Hello!
I recently wrote an open-source Firefox add-on that loads Wikipedia preview popups on iNaturalist. Basically, a Wiki icon appears next to every taxon link, and when you mouse over that icon, a popup preview from the Wikipedia article appears. It first checks English Wikipedia, then Wikidata, then finally Wikispecies if neither of the former have an entry for the taxon in question. I wrote this to make it easier for me to identify which taxa on Wikipedia are in need of images, but it’s also just a nice way to quickly learn about a taxon and see the link to Wikipedia right away.
It’s on the Firefox add-on store here, and the source code is here on Github.
I would publish it for Chrome too, but you have to pay $5 to register as a developer there.
