Microsoft Edge Insider builds contain some features and functionality which are still in development or are exploratory, and are hidden by default until the team is more confident in their quality, or until a controlled feature rollout or experiment is complete. Experiment flags are used to enable and disable these features. You can access these flags by typing “edge://flags” into the Microsoft Edge address box. Each flag is displayed with a title, description, and a dropdown box which is used to display the current state of the flag and allows it to be changed. To find a particular flag, it may be useful to type keywords into the Search flags box at the top of the page.
You can directly access a particular flag by including it in the URL you type into the address box. For example:
- The Collections feature flag is accessed directly by typing “edge://flags/#edge-collections”
- The tracking prevention feature flag is accessed directly by typing “edge://flags/#edge-tracking-prevention”
Most flags have three options available:
- Default allows the flag to be set by Microsoft as part of an experiment or controlled feature rollout
- Enabled overrides the default setting and explicitly enables the flag
- Disabled overrides the default setting and explicitly disables the flag
Some flags have more descriptive options instead of or in addition to Enabled.
To change the state of a flag, simply choose a new option from its dropdown. A prompt Your changes will take effect after you restart Microsoft Edge will appear at the bottom of the window along with a Restart button. Click Restart and Microsoft Edge will automatically close and relaunch. Be careful to have saved any work in open tabs before you restart the browser.
Use caution when enabling experimental features. These features may be less stable than others and you could lose browsing data or compromise security and privacy.
