Over the past iterations of Firefox (mobile), especially since they launched their new UI, I've noticed the performance of features such as CSS animations, etc. have particularly degraded. I have two versions on my Moto X4, Firefox 68 and the new Firefox 92. I use both to test some of the web apps I develop and to my surprise the older version of Firefox performs much better! There's a noticeable jank on the web app (transitions, animations, etc.) on the newer version. The browser itself is much slower than the older Firefox 68. Frankly I don't see any performance improvement.
