I'd go 64GB if you actually keep 200+ tabs.

Probably not overkill if you really keep 200+ tabs open.

Firefox is a memory hog with that many tabs. Each tab eats a chunk, especially if they’re heavy sites like YouTube, Gmail, or Google Docs. 32GB will work, but you’ll start hitting swap and slowdowns when things pile up. 64GB gives you breathing room so the browser doesn’t choke.

That said, ask yourself: do you need all 200+ tabs? Firefox has built-in tab unloading, and you could use a session manager. But if you’re the kind of person who genuinely uses them and never closes anything, 64GB is the right call.

Better to have too much RAM than to fight the OOM killer every afternoon.
