To use SurveyTester in an Incognito window, Chrome needs permission to run the extension there.
chrome://extensions
In Edge, Incognito is called InPrivate. Go to edge://extensions → SurveyTester → Details →
enable Allow in InPrivate.
Your survey has been successfully opened in a separate Incognito window.
This tab was used only to start the Incognito session and may remain open in some cases.
You can safely close this tab now and continue testing in the Incognito window.
For an enhanced survey testing experience, install our browser extension. It streamlines communication with survey developers and makes testing simpler, faster, and more efficient.
You can usually install Chrome Web Store extensions in Edge too, but you may need to enable Allow extensions from other stores in Edge’s extensions settings first.
Open edge://extensions and look for that toggle.
The SurveyTester Browser Extension is currently available only for Chromium-based browsers. It won’t run in Safari or Firefox.
After installing a Chromium browser, open this SurveyTester page again and install the extension.
SurveyTester uses a Chrome MV3 extension to integrate directly into survey pages and automate test runs. Safari and Firefox use different extension platforms, so the current extension cannot run there.
SurveyTester detected that there is already an active Incognito window.
All Incognito windows share the same temporary browser session.
Cookies and survey data from another Incognito window may influence this test run.
For a clean test start, please close all other Incognito windows and then retry.
Advanced users can continue anyway if shared Incognito state is intentional.
