Did you others bug report it? Feel free to use my BR number, BS-70469, under the subject:
"Re: BS-70469 While opening new blank tab Opera instead restarts"

@genegold: I've just discovered that it automatic updated, so I can't escape this horrible version. What to do?

@renatob: Wish I knew. There was a forum topic about it, but the solution was complicated. There is a real need for an auto update off/on setting.

@burnout426 Thanks. So as I read your post, given the changes over time, the only thing needed now to account for my previously added syntax is renaming the autoupdate file. I do have zoom set for 80% (wish there were 5% options between 80 and 100).

Is there a way to turn off the sound Opera makes on start up?

@burnout426 Thanks.

Thanks. Those don't seem to be it. Each file is different, but examples are not something I'd want to post on a public site. I've got IDM looking into it too. I just wondered if there's a Save As setting, like their used to be as I recall (accessible in Windows settings)

@renatob: Go a system restore. The problem is auto update is apt to occur sometime after. This is a real cluster f***

Probably not. The changelog shows last Chromium update on Sept 26, while this started with the Win 10 and O64 updates on Oct 8.

@genegold: Just did it again. Several tabs open, click on + to open a new tab and instantly the splash screen is playing and a new sessions starts (w/o all the open tabs). It's happened every day since I installed this version.

@leocg Thanks.

Opera 105.0.4970.13, Win 10 Pro x64 desktop

This page is supposed to show regular and sale prices, as it does with other browsers. It's not doing so with Opera, even logged in, because it sees me as outside the U.S. Further evidence of this is that when I open any of the items, there's a "This product is only available through a dealer in your area." The company doesn't use dealers in the U.S., only elsewhere. I've deleted cache, history, etc., i.e., everything but cookies. Is there anywhere to delete cookies for one site only? The result of doing so generally is a PITA.

In moving around SD thumbnails, occasionally I end up with a couple in an unintended folder. Is there a way to extract the separate thumbnails, short of "opening all" and recreating the individual items?

@burnout426 Programs don't ordinarily say they are creating a restore point during install.

In Win 10, when I open System Restore and consider which restore point to use, the affected programs list doesn’t include Opera, even when there have been multiple updates, as there were a couple of days ago. Why? Updates for FF and Edge show. And back with Opera 102, when an update messed with extensions, Opera was there and System Restore was able to go back to the previous version. No more?

How do we get rid of the Halloween(?) pot at the top of the SD, wasting space?

@genegold: I figured it out. There's a vertical purple "I" over on the right that has to be clicked on to show extensions. Why Opera disabled this by default on update -- and without saying anything? -- is anyone's guess and really annoying. Trying to figure out what happened and restore what I had took a good part of the afternoon.

However, fixing that doesn't explain the Windows system restore issue.

I figured it out. One has to click on the purple vertical "I" on the right, which then shows extensions. Why Opera is setting this not showing by default on update is really annoying. Trying to figure this out and the various steps I tried to get back the extensions wasted a good part of the afternoon.

There were a few updates to Opera for Windows in the past 24 hours. Sometime in there, update did it again, that is eliminated my extensions from the Address Field level (right). Opera did it last month and then I used system restore (Win 10 Pro 22H2). But even though I create a restore point each night before shutting down, Opera is not listed among the programs affected (why not?). Which leaves me in a big pickle: How do I get my extensions back showing (AdBlock, IDM, etc.)? I've submitted bug reports on both issues.

Below is what's showing now, but for some reason the file showing the extensions from before gets an error message on uploading here.

@genegold Even worse, this time I can't figure out a way to go back via system restore, because even though I create a restore point each night via Windows 10, Opera is not showing in the programs affected, not any day. Why not?
