About ://flags page formerly known as about:labs page available on Chromium and dev. and Canary builds of Chrome, these flags are experimental features under development being aimed at developers and advanced users and not for regular users. That’s why they are disabled by default. Interested users can test them by turning one or more features, browser needs to be restarted for the changes to take effect.
Chrome://flags or about:flags page warns user “these experimental features may change, break, or disappear at any time”. And implications of turning one or more experimental features could burn your browser and can yield data loss and result in compromise of privacy and security.
How to Reset all Chrome flags to default
So if you’ve enabled few experimental features you need to disable them after testing. But you need to carefully look for which flag is enabled and which flag is disabled?, after all there are 133 flags. So finding each enabled flag and disabling it again can be tedious and takes some time, keeping this in mind Chrome team has added “Reset all to default button” on top of Chrome flags page which you can use.
So to reset all Chrome flags to default
1. Visit about:flags in Chrome dev. channel
2. Click on “Reset all to default” button
3. And scroll down to bottom and click on “Relaunch Now” button for the changes to take effect.
Currently this option is available on Chromium and Canary builds. [Thanks to Francois]
