It seems that the "In-page search" feature in Edge 128 now opens in the sidebar. This sidebar can also open other websites, creating potential loopholes for filters, which is very troublesome.
Does anyone know how to prevent the sidebar from opening?
@YamadaKsk Hello - I just spoke to the team. Currently there is a new experiment for Find on page, which is what you've encountered.
You can switch back to the flyout by clicking the circled button in the screenshot.
Also, if needed, you can disable this experiment at edge://flags/#edge-sidebar-find-on-page. And you can provide feedback directly to the team through our in-browser feedback tool. It's under "..." menu > Help and feedback > Send feedback. Thanks!
