I’ll counter and say that it’s culture/conditions-based. Humans have a range of available/possible behaviors/thought patterns and they are reinforced/shaped by their surroundings/the system they live in. There are and have been egalitarian societies that aren’t full of “mean, stupid, and crazy” people.

“The idea that the key features of successive societies and human history have been a result of an ‘unchanging’ human nature […] is a prejudice that pervades academic writing, mainstream journalism and popular culture alike. Human beings, we are told, have always been greedy, competitive and aggressive, and that explains horrors like war, exploitation, slavery and the oppression of women. This ‘caveman’ image is meant to explain the bloodletting on the Western Front in one world war and the Holocaust in the other. I argue very differently. ‘Human nature’ as we know it today is a product of our history, not its cause. Our history has involved the moulding of different human natures, each displacing the one that went before through great economic, political and ideological battles.”

“The world as we enter the 21st century is one of greed, of gross inequalities between rich and poor, of racist and national chauvinist prejudice, of barbarous practices and horrific wars. It is very easy to believe that this is what things have always been like and that, therefore, they can be no different. […] The anthropologist Richard Lee [said]: “Before the rise of the state and the entrenchment of social inequality, people lived for millennia in small-scale kin-based social groups, in which the core institutions of economic life included collective or common ownership of land and resources, generalised reciprocity in the distribution of food, and relatively egalitarian political relations.” In other words, people shared with and helped each other, with no rulers and no ruled, no rich and no poor. […] Our species […] is over 100,000 years old. For 95 percent of this time it has not been characterised at all by many of the forms of behaviour ascribed to ‘human nature’ today. There is nothing built into our biology that makes present day societies the way they are. Our predicament as we face a new millennium cannot be blamed on it.”

edit: some books that are on my TBR that might be worth checking out:

• Just Babies: The Origins of Good and Evil
• Hope for Cynics: The Surprising Science of Human Goodness
• The Social Instinct: How Cooperation Shaped the World
• Out of the Wreckage: A New Politics for an Age of Crisis (“shows how new findings in psychology, neuroscience and evolutionary biology cast human nature in a radically different as the supreme altruists and cooperators.”)

Right, though I believe that when you unload a tab it stays there? With the snooze thing it closes the tab and reopens later

It opens it again as a new/refreshed tab, though it does it automatically at the postponed time and so it’s more convenient than having to do it manually (especially when you snooze several tabs)

It’s not for saving memory but to postpone a tab to check it later (for example to see new comments on a post, or if you don’t currently have time to read an article and want to read it tomorrow)

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

Domain Volume Control / Better Volume Booster - allow you to set default volume per-domain (note that unfortunately, in the 1st one the set volume gets changed when you change the volume through a site’s player, and the 2nd one currently causes an issue on Nightly with unpaused videos)

Playback speed - allows you to change the speed of videos/audio on any site, even only by x0.01 at a time (you can also change the buttons that appear when you click on the addon in the toolbar/addons menu to have specific speeds readily available) (note that it doesn’t change the pitch of the audio)

• Specifically for YouTube you can also use an addon like Improve YouTube. To configure the feature click on the addon in the toolbar/addons menu > Shortcuts > Playback speed. To change the shortcut so that you hold Ctrl and use the mousewheel (while hovering over the video) click Ctrl and release it before using the mousewheel up or down accordingly (otherwise it acts as a zoom to the settings window)

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

I’ve been using this site to convert to PDF for forever, so I’m assuming it’ll also be good for the other way around
