icloud messing up desktop icons

3 problems to report:
1) Ever since I updated creative cloud a few weeks ago, now the dropbox desktop icons (for dropbox desktop app) have disappeared. And I went over it with dropbox and they instructed me to go to System settings on mac → general → Login Items & Extensions, and scroll all the way down to the “extensions” section and find where its says “creative cloud” and hit the circle i icon, and toggle on and off “file provider” then my dropbox desktop app sync icons come back. Dropback says creative cloud is notorious for hyjacking desktop icons. I must note this fix is temporary and resurfaces later. I’ve provided a screenshot below of what the dropbox desktop app sync icons look like. 
2) Ever since I updated creative cloud a few weeks ago, my external hard drives on the left hand panel are defaulting to the creative cloud app. 

3)the authenticator app on firefox. when im on firefox it asks me to type in a number but doesnt give me a box to type it in. but when I go to safari it shows me a number on screen and thats the number I choose on my autheticator. Can you look into the firefox issue?
