in the browser (recent version of Firefox), any link I click results in an error message, for example: Could not display "/home/nemo/racket/doc/quick/-index.html" The location is not a folder.

The "-" in the path seems incorrect. In any case, I have full read and write permissions, the installation works otherwise, and the html documents exist and can be opened manually.

How do I fix this?

My first guess would be to use raco to rebuild the docs - but I can’t remember the exact command. It’s probably in raco pkg

Maybe: raco setup --doc-index

It's fixed. The problem was the configuration of Firefox's default applications. It was set to use Caja for opening files. I changed it  to use Firefox itself and it works now, although it opens every link in a new tab.
