agreed - the contrast is so low that I double checked if my content blocker was removing some cookie modal while leaving an opaque gray backdrop. Then I focused on a different window and then an opaque gray backdrop appeared, for reasons I can't imagine, with a message saying "Click to focus page". Not the best introduction for such an everyday tool
I also had to check if my adblocker was blocking something extra - this site is definitely a unique experience when it comes to using and navigating it.
