After the update on the 14th, dark mode has gained weird stylistic choices that I cannot find a way to alter: namely, when closing a new tab, a white box with black font appears -as opposed to the previous darker toned grey/purple with white font. However as of writing this post, I notice that dark mode is not working on this webpage. Seeing as I have an extension enabled in addition to the basic dark mode selection in Firefox settings, I can only imagine that something was broken in the update. Please advise, the change is jarring.
