I usually don't use picture themes as they stand out too much but this one is well done. Also really good cutting of the image - I couldn't tell until I looked looked at the jpeg. The theme works best on a 720p sized display because on 1080p, the other half of the tab bar doesn't have anything (black filler). My only gripe is that the Firefox Home (new tab/ new window) page has a white background, and it's really bright when I'm in dark mode. Nonetheless, the foxes are really cute and it makes me proud to be a Firefox user!
