I want resource usage confirmation. Limit each site to a megabyte. If it wants more, it can wait until I approve a doubling. Each doubling needs my approval. For example, upon hitting 128 MiB, the site should freeze up until I give the OK for going up to 256 MiB. Limit each site to a single thread. Let me approve more or just force the site to live within a limit. Limit each site to running in the foreground. (only the visible tab of the currently focused window runs) If I really want something to run in the background, let me indicate that with a right-click menu on the tab.
