Motivation for this new requirement is: ## Why
Each particular network your computer and browser run in has its own set of network conditions, routers, proxies and MITM situations. Changing between networks also changes proxies. Intercepting or explicit, willing or unwilling, HTTP or even HTTPS with custom installed trust-roots. This makes the web content cache, the cookie store and others to save contents from one network that is potentially different than what is received over other networks. It can lead to content pollution and information leaks, on purpose by malicious actors or just by mistake. see the details here https://bug1240932.bmoattachments.org/attachment.cgi?id=8709691 -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to apparmor in Ubuntu. https://bugs.launchpad.net/bugs/1628956 Title: From v49.0, Firefox needs read access to @{PROC}/net/arp Status in apparmor package in Ubuntu: New Bug description: Since the latest upgrade of Firefox to 49.0, it will need read access to @{PROC}/net/arp I don't know what the security implications are, so I don't know if we want to give read access to explicitely deny it. Both seem to work.
