This script arranges the video sources of certain sites, the same way
Additionally, it installs a dark theme and expands description texts per default.
Some of the supported sites are burdened insanely with animated advertisements, they were near unusable due to performance loss. Therefore, I added an IFRAME filter.
CTRL+click now opens the IFRAME target in a new browser tab. This is possibly helpful, if Firefox left the IFRAME blank.
