Theme doesn't stretch fully for 2560x1440, much less 4K. :(

This is awesome. I recently got Really into the renaissance, And this is perfect. It's the renaissance & Firefox, My favorite Web browser & my favorite era, A perfect combination! Thank you for making this beautiful theme! And I hope that more 5 star ratings are given out! This truly makes Firefox a better place.

Excellent theme; been my staple go-to for years. Unfortunately, as of buying 28" 4K monitors, it doesn't seem to extend all the way to the left. Keeping it anyway, but a little surprised.

Very pleasant theme.
