Could it be that you have some kind of sync enabled for your browser history? Depending on the browser you use, browser history, bookmarks, extensions or even open tabs might be synced across your devices. For example if you login to your Windows 11 with an online account, you'll most likely already be logged in when using MS Edge. So you should check your browser's settings for synchronization features you might have enabled.
You could also verify that by restoring to a previous backup while having your PC disconnected from the Internet.
