Yes I know you are all thinking... "Another permissions question", but I am stumped! And I did my looking!
I have a /usr/local directory that firefox is in and with this new install, other users beside root can't access it. I have used chmod on it but maybe my syntax was wrong, as when I booted into a test user I couldn't load firefox. And it works, because root can access it. My friend told me to edit the /usr/ in fstab but that will give permission to write in the entire directory and we don't want that do we? And for measure, users also can't access the /usr/ directory, not just /usr/local.
