@melosense Thanks for reaching out, and welcome to our Insiders community.
We're so sorry to hear that you're encountering some issues with Microsoft Edge! If you're still seeing this, we'd love to help troubleshoot. Are you seeing the same behavior on other channels, or just the Stable channel in version 80? And if you haven't yet, can you please submit feedback and diagnostic data through the browser? Our devs would love to be able to help get to the bottom of this in a secure way that respects your data privacy. And if you have any issues with the Stable build going forward, feel free to check out this help site and/or contact our support team directly here.
