Hi there,
I'm Cherrelyn, and I’m here to help.
If hidden tabs in Microsoft Edge aren't visible or movable, try right-clicking the Edge icon in your taskbar, then selecting the tab from the list to bring it forward. If that fails, restarting Edge or your PC may force the tab layout to reset. For blocking specific websites, Edge doesn’t offer a built-in allow/block list for users, but you can manage content using parental controls in your Microsoft account or use an extension like "Block Site" to manually define which sites to block.
I hope this will help and if you have any question please don't hesitate to reply to this thread.
Warm regards,
Cherrelyn
