I was looking at the System Activity today on Linux Mint KDE 17.2 and I noticed Firefox has root access. I found this out by typing fire and I see a process called rcuos/3 with the Firefox icon next to it. Is this normal?

Yes.  It does not mean that firefox has stuff running as root.  Internal kernel scheduling entities (Read-copy-update) that are used for scalability and smoothing out OS jitter.  Firefox is likely the parent process that caused them to come into being.

Thanks.:) Also I discovered this only happens when running Firefox with Firejail.
