I think that's what happened when I did not know Opera updated? So, is there a way to get back my old bookmarks from Opera browser?

No, I did not paste the bookmarks file from Chrome into Opera's profile directory. For some reason, my bookmarks from Chrome auto installed into my Opera browser. How did Opera do this?

No. The bookmarks got overwritten by my Google Chrome ones. Is there a way to reverse or is there something from the Opera files to find it?

Hi. I don't know why my Opera browser just decided to delete all of my add-on extensions and bookmarks after just closing it for a night. The bookmarks that I have now for Opera browser came from Google Chrome so It got replaced for some reason. So, how do I recover my previous Opera Browser bookmarks? Is there a secret method or a tool you can use? Please help. Thanks.
