Firefox comes preinstalled with Kubuntu but I can't run it with my processor

I just bought a new pc that has an AMD Ryzen R9-7900X cpu. Apparently there is some kind of bug in Firefox that makes this particular cpu overload until it gets too hot and freezes, forcing me to restart the computer. I found this information by doing a web search, and it seems this bug is at least a year old or more. Is this something that is just not going to be fixed? So I can just never use Firefox for as long as I have this cpu?
