I noticed a behavior change around June 2026 when using the "Launch new Microsoft Edge" action in Power Automate Desktop.
When Edge is configured as:
 Settings → Start, home, and new tabs → Open the new tab page
and PAD launches Edge with an Initial URL using a new browser instance, two tabs are opened:
Previously, only the specified URL was opened.
Has anyone else experienced this behavior?
As a temporary workaround, I was able to avoid the issue by configuring Edge to:
- Settings → Start, home, and new tabs → Open tabs from the previous session
- Clear browsing data (cache, cookies, etc.) whenever the browser is closed
Any related information, release notes, or workaround suggestions would be greatly appreciated.
I can also reproduce the same behavior by launching Edge directly from Command Prompt, which makes me suspect this may be related to a recent Edge change rather than PAD itself.
This causes the following issues:
- PAD's "Close web browser" action closes only the URL tab, leaving the New Tab page open.Edge windows remain open after flows finish.
- Subsequent flows may create additional Edge windows.
- UI automation steps may fail when multiple Edge windows are present.
Environment:
- PAD 11.2605.237.0
- Edge 149.0.4022.80
- Power Automate extension 2.68.0.34
