Just adding that as I understand this, donations to the Mozilla Foundation cannot go towards Firefox, because it's [edit: Firefox is] actually part of the Mozilla Corporation. To help with funding Firefox people can consider purchasing the Corporation's other products (VPN/Relay/Monitor), or purchasing merch.

Tab Snooze - allows you to close a tab and have it reappear at a chosen time later

Media URL Timestamper - automatically inserts the current timestamp of the YouTube/Twitch video you're watching and updates it in the history in case you accidentally close/navigate away from the page or go to a different time in the video

Feedbro - RSS reader with filtering capabilities

Redirector - auto-redirect specific URLs (for example, changing a YouTube Shorts url into a regular one, or changing Reddit links to always go to Old Reddit)

Undo Close Tab Button - allows you to restore recently closed tabs including the tab's history in the back button (max amount = browser.sessionstore.max_tabs_undo)

Violentmonkey - using userscripts that allow you to change things on websites.

• For Instagram - unmuting videos + setting their default volume
• For YouTube - disabling the subtitles/captions + disabling "autoplay next" for playlists + disabling autoplay of channels homepage video
  • a way to disable specific keyboard shortcuts (you need to manually add the code as a new script). I use /^(Key)?(End|I|O)|(Digit|Numpad)\d$/ instead of /^(?:Digit|Numpad)\d$/ (thanks to this post), to also disable the End/I/O keys in addition to the number keys.
• Note that, at least for Violentmonkey, if the userscript doesn't have the "://" part of the url in the @match line then you need to add it in the userscript settings after installing the script (for example, if the @match line of the script only has *.youtube.com/* then put *://*.youtube.com/* in the "@match rules" line in the settings)

YouTube Comment Reader - allows you to search through the comments of a video (by clicking on the addon in the Extension menu and then clicking on the "YouTube Comment Reader" at the top or the "X Comments" at the bottom of the tooltip)

Page Shadow - allows you to use dark and light themes on sites that don't have the option to change it.

And if you're like me and you find that some YT videos feel too slow but 1.25x is too fast, then you can use Enhancer for YouTube's "Playback speed" feature to have smaller speed steps. Then you can hold ctrl and use the scrollwheel (while over the video) to change the video's speed by the amount you chose (I use 0.05 speed variation, mostly changing to 1.05x or 1.10x)

a kindergarten-level understanding of German.

I love the serendipitous use of kindergarten, with it being of German origin :)

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 overall being funny/silly
• 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)
• Office Ladies - Jenna and Angela from The Office (US) reacting to each episode of the show and bringing up behind-the-scenes stuff (some of episodes include interviews with other cast members/staff)

To add and reiterate what others have said:

• It's similar to following sports and knowing all the game results, who's injured/out for the season, etc.
• People like to feel part of larger society/culture, and to feel knowledgeable, to feel "in on things"
• It's a way to fill time/fill the void, a distraction from "real life" which can leave you feeling powerless/drained
• It can be a good conversation topic with friends when there's not much to talk about (or when other topics can be contentious)

Not sure if they all fit entirely but:

• The Story Of Stuff (Annie Leonard)
• How The World Works (Noam Chomsky)
• Predictably Irrational: The Hidden Forces That Shape Our Decisions (Dan Ariely)
• The Hidden Brain (Shankar Vedantam) / Idiot Brain (Dean Burnett)
• The Myth Of Choice (Kent Greenfield) / The Paradox Of Choice (Barry Schwartz)
• The Free Will Delusion: How We Settled For The Illusion Of Morality (James B. Miles)
• Getting Free: Creating An Association Of Democratic Autonomous Neighborhoods (James Herod)
• The Best That Money Can't Buy (Jacque Fresco)
• No Contest: The Case Against Competition (Alfie Kohn)

I fear that this will be used as a pretense to have a Real ID tied to all of your online accounts, and that it will be publicly facing.

And then if people come to your house after you share a wrongthink, or if part of who you are clashes with "the good ole days", well then that's just an unintended but necessary evil, so sit down and shut up.

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)

just making sure you've seen this nested comment

On the comedy side like MBMBAM:

• 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)

• Office Ladies - Jenna and Angela from The Office (US) reacting to each episode of the show and bringing up behind-the-scenes stuff (some of episodes include interviews with other cast members/staff)
• 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)

The pressure to review thousands of horrific videos each day – beheadings, child abuse, torture – takes a devastating toll on our mental health

What could be a solution for dealing with that? I wouldn't want to be exposed to that type of content even if I was paid to do so and had access to health support to deal with the aftermath every time.

Copying the profile folder should do it

You should also copy profiles.ini (which indicates the path of the working/available profiles)

Generally speaking, this should also work for other forks, but it might depend on which versions the forks are based on. If they are too behind the version that the profile is from then there might be "forwards compatibility" issues, for example in the way specific files/databases are structured (but maybe not, this is just a guess).

Also note that since forks tend to have different default values for some settings then if you didn't explicitly set them through a user.js file or directly in prefs.js (or another method) then you would get the default from the fork instead of the one from the main version.

Yes, it will copy everything related to that profile. The passwords are stored in the key4.db file so it shouldn't be copied in that situation.

https://support.mozilla.org/en-US/kb/profiles-where-firefox-stores-user-data#w_what-information-is-stored-in-my-profile

Then there's also the sync feature which might import the passwords even if the file has been deleted, so the sync needs to be disabled on the work pc.

Israel Kamakawiwo'ole - Somewhere Over The Rainbow

Shawn Colvin - I'll Be Back

Sonic Youth - Superstar (btw not originally by The Carpenters)

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.
• Try not to sleep for more than 8 hours so you'll need the sleep the next night.
• 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 (fan/air purifier/etc.)
• 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)

For the more advanced, you can also mess around with the userChrome.css file. To create it open a text editor and save the file as userChrome.css in the \Chrome folder in your Firefox profile folder* (make sure to restart Firefox to apply the changes)

To enable the file, enter about:config in the address bar, then accept the warning if it appears. Search for toolkit.legacyUserProfileCustomizations.stylesheets and double-click it to set it to true.

*enter about:support in the address bar, or click on the Help menu > More Troubleshooting Information, then scroll to the Profile Folder line and click on Open Folder. Usually it's C:\Users\~USERNAME~\AppData\Roaming\Mozilla\Firefox\Profiles\~PROFILENAME~

*Note: the first 2 lines about tab height might not work if you don't have the Playing/Muted text line in tabs disabled. To disable that line go to about:config, search for browser.tabs.secondaryTextUnsupportedLocales, and add ,en (or the relevant language that you're using in your system) at the end of the value for it then click Enter and restart Firefox to apply the change.

I've been using it for a few months and it's been great, but I just found out that by default it injects itself into all processes and it gave me the ick (for example if you use Firefox you can see in about:third-party)

The explanation provided seems kinda logical but I don't know if it's legit or not

I remember hearing about a similar experiment from the 70's in Canada
