My big concern is add-ons. The whole reason I use Firefox is the availability of add-ons such as NoScript and Cookie Culler. I'm guessing NoScript will work with Quantum, but Cookie Culler hasn't been updated since last year. Roomy Bookmarks is also a major quality-of-life factor; it allows me to have a well-stocked bookmarks bar. And it definitely won't work with Quantum. That alone will give me strong pause about updating.
