Today I discovered that Firefox 8.0 on Ubuntu 11.10 wanted to have read access to /proc/[0-9]*/fd/.

I have made a custom usr.bin.firefox apparmor profile so I have spent many hours testing, but Firefox never wanted to have read access to the /proc/[0-9]*/fd/ directory before, and now suddenly it want it every time I browser the web.

The orginal apparmor Firefox profile or any af the abstractions do not allow read access to /proc/[0-9]*/fd/ so I do not understand why this is suddenly happening.

Does it sound reasonable that Firefox want to read the /proc/[0-9]*/fd/ directory? or is my system defective?
