I use FF on OpenBSD as my daily browser. I have at least three different profiles running simultaneously with multiple tabs open in each (though I don't go nuts with tabs like some do -- I never tend to have more than 10 or so open).

It does occasionally seem to get stuck in a state where it just starts chewing CPU cycles and RAM. I've seen this mostly with Google sites like gmail or docs, so I assume it's JS-related. But it's fairly rare, and seems to be improving with each release.

Did you try container tabs instead of profiles? Could save you a few coh cycles.

The gmail/gdocs slowdowns are being tracked and worked on. It's a problem when websites actively optimize for competitive products though.

The other problem with container tabs, which isn't really a Mozilla problem as much as a Google problem, is that if you have enough segregated google profiles going you seem to hit some google anti-abuse codepaths or aomething. I have 3 separate Google accounts separated with container tabs (on purpose, I know Google supports multiple accounts), and a separate regular browsing container, and occassionally just following a link from Gmail or hangouts where Google bounces you through their redirect hangs for 30 seconds or so. When it's doing that it generally does it consistently though.
