I had some issues adapting to some security features in OpenBSD, for example, to have videoconferences (let’s meet). Another interesting problem I had was that I could not upload files from firefox.

To fix that, all I had to do was enter on this “page”: about:config and change this setting to the specified path that I wanted dom.input.fallbackUploadDir.

There you go, now you can upload files from this directory on your firefox.
