I am assuming that an update to Opera had been performed automatically. I opened the browser for the first time today, and absolutely everything is missing.
I have no Bookmarks, my Speed Dial is all missing, there is not even any browsing history. The history goes back 20 minutes ago, when I opened the browser today.

I had tons of bookmarks...many to sites for paying my bills, accessing mortgage information, etc.
Please tell me that Opera performs a backup of those items prior to an update and that I don't have to try to rebuild all of the bookmarks and speed dial entries. I don't think I can do that and capture everything that is gone.

@sgunhouse Thank you for the reply.
I have not been able to locate any relevant information in threads on here, which is why I made this post.
When Opera is open, I have only 2 options...full screen or minimized.
If I Alt-Space, I see the following:

All options are greyed out with the exception of Minimize and Close.

So, my 1 y/o grand daughter decided to start smacking the keyboard while Opera was in focus, and Opera is now locked in full screen. I cannot access any menus, tabs, bookmarks, etc.
I am running the latest version of Opera (can't tell you which, since I cannot access any menus.)
I am also on a Windows 10 PC.

When I launch Opera, it defaults to full screen.
If I hit F11, the window disappears, but it resides on the taskbar.
I have no context menus in the taskbar.
I cannot Restore, Maximize, etc.
The only way to see Opera again is to click it in the Taskbar, and hit F11 again....and it returns to full screen mode.

I have no idea what key combo my grand daughter must've hit.....and I am loathe to try reinstalling...as I do not want to lose the multitude of bookmarks that I do have.

Any assistance would be greatly appreciated!
