@leocg I found out how to back up and restore my windows and tabs, by using "Save All Tabs as Speed Dial Folder." I did that and started deleting workspaces.

I ran into a problem. Workspaces apparently requires the existence of at least two workspaces. That's the whole idea of workspaces. So once I get down to two workspaces, there's no option to remove either of them.

So I can't reset workspaces that way.

@leocg I tried removing them. But I don't want to remove a workspace that has tabs in it because I don't want to lose any of my tabs, and I can't move tabs when I can't see them (see https://forums.opera.com/topic/55951/hidden-tabs-in-some-workspaces/1).

Suppose I remove a workspace and then disable workspaces, What happens to the tabs and windows that were in that workspace?

1. Can I recover them by using Menu / History / Reopen Last Closed Window?
2. If so, will they reopen in an existing workspace or will the workspace they were in be automatically restored?

My workspace setup is corrupted. I disabled workspaces so I can use Opera, but when I reenable workspaces I get the same old corrupted workspaces back.

How can I reset workspaces and get back to where i was when I first enabled workspaces?

@marty39 I dissolved the issue by disabling workspaces. All my lost tabs immediately appeared in the currently open window. That was far too many tabs for one window, so I had to move most of the tabs to other windows. But the issue is only dissolved, not solved or resolved.

I would like to be able to use the workspaces feature, but when I reenable workspaces I get the old workspace setup back, with tabs hidden in some of the workspaces. Evidently my workspace setup is corrupted. I would like to reset my workspaces (to where it was when I first enabled workspaces) but I don't know how.

I'm using workspaces. I don't need all my workspaces. I selected a workspace I hadn't used recently. I got a window that showed only one tab, showing the start page. I clicked the little red button that closes the window. I got a popup that warned me that I was closing a window with 9 tabs.

I tried restarting Opera, restarting the Mac, shutting down the Mac for a minute, and even starting in safe mode. I didn't reset settings to default because I don't know how to "do a backup and export [my] passwords," nor did I do the subsequent steps.

I want to see those hidden tabs so I know what I'm closing.
