Enables on-focus suggestions on the Open Web, that are contextual to the current URL. Will only work if user is signed-in and syncing, or is otherwise eligible to send the current page URL to the suggest server. C Mac, Windows, Linux, Chrome OS, Android

Preserves the default match against change when providers return results asynchronously. This prevents the default match from changing after the user finishes typing.

Allows autocompleting bookmark, history, and document suggestions when the user input is a prefix of their titles, as opposed to their URLs. C Mac, Windows, Linux, Chrome OS

Allow autocompletion for titles and non-prefixes. I.e. suggestions whose titles or URLs contain the user input as a continuous chunk, but not necessarily a prefix, can be the default suggestion. Typically, only suggestions whose URLs are prefixed by the user input can be. The potential variations toggle 4 params: 1) 'Title UI' displays titles, 2) '2-Line UI' includes titles (and URLs when autocompleting titles) on a 2nd line, 3) 'Title AC' autocompletes titles, and 4) 'Non-Prefix AC' autocompletes non-prefixes. C Mac, Windows, Linux, Chrome OS

C Mac, Windows, Linux, Chrome OS, Android

Enables forced colors mode for web content. C Mac, Windows, Linux, Chrome OS, Android

Starts heap profiling service that records sampled memory allocation profile having each sample attributed with a callstack. The sampling resolution is controlled with --memlog-sampling-rate flag. Recorded heap dumps can be obtained at chrome://tracing [category:memory-infra] and chrome://memory-internals. This setting controls which processes will be profiled since their start. To profile any given process at a later time use chrome://memory-internals page. C Mac, Windows, Linux, Chrome OS, Android

Heap profiling service uses Poisson process to sample allocations. Default value for the interval between samples is 100000 (100KB). This results in low noise for large and/or frequent allocations [size * frequency >> 100KB]. This means that aggregate numbers [e.g. total size of malloc-ed objects] and large and/or frequent allocations can be trusted with high fidelity. Lower intervals produce higher samples resolution, but come at a cost of higher performance overhead. C Mac, Windows, Linux, Chrome OS, Android

By default heap profiling service records native stacks. A post-processing step is required to symbolize the stacks. 'Native with thread names' adds the thread name as the first frame of each native stack. It's also possible to record a pseudo stack using trace events as identifiers. It's also possible to do a mix of both. C Mac, Windows, Linux, Chrome OS, Android

Accepts Origin-Signed HTTP Exchanges to be signed with certificates that do not have CanSignHttpExchangesDraft extension. Warning: Enabling this may pose a security risk. C Mac, Windows, Linux, Chrome OS, Android

When enabled, the distributors of signed exchanges can let Chrome know alternative signed exchange subresources by setting "alternate" link header. Chrome will prefetch the alternate signed exchange subresources and will load them if the publisher of the main signed exchange has set "allowed-alt-sxg" link header in the signed inner response of the main signed exchange.
