I don't know what happened. A mere two days ago my tabs were in my other workspace and now that I would have liked to access them again, they are simply gone. And, simply put, I haven't done anything that could have done this. Opera didn't tell me of any errors either so I have absolutely no idea what could have caused this. The only thing I can think of that could have caused this is Opera's newest update. Although this has happened twice now in the last two to three days, so I'm not sure about that one either. (First time was only a few tabs, so I thought I had mistakenly done something. Now that it happened again though, I am sure it was not me.)

Is there any way to get my tabs back? Is there a button like in some other Chromium-based browsers where you can open recently closed tabs? I have searched for one but haven't managed to find it.

I noticed that all the tabs I have lost are still in my history but there were quite a lot of tabs open as I am bad at closing them, so manually opening them all back would be very cumbersome. Is there, perhaps, a way to mass open tabs from history?
