--enable-strict-site-isolation Experimentally ensures that each renderer process: 1) Only handles rendering for pages from a single site, apart from iframes. (Note that a page can reference content from multiple origins due to images, JavaScript files, etc. Cross-site iframes are also loaded in-process.) 2) Only has authority to see or use cookies for the page's top-level origin. (So if a.com iframes b.com, the b.com network request will be sent without cookies.) This is expected to break compatibility with many pages for now. Unlike the --site-per-process flag, this allows cross-site iframes, but it blocks all cookies on cross-site requests.

--trace-startup Causes TRACE_EVENT flags to be recorded from startup. Optionally, can specify the specific trace categories to include (e.g. --trace-startup=base,net) otherwise, all events are recorded. Setting this flag results in the first call to BeginTracing() to receive all trace events since startup. In Chrome, you may find --trace-startup-file and --trace-startup-duration to control the auto-saving of the trace (not supported in the base-only TraceLog component).
