+We have dropped the `screenshot_enricher` module because a new `antibot_extractor_enricher` (see below) module replaces its functionality more robustly and with less dependency hassle on geckodriver/firefox. You will need to remove it from your configuration file, otherwise you will see an error like:

 See all available Dropins in [the source code](https://github.com/bellingcat/auto-archiver/tree/main/src/auto_archiver/modules/antibot_extractor_enricher/dropins). Usually each Dropin needs its own authentication settings, similarly to the VkDropin.
