fire fox android has been ruined

the app just asked me if i my experience was good and this is where the link brought me. The firefox mobile app on android is performing teribly over last few updates. websites take 1000x times longer to load some elements. it feels like the cache gets full after loading 10 images. youtube videos take nearly 30 seconds to load on gigabit internet. marketplaces just wont load images. it gets stuck buffereing images and videos. the easiest fix is to switch browsers which completely eliminates issues. this is happening on multiple android devices. either the code for this app is ruined or compromized. the problem is not on my linux or mac devices. I really have loved firefox up to this point, and its sad that after 1 month of questionable management the browser is starting to break down. i am now forced to switch just so i can use the internet. also side not if there was ever a way to get themes on mobile browser that would be nice.
