Test extension don't work in tab with Cypress

[valentin-kushnarev]

In the Chrome tab showing the progress of the Cypress test, my extension is not working. In the next new tab of the same browser (which launched Cypress), my extension works.

The extension is connected to the browser. It appears as enabled, but it does not perform its function in the test run tab.

As if there is a conflict in the window where the Cypress interface is displayed and the interface of my extension should be displayed.

Tell me, please, how to solve the problem?
