This is basically an experimental feature tested on Chrome OS, but it is available in the trial. If you want to learn more techniques about boosting your browsing experience, you need to follow our complete guidelines to enable a flag.

However, no flag ensures stable performance. Moreover, finding bugs is a widespread occurrence in a flag. Besides, it would be best if you considered that flags are not tested on online security.
