Firefox 70 looks HORRIBLE and is completely unusable on my Mac (latest Catalina).

WTH. Please see the screenshot. This is a fresh install of the latest Firefox (70) on the most current macOS (Catalina 10.15).

Hi greg21, It's probably a combination of the Theme that you are using and a change in the new version. According to the Release Notes: "Aliased theme properties have been removed, which may affect some themes" Also, see this article: Upcoming deprecations in Firefox 70 https://blog.mozilla.org/addons/2019/07/25/upcoming-deprecations-in-firefox-70/

Thanks! I found and blew away my settings area for Firefox -- it probably had some stale stuff in it from way back when.. All good now.
