Idk how you use Firefox wrong but anon here is doing it. Got mine loaded with add-ons n shit never had an issue in years. Imagine actually using brave.
The problem is chromium dominance (edge and chrome mostly) as it makes other browsers vulnerable to the noncompetitive web standard changes that google likes.
I think there is likely to still be just as large of a personal variance in the rate that lisdexamphetamine is cleaved into the active metabolite, so the same problem arises.
I think anything that delays the active metabolite from taking effect technically dampens the addictive potential; the longer the better. I also think it’s unlikely to really solve the problem though tbh. People can still tell what’s causing how they feel when they start a new medication.
