Trying to set up firefox-local for apparmor.d in Ubuntu
I am using Tor browser, which is based on Firefox. The 'About' tab says this: 14.5.6 (based on Mozilla Firefox 128.14.0esr)
When I sign in, it tells me that: "Some of Tor Browser's security features may offer less protection on your current operating system."
And it directs me to the following page: https://support.mozilla.org/en-US/kb/linux-security-warning?as=u&utm_source=inproduct
-- which directs me to set up a file called 'firefox-local' with specific contents. I have created this file; and pasted the recommended contents into it, and saved it.
I am then directed to issue the following command: sudo systemctl restart apparmor.service
-- which I have done. But that returns the following error: Job for apparmor.service failed because the control process exited with error code. See "systemctl status apparmor.service" and "journalctl -xeu apparmor.service" for details.
systemctl status apparmor.service gives the following output: × apparmor.service - Load AppArmor profiles

I don't know how to make heads or tails of this. Apparently the profile failed to load. According to the file documentation, it expects firefox to be located in '/home/<USER>/bin/firefox/' but I am running a version through Snap. and I think it is installed in '/snap/firefox/6700/usr/lib/firefox/firefox'
Is that the trouble; and how do I fix it? Grateful for any assistance; sorry for the data dump.
