@Thomas, some of the rules are related to E10S but a lot predate it. I noticed you opened quite a few bugs with regards to Firefox's profile, most of those would have been fixed had one included my local/usr.bin.firefox rules into the main profile as shipped by the package.
I try to keep the local rules up to date in LP: #1533232, hoping that someone will include them in the main profile someday :)
