@burnout426 By right clicking on Opera's taskbar button while it's closed and choosing "New private window" to start it, yeah.

@leocg Sorry, Nah, I open an incognito window maybe thrice per week.
On my normal window I tend to have things that I open once and do not close for a long time, like music sheets or a post about how to solve an issue, that some day I'm gonna try to follow.

But as Opera is not my main browser, it is not uncommon for me to not open any Opera window for a week or more.

And that's when I'm hit with the update + wipe combo.

@leocg Hi!
I didn't restart it. As a matter of fact, this happened multiple times to me, and it was always the same. First and only window to open at that time was an incognito one.

I turn on the PC, I open an incognito window (maybe just after it turned on, or after half a day) as first and only Opera window and if it shows the animation that indicates Opera has been updated, I know I lost my tabs.
Always after that sequence, my normal tabs are wiped.

Which Opera? It is not GX nor Air, so I guess One? It is the basic one most people download through a Google search.

It is funny. I still keep finding my previous post about this issue on Google.
And for a time they did fix it! Everything was fine!

But today I opened an incognito window and it updated. After that, when I closed the private window and opened a normal one, everything was gone.

Even as a secondary browser this is a bad option at this point..

At this point I'm not leaving useful tabs open on Opera anymore, but it is still annoying when this happens.

If I open Opera on incognito (with no other Opera windows active), and it happens to load that incredible annoying window with sound (Genius idea, btw. You should try adding something like the old SWF autoplay videos on loop of the old days. People would surely love them too!), that I guess happens when Opera gets an update, all my tabs on my normal session are lost.

So, in short:
I open Opera in incognito.
That annoying thing pops out.
I close the incognito window.
I open a normal Opera session.
It opens with only a new tab open. All my previous ones lost.

At this point I'm not even interested on geting them back. But dude, how can this still keep happening? I posted about this same issue months ago.

Windows 10 and latest Opera version to this date.
