Sep 25/2021, Browser News:
this week marks the 23th anniversary of the Browser News.
The Focus
This focuses on browsers wanted to test websites, e.g. Brave, Chrome, Edge, Firefox, Internet Explorer, Opera, PaleMoon, Safari, SeaMonkey, Vivaldi, Waterfox.
This also focuses on fonts for crafting websites.
There is much good information elsewhere about browsers &fonts, with no need to “reïnvent the wheel”, so this lists news concisely, with links to release notes & other details.

Browser Sniffing
This list userAgents of common browsers, and the browser names, versions, and engines detected by this site
using the cBrowserInfo class:
Browser Engine Sniffing I

Browser Engine Sniffing II

Notes, Warnings, Errors, Ads, Code
This gives samples of similarily styled notes, warnings, errors, ads, and code, preceded by normal text:
Normal Text

A list:

Note: 
some
browsers have userAgent strings which identify them as other browsers: examples are
1 Brave, which identifies itself as Chrome,
2 Vivaldi, which also identifies itself as Chrome,
and 3 the TOR browser, which identifies itself as Firefox.
This makes it impossible for browser sniffers to reliably determine the correct browser name,
though sniffers can still determine the correct engine name.

Warnings
One line warning text
A list of warnings:
- Warning 1
- Warning 2
- Warning 3
Caution: some browsers report major version numbers only; minor version numbers are hidden. For example, 1 Internet Explorer 11.0.140 falsely says that it’s Internet Explorer 11.0, 2 Firefox 94.0.2 falsely says that it’s Firefox 94.0, and 3 Midori 0.5.11 falsely says it’s Midori 0.5. This makes it impossible for browser sniffers to reliably determine the correct browser version vectors.

Errors
One line error text
A list of errors:
- Error 1

- Error 3
Error: 1 some browsers report the wrong version number/vector in their userAgent strings.
For example, Vivaldi 1.15.1147.64 says that it’s 1.96.1147.64. This makes it harder for browser sniffers to reliably determine the correct browser version vectors.
Title: 2 some browsers report the wrong version number/vector in their userAgent strings.
For example, Vivaldi 1.15.1147.64 says that it’s 1.96.1147.64. This makes it harder for browser sniffers to reliably determine the correct browser version vectors.
