Tab Snoozing
I have recently begun to notice that a web browser is displaying a message of "The tab was snoozed to save memory". I have been able to locate only a little information, not much, about tab snoozing. I infer that this means that, if I have multiple tabs open in an instance of the web browser, the ones that are snoozed are no longer kept in memory. Is the tab written out to the swap file, or just released? If I click on the tab again, is the tab refreshed from secondary storage (swap file) on my machine, or is the tab refreshed by reading it from the remote web server? Is this a relatively new feature of web browsers, or is this something that I haven't noticed until now? If Wikipedia has an article on this feature, then it isn't in an obvious place, because snoozing takes me to sleep without a hatnote. If there is an article, where is it? If there isn't an article, maybe a WikiProject needs to develop it. The obvious advantage of snoozing is that it saves memory, and so reduces the hard faults. The obvious disadvantage is that the tab has to be reloaded if it is clicked on. Are there any unobvious advantages or disadvantages that I ought to know about? I see that Opera under Windows 10 does snoozing. Do Firefox, Chrome, and Edge (under Windows 10) support snoozing? Where is there more information about it?

 * Edge: Yes, and it was recent. — Preceding unsigned comment added by 116.86.4.41 (talk) 04:31, 27 February 2021 (UTC)
 * AFAIK, Chromium based browsers have always done it if memory is running low or it's more economical to not render the tab. I think only now they're letting you know they're doing it. ✨ Ed  talk!  ✨ 05:27, 27 February 2021 (UTC)

Animation of Web Pages
How do I turn off the animation of web pages, either in the options for a web browser, or on a page-by-page basis? Sometimes it is useful, but it has disadvantages. On a laptop running on battery, it is a current hog. Also, it prevents the system from turning off the screen. Robert McClenon (talk) 03:39, 27 February 2021 (UTC)


 * For starters, what browser are you using? I know how to do it in Firefox, but... --142.112.149.107 (talk) 03:57, 27 February 2021 (UTC)
 * Sometimes I use Firefox. Sometimes I use Opera.  Sometimes I use Chrome.  So I would like to know how to turn off the animation with each of these three browsers.  Robert McClenon (talk) 17:38, 27 February 2021 (UTC)
 * Okay, in Firefox you go to pseudo-URL about:config and you want to set the image.animation_mode parameter. (Type part of its name in the blank at the top to bring it onto your screen.)  If you set it to none, animation is turned off.  If you set it to once, as I usually have, an animation will play once through and then stop.  --142.112.149.107 (talk) 21:48, 27 February 2021 (UTC)
 * Occasionally the animation has explanatory value, but often it is just there because it seems technically neat, e.g., to show that the programmer knows how to do animation. Robert McClenon (talk) 17:38, 27 February 2021 (UTC)

Can Facial recognition system identify a person before and after cosmetics?
Please glimpse the thread at Wikipedia:Reference_desk/Entertainment § Who. My question is that can modern Facial recognition system tell if File:Kim Tae-yeon at Incheon Airport on August 29, 2019.png was falsely named to Kim_Tae-yeon or not? Thanks.

 * Yes, facial recognition system are easily fooled. Cosmetic would suffice in many cases. Just look at the Anti-facial recognition systems section of the article you linked to. Humans are, obviously, way better than any ML algo.--Bumptump (talk) 16:32, 28 February 2021 (UTC)
 * Ahh, I see! Thank you so much for joining the discussion! ^__^ -- Stringent Checker  [bargaining]  03:24, 1 March 2021 (UTC)
