The 3 dot menu is way too wide due to signing into my Firefox sync account. It shows my account email address fully and therefore makes the context menu wider. I liked the normal Firefox context menu design that stays thin as well as not showing the email address of my Firefox account. Also, just as a side note I'd like to mention that the context menu in general is buggy in the nightly app. Aaaand just as I finished writing this the context menu changed back to how I guess it's supposed to be. BUT this is because it suddenly shows that my account is not signed in. But then when I click it, it shows that I am signed in and the context menu goes back to the wide state (so I guess I caught another bug as well, where it randomly says you're not signed in even if you are)
