@genegold Yeah, without an option to disable the auto-update, restoring the system is useless.

Even though I received the last update (101.0.4843.33), it happened to me again, 200+ tabs lost, fortunately I had them backed up in speed dial this time, but man this is becoming so tiresome.
I don't think I can take this anymore, I'm considering moving to Firefox definitely.

@mixchild Yeah, I wouldn't hold my breath waiting for it, though (sigh).
But hey, one can dream, right?

@balduin01
I just opened my Opera browser with version 101.0.4843.43, and it happened the same.
And while I'm writing these lines, it's downloading the update.
I don't know why they didn't fix this already, because this is a major problem!!!

@dermotmoconnor
Yeah, I really don't know what's happening that they didn't fix it already, because it hurts so bad the reputation of a browser that's not even in the top 3 regarding popularity IMO.
Any new user that discover this bug, will think this is a piece of garbage and will uninstall it without thinking it twice.
And I say it because I'm starting to thinking of doing it myself, because at this point I'm loosing hope that this will get fixed anytime soon.

The problem has worsened, with version 101.0.4843.58, I opened Opera to find now it erased me 200+ tabs from another workspace (not the one I was in when I closed the browser before shutting down my PC).
It's becoming impossible to use this browser anymore.

@beorn1 Same here, I'm quite happy with Vivaldi right now, it's the next best thing if you want something similar to Opera.
It has a different approach on some of it's features, but the level of customization makes up for it, to adjust it to my needs.
And most importantly, it hasn't nuked my tabs either.

@beorn1
It didn't happen to me (yet), but thanks for the heads-up, I will back up my bookmarks.
But yeah, this browser (since the damned "ONE" update) has been going from bad to worse, it looks like they are sabotaging themselves more and more with each update, and I'm reaching my limit.
If I loose all those things like you did, I'll uninstall this piece of trash browser (that's what it has become by now) for good.

Since the new "Opera One" came in with the autoupdate, I've been having numerous problems (like randomly loosing all my tabs within the workspace I was on when I closed the browser the last time I used it; or not being able to drag a pinned tab within the group of pinned tabs), but recently, when I was trying to organize my workspace, I noticed that I couldn't drag any tab beyond a certain point (I have 200+ tabs in that workspace, so keeping it organized is important for me).
I also noticed that the distance that the browser allowed me to drag a tab was hard-capped, but it was longer, the higher the resolution from the screen I had the browser window in (weird, uh?).
i.e.: Being able to move a tab to the right, not past the 36th tab in one screen (1080p), but being able to move it to 50th or so on the other screen (1440p).
I don't know what happened, but since this new "overhauled" version of the browser came out, my user experience with this browser has gone from awesome to absolute dogsh#t, overnight.

@fan4eggg
It happens to me everyday, it's so annoying, ever since the new "Opera One" came out, the browser became a wonky piece of trash (even to the point when I open it, I discover that it erased all my tabs from the workspace I was on when I closed it).

@ittekhanh
That's not what the OP was asking for.
Like what happens if I want to organize the tabs I have within one of my workspaces, or even better, what about having to move a group of tabs I have in another window???
You can't, you have to use the "Pin Tab" function to "force" your tabs into the order you want, or sending them to another workspace, and then move them back to the original one, to get the same result.
It's ridiculous that they didn't put this function already, while Chrome and Firefox did it years ago.
