I addition to this thread, I want to ask, if one of the developers can create a plugin to manage preloading videos as default.
The problem: Firefox preloads all videos by default and if you have a lot of vidos on a page nothing will work. It would be great to have an option to set the preload option for Dokuwiki by default.
Here are some informatiosn to the problem: https://surfthedream.com.au/disable-preloading-on-html5-videos/
