Worth investigating.
Cool, it has a man page :) I checked the files/directories mentioned in the page, and nothing seems to indicate that there is anything that would allow firefox to increase its priority. It might not need a special allowance because I have allowed the user to set a nice level of up to -10 in /etc/security/limits.conf. I think that doesn't mean that firefox could get real time priority though --- unless rtkit-daemon is somehow able to set any process that asks for it to whatever priority the process asks for. If rtkit-daemon can do that I wonder why the default configuration is made to open such an enormous security backdoor.
