Using Fedora Linux, last I tried a switch to FF (less than 6 months ago) it was way slower than chrome. I actually like FF functionality more and would prefer to use it but my laptop runs significantly hotter when I run FF on it.

Just given its Fedora I would be a bit nervous to instantly assume full blame on Firefox, given the nature of the OS, but definitely give a try again!
I don't really have any issues with Fedora performance wise, is it widely perceived to not be performant? I have had much more issues with everything on Ubuntu than I ever had with Fedora. Maybe ricing with Gentoo could get me a bit further but given both Firefox and Chrome will basically use the same system libraries I don't see how it is fair to blame Fedora for the difference.
I've been running FF on Fedora for the last 14 months with no problems. I typically have 20-40 tabs open, but then again, I'm also using NoScript so maybe 10-20 of those tabs are not doing so much damage to my performance. (The ones that stick around, like 4 Gmail tabs, Slack, RSS reader, etc. are whitelisted)
Are you running Wayland? Make sure Firefox was running in Wayland mode. Fedora had a separate package for Wayland Firefox for some time, though it might be the default in 31. XWayland can result in a performance hit.

I am not using Wayland and I am running XFCE
This has been my experience across Linux distros and was also the case on my MacBook Pro. Whenever I mention my MacBook issues the down voters swarm despite the fact that there is an open bug regarding poor performance on certain MacBook configurations. And no the performance fix for Macs that came out a few months ago didn't resolve it.
Is it faster on Windows? This would be quite fascinating if it is the case - my experience with windows is that it is an all round slacker when it comes to performance.
I remember reading about an issue on some Linux systems, not sure if they fixed it, but do report these issues if you can.
Not sure how, it is not exactly a bug, just ... a thing.
