Daniel,
Can the Firefox profile file hierarchy be sandboxed? So everything downloaded within the profile cache is sandboxed. More like if any application accesses something in a particular folder, sandboxing automatically kicks in.
You would need to setup something separately to do this. Sandboxing tool is by user choice. For example in firefox/thunderbird I can specify that any time it downloads content, firefox/thunderbird will run a command to view that content. rather then use evince or ooffice, I have them run sandboxevince and sandboxooffice, which are simple shell scripts wrapping sandbox command.
cat ~/bin/sandboxevince #!/bin/sh /usr/bin/sandbox -X /usr/bin/evince "$@"
cat ~/bin/sandboxooffice #!/bin/sh /usr/bin/sandbox -w 1400x750 -X ooffice "$@"
You can run your entire firefox session within a sandbox. Here is how I do this.
cat ~/bin/sandboxfirefox sandbox -i ~/.mozilla -X -t sandbox_web_t -W metacity -w 1000x900 firefox $*
Now getting apps to run sandbox when looking at certain content is something you would need to figure out.

Why isn't Firefox and Evolution confined with SELinux policy in a way
that
APT can't damage the rest of the system? Why are we not sandboxing these two apps with SELinux?
I've discovered some guidance for sandboxing Firefox using the 'sandbox' command. Once I test it a bit, I'll post the results back here. Seems
to
me that if this works, it should be the default.

Very difficult to sandbox thunderbird and firefox. But sandbox tool actually works well for sandboxing viewers of downloaded data. I sandbox all content that will be viewed by evince and libreoffice.
