A cool way to unit-test JavaScript code on the browser side is [Wayback/Archive] Getting Started | QUnit:
To get started with QUnit in the browser, create a simple HTML file called test.html and include the following markup:
<!DOCTYPE html>
<meta charset="utf-8">
<title>Test Suite</title>
<link rel="stylesheet" href="https://code.jquery.com/qunit/qunit-2.19.4.css">
<body>
<div id="qunit"></div>
<div id="qunit-fixture"></div>
<script src="https://code.jquery.com/qunit/qunit-2.19.4.js"></script>
</body>
That’s all the markup you need to start writing tests. Note that this loads the library from the jQuery CDN.
I was so glad to find QUnit via the below links as I unconsciously wanted such a thing for a very very long time.
You can either run it locally or remotely or from the jQuery CDN as both it
- is a Node.js module so the source files are all available on the jQuery CDN
- it does not require the Node.js to load so it can run from any location you want (that CDN, locally or another on-line location)

On Firefox, taking a screenshot is just a shortcut away [Wayback/Archive] Take screenshots in Firefox | Firefox Help:
Ctrl + Shift + S on Windows/Linux/Chrome OSCommand + Shift + S on MacOS
Too bad Mozilla also appears to be amongst the bad guys in firing an employee having cancer ¹.
On Chrome not so much and require opening the Chrome Developer Tools which take up precious screen estate, and saves the screenshot in the downloads folder instead of the clipboard. Many guides exist, for instance:

It looks like I missed that Google has added a new URL parameter to its search engine quite a while ago.
In the past, you could turn on image search using the tbm=isch URL parameter (“to be matched” and “image search”).
That still works, but there is a new parameter on the block that is officially undocumented, and can be used to switch into various search modes including image search but also AI-less search.
This drastically lowers the carbon footprint and also gets you far less speculative information.
Edit 20251023: I forgot to save the below part before the scheduled post got published. So here we go

I tried these:
- 3.7 stars [Wayback/Archive] Cookie Manager – Get this Extension for 🦊 Firefox (en-US)
- 4.4 stars [Wayback/Archive] Cookie Quick Manager – Get this Extension for 🦊 Firefox (en-US)
For me, the last works best and has its configuration page at moz-extension://4ea87baa-23b8-4b4a-bd88-7a6bc4b8e442/cookies.html?parent_url=
The first starts with an intimidating query screen without clear indication on what each query option means nor how to perform deletes on the returned cookies.
I did not yet try 4.2 stars [Wayback/Archive] Cookie-Editor – Get this Extension for 🦊 Firefox (en-US)
Query: [Wayback/Archive] firefox cookie manager – Google Suche
Note: my usual starting point is moz-extension://4ea87baa-23b8-4b4a-bd88-7a6bc4b8e442/cookies.html?parent_url=https%3A%2F%2Fweb.archive.org%2Fweb%2F*%2F as that will select cookies on web.archive.org where lots of archived sites pollute that domain with cookies. This inevitably causes the Wayback Machine save page to error out.

Many web-sites and password managers have a strength indicator built-in.
This is a really good example (with open source JavaScript code!) of one: [Wayback/Archive] zxcvbn: Low-Budget Password Strength Estimation | USENIX
Be aware though that it stores a plain text file named passwords.txt on your system (this seems to confuse some users, especially when their password is in it).
Homans password behaviour does not change much over time, so this half hour 2016 presentation on it is still current: [Wayback/Archive] USENIX Security ’16 – zxcvbn: Low-Budget Password Strength Estimation – YouTube for which you can download:

Trying to trim down excessive CPU usage of my web browsers, and lessen the risk of intrusion, I experimented with globally disabling JavaScript and only enabling it on sites where it adds value to me.
That is possible (see below), but immediately showed a big side effect: Bookmarklets will not work on sites that have JavaScript disabled.
Disabling JavaScript globally only allows Bookmarklets on sites where you have enabled JavaScript. Not the situation I hoped for (:
I’ll try it for a while though.

A few years back I bumped in this cool [Wayback/Archive] Thread by @asadotzler on Thread Reader App on early Firefox history (from before it was called Phoenix or Firebird, heck from before Phoenix was created!).
It is important to keep telling these bits of history as they are fundamental to understand the Web Browser landscape as it is now.
Great material that complements Wikipedia articles like these:
