It adds a list of the most recently closed tabs to the tab context menu

Some ways to try to revert it (some have already been mentioned)

👉 Go to this page and check if you're able to opt out of the "Redesigned Watch Page" (source)

👉 Install a userscript addon like Violentmonkey, and then use a script like Classic Youtube Layout (which is based on this script which was outdated in regards to the related videos sidebar)

• If you get an error about the @match line of the script then click on allow edits and change it from *.youtube.com/* to *://*.youtube.com/*, or install the script as it is and then put *://*.youtube.com/* in the "@match rules" line in the settings tab of the script
• There's also this script that you would need to add its code manually to the userscript addon by clicking on the new script icon (see the author's post for more details)

👉 Use uBlock Origin filters like these or these

• Note that youtube.com##+js(set, yt.config_.EXPERIMENT_FLAGS.kevlar_watch_grid, false) should be enough to change the UI back for the most part

👉 Use this userscript and Stylus style

👉 The addon Enhancer for YouTube (Firefox / Chrome) also reverts the UI, at least partially

👉 (might only work some times) Use the addon CustomTube - Firefox / Chrome (the default UI is from 2017 but you can choose 2021 in the settings. It's not exactly like the one from 2023 but it's close enough)

• note that it removes some buttons like Join by default so go over the settings if relevant

If you also want to change the number of videos per row in the subscription page and channels' videos page, then you can add this uBlock Origin code to the "My filters" tab (at the end click "Apply changes", or Ctrl+S) (this is for 6 items per row but you can change the number in the first 2 line as needed) (source 1 / source 2)

Sure thing, here it is in a new profile, though for some reason I couldn't get the tab height changes to work without using the browser.tabs.secondaryTextUnsupportedLocales setting

Sorry, it was unclear in my comment. By "it’s actually part of the Mozilla Corporation" I was referring to Firefox, not Mozilla Foundation

for anybody that wants to disable it, go to the settings and search for "Allow websites to perform privacy-preserving ad measurement"

(or through the dom.private-attribution.submission.enabled flag in about:config)

https://support.mozilla.org/en-US/kb/privacy-preserving-attribution

It can be 👍

I also didn't have a need for it and wanted to disable it and I found browser.tabs.hoverPreview.enabled in about:config (set it to false to disable).

There's also browser.tabs.hoverPreview.showThumbnails to only disable the image preview but not the new layout of the tooltip (there's also a corresponding option for it in the main settings)

• Lights: Switching to light sources/bulbs with lower brightness/warmer light temperature (lower Kelvin/K-value) 3 hours before bed. (Light affects our sleep-wake cycle, aka the circadian rhythm. Our brain processes bright light as "the sun is still up so it's not time to sleep yet")
• Screens: Gradually dimming electronic screens until bedtime (Computer: using F.lux and lowering the brightness gradually in the graphics card's control panel. Phone: with a built-in Night/Dark Mode option that you can schedule or by using an app like Twilight). // Don't take your devices to the bedroom, or keep them far away from the bed and set them on silent/shut them off.
• Sleeping in a closed and completely dark room (including covering LED lights on electronics, or using a face mask) with something that makes a white noise.
• Food: Having a light meal 3-3.5 hours before bed and light snacks 1.5-2 hours before bed, to not put the body into overdrive digesting a heavy meal or cause heartburn/indigestion, and also to not go to sleep hungry and get distracted by that.
• If you sleep on your stomach with your head to the side, you can use a thin and narrow side pillow (but firm) along your torso to support your shoulder on the side that your head is pointing to. (you can also use a thin pillow for your head to not strain your neck/spine - there are ones made for kids if needed)

On the humorous side:

• My Brother, My Brother And Me - 3 brothers giving not-so-serious advice to listeners, reacting to questions from Yahoo Answers (when that was a thing), and later adding other segments, and overall being funny/silly (note: sometimes they make references that go over my head, but they're still enjoyable. These references might be best enjoyed by midwestern Americans who grew up in the late 80's/early 90's)
• My Dad Wrote A Porno - 3 people reacting to an "erotica" book series that one of the guys' dad published (I would say the books are maybe only 5%-20% explicit, depending on the chapter) (some of the characters' voices can be annoying/grating, and the narrator tends to repeat sentences after they react to them which can be annoying as well)
• No Such Thing As A Fish - the behind-the-scenes staff of the show QI bring up interesting facts and tidbits from history/nature/etc. (each episode is split into 4 parts where each member brings up a fact and the others react to it and bring up related facts)
• If I Were You - Jake & Amir from CollegeHumor giving advice to listeners (mostly in a sarcastic/tongue-in-cheek way but sometimes genuinely), mostly about relationships/dating
• SmartLess - Jason Bateman and Will Arnett (Arrested Development) and Sean Hayes (Will & Grace) interview a famous person each episode where only one of the hosts known who it is beforehand (it gets better after the first few episodes, though some conversations are less funny/entertaining than others)
• Conan O'Brien Needs A Friend - Conan interviews a famous person each episode (I like the interview part better than the introduction, and similarly to Smartless some conversations are less funny than others)
• If you watched The Office (US) - Office Ladies - Jenna and Angela from the show reacting to each episode of the show and bringing up behind-the-scenes stuff (some of episodes include interviews with other cast members/staff) (might not be as humorous as the others but still fun to listen to)

Pro- the SSD will live longer
Con- the RAM will fill up more, especially when opening resource-heavy pages (though there's a way to unload inactive tabs so that might not be that big of a deal, and especially if you have enough RAM to spare)

Personally I've been using memory-only cache for about a decade (half on HDD, half on SSD) and I don't think I've noticed any adverse effects from that. (though I rarely have more than 5 tabs open at once)

Also, related, is there a way to list communities available from a specific instance? Like if I wanted to see all communities local to Lemmy.world or something (that’s not my local instance), can I do that? If so, how?

Click on Communities at the top of the page, https://lemm.world/communities (make sure the selected tab is Local), though unfortunately it's a paged list and not all communities in one page.

check out https://lemmyverse.net/communities for searching for communities, though not all will show up. You can also use a specific instance to search for communities like - https://lemmy.world/search?q=networking&type=Communities (make sure the All tab is selected)
