Chrome Canary tests asking users where extensions can run
A pop-up in Chrome Canary offers 'When you click the extension' as the default and 'Always on all sites' as the alternative.
Google is testing a feature in Chrome Canary that replaces granting extensions access to all websites by default, according to androidpolice.com. The test surfaces a pop-up when an extension is added, asking the user to choose between "When you click the extension" and "Always on all sites."
The default option in the pop-up is set to "When you click the extension," so an extension would not run across every site unless the user selects "Always on all sites." The feature was first spotted by leaker Leopeva64, who demonstrated it in a hands-on demo.
The change is likely to affect extensions added in the future rather than ones already installed. It is currently being tested in Chrome Canary, and there is no official word on when it will reach Stable Chrome.
Manifest V3 context
A few years ago, Google replaced Manifest V2 with Manifest V3 despite backlash from users and developers. Google said Manifest V3 would improve the privacy, security, and performance of extensions.
