We just updated to 0.9.0. Noticing that if a user goes into their Settings on Firefox, the hamburger button shows up on the right, to the right of the sidebar widget but is overridden by the widget so on our side where the sidebar shows an ad, the profile settings go to the ad page rather than to the actual settings.
Tried the same thing on MS Edge and the settings button works but the settings menu displays off the left side of the screen and cannot be seen or used.
On Chrome it works but doesn't look natural, but seems completely functional. Users not on Chrome would have no way to know that there are settings at all as nothing indicating that settings exist ever appear for them (in my testing.)
