Only recently, I learned this works on just about any web-browser:
Ctrl-9 (macOS: Command-9) goes to LAST tabCtrl-1 (macOS: Command-1) goes go FIRST tabVia: [WayBack] Switch Between Tabs in Any Browser Using Shortcut Keys
For those keyboard ninjas who hate using the mouse, switching between tabs in your browser window is essential since most people probably have a bunch of tabs open at once. […]
…
If you want to go to a specific tab, you can press CTRL + N, where N is a number between 1 and 8. Unfortunately, you can’t go past 8, so if you have more than eight tabs, you’ll have to use a different keyboard shortcut or just click on it. CTRL + 9 will take you to the last tab, even if there are more than 8!

For my link archive: [WayBack] browser – How to connect a website has only IPv6 address without domain name? – Super User (thanks haimg):
According to RFC2732, literal IPv6 addresses should be put inside square brackets in URLs, e.g. like this:
If you also need to specify a port other then 80 to access the server it has to be placed after the closing bracket:
Of course, you have to have end-to-end IPv6 connectivity to that host. E.g. if the server is not inside your own local network, you need to have IPv6 connectivity, either via your ISP (rare), or via some kind of IPv6 in IPv4 encapsulation (tunnel).

Just in case it’s not enabled yet: How to enable JavaScript in your browser and why
It even has some html to redirect to it, which I’ve replaced with the wayback machine (and put into a gist as WordPress kills noscript tag blocks and everything they contain.

I needed it as at a client site, one of the embedded devices would show the message “Javascript is required to use this web portal” in various web browsers so I had to check the JavaScript status in each browser.

A while ago I suspected at least one of my Chrome extensions to do funny things.
In the end it appeared that “Live HTTP Headers 1.0.8” went rogue a while ago and has by now been removed from the store as this link is gone: https://chrome.google.com/webstore/detail/iaiioopjkcekapmldfgbebdclcnpgnlo ()
It was part of a much larger set of extensions that went away and isn’t limited to Chrome: other browsers with extension mechanisms suffer from this too. More links about this at the bottom of this post.
Which means that by now you should be really careful which extensions you have installed and enabled.
So, browse through these and ensure you’ve disabled everything you don’t need permanently:
On my system, I removed these:
When you go from Chrome to these URLs through the extensions page, it usually appends an UTM tracker like utm_source to the URL.
So I dug into that as well and found these links explaining them:
