Image: Mozilla Mozilla is currently testing a new security architecture for its Firefox browser in nightly and beta channels that sees each site be put into its own operating system process. As it currently stands, when Firefox launches, it starts a privileged parent process, eight processes for web content, up to two additional semi-privileged web content processes, and four utility processes for web extensions, GPU operations, networking, and media decoding. With the set number of processes, the potential exists for a malicious site to be placed into a process already in use by another site, and giving it access to shared process memory.
