Since some people have also expressed confusion about the multiple processes running as part of Pale Moon, a brief description of processes:
- Pale Moon web browser: this is the actual browser
- Plugin container: this is Pale Moon's container process for plugins - it's separate so that crashing plugins will not crash the entire browser as well, making you lose work. This is called OOPP, or Out Of Process Plugin-execution. The container itself is minimal, and if you see it using a lot of CPU/Memory, then that is because of the plugin running in it (not Pale Moon's responsibility)
- Flash player .exe: Later versions of Adobe Flash further externalize by having the plugin (running in the container) spawn another process that does the actual work. So this is why you see yet another process in your task manager whenever you visit a web page with Flash content.
