@ledobg3: Thanks for checking in. I was wondering if it was possibly one of my extensions or something. I appreciate the Opera folks trying to continually improve the product, but yeah, Opera was already pretty much perfect, and as the saying goes, "If it ain't broke....." I was hoping that Kornelia might have seen this post by now, but....

@bigskytroutbum And why has Opera support been unable or unwilling to address this? I'm not an engineer or even a coder, but getting a "disable" button to actually disable an extension seems like a pretty easy fix to me.

@dalehcook Yeah, I'm about ready to bail also. After saying a few days ago that the frequency was minimal enough that I could live with it, it's started to get considerably worse. My Gmail page now snoozes after about ten minutes of inattention, and I know from experience, i.e., an overnight account freeze, that Google takes a dim view of excessive sign-in/refresh activity. It really does mystify me why the Opera people can't - or won't - make this very simple fix.

@gizmogadget No, I haven't actually left yet, GG, despite all my grumbling. Like you, I take a "compared to what" attitude toward this and I remember all the stuff I got tired of on Firefox and Chrome (Internet Explorer was always out of the question.) I did discover recently, however, and should have posted in case people didn't know, that it appears that the only tab that snoozes is the one that is selected, i.e., showing on the screen. Unfortunately, it happens pretty consistently with that tab, whatever site is involved. I'll look into that link you posted. Thanks again for all your work on this while the Opera people are still MIA. I gather this must be a part-time, side job for them.

@gizmogadget Thanks. Clearly, I've got something else besides the new tab snoozing bug factoring into this. I run AdBlock Plus, in addition to the on-board Opera ad blocker, Ghostery, and Privacy Badger. Probably a little overkill there, but I've been running all of them for years with no problems. I already had trackers blocked, but discovered I only had 3rd party cookies blocked in private mode; turned on blocking of 3rd party cookies entirely.

Actually, your extension is working well enough that I can live with the status quo. These tabs don't snooze often enough to be really annoying and they refresh very easily, usually just by rolling the cursor over another part of the page. Just seems like more work than it's worth to go through all these various add-ons and extensions to finally pinpoint the issue. That Rolling Stone site is one that I might visit twice in a year, and my everyday sites are behaving very well. So I'm going to call this good. Thank you very much once again. I'll continue to have an alert enabled for new posts on this forum, if anything new surfaces and the mystery is finally solved. Who knows? Maybe the Opera people will finally take an interest in debugging this new, unneeded and unwanted feature. Just seems like they might have taken a look to see if it actually worked after releasing it.

@gizmogadgetBad news: Just had two episodes a few minutes apart on this web page https://www.rollingstone.com/culture/culture-news/the-lyman-familys-holy-siege-of-america-235776/ which I'd opened only about a half hour earlier. I discovered the second episode upon returning from ten minutes away from the screen. Neither time did I get the "disable tab snoozing" button option at the top of the screen, and each time the page refreshed easily, but they did nonetheless snooze.

@gizmogadget Well, your "new" tabs theory is looking pretty good, GG. As per the above post, I restarted Opera, opened my eight favorite tabs, left them running all night and, some ten hours later, none of them has snoozed. Your workaround extension seems to be getting the job done. I'll check back in if that changes. Thanks again for your time and help.

@gizmogadget I just restarted the browser and opened each of my usual tabs, which now qualifies them as "New" tabs, right? I'll leave them running overnight and see in the morning whether the Snooze Fairy has paid me a visit. Just realized that I neglected to include https://www.ebay.com in that list of tabs that I keep open continuously. Signing off for tonight; will report in the morning.

Cheers, as you Brits say.

@gizmogadget Well, for what it's worth. I recall the snoozes to have happened rather randomly in terms of time, i.e., sometimes after a few hours, sometimes sooner, etc. I'm leaning more toward your "new tab" theory, however, and will test that out forthwith by restarting my system and browser. I hope I haven't wasted a lot of your time with a false alarm as to your extension workaround.

@gizmogadget OK, that "new tab/open tab" distinction may very well be dispositive. I go a week or more at a time without powering down or closing the browser. I'll power down tonight and see what happens.

Again, why does Opera leave it to the users to solve this? I originally reported this on the blog page that announced the new feature (https://blogs.opera.com/desktop/2021/02/opera-74-stable/)
It would appear that Kornelia doesn't bother to read the comments on any of her blog posts. No one from Opera appears to be reading this forum either.

@gizmogadget One of them was Yahoo News (https://news.yahoo.com) earlier tonight, which was what prompted me to post. I'm sorry, but I don't clearly remember what the other one was, but it was almost certainly one of these which I keep open continuously:
https://www.vox.com
https://www.politico.com
https://www.npr.org
https://thebulwark.com

And, now that I'm concentrating on it, I remember it happening on this very forum page (How's that for irony?), but I can't remember whether that was before or after I installed your extension.

Hope it helps; please let me know.
