Google's Favicon Guidelines for Search Results
Jamie Leach reports: Google Search now displays favicons on mobile search results. Optimal favicon size should be a multiple of 48x48 pixels (Google will resize to 16x16). Websites lacking a favicon, or with inappropriate ones, will show a default globe icon.
Your favicon should clearly represent your website's brand to aid user identification in search results.
Interestingly, even top websites show inconsistency in icon declaration (using <link> tags). Examples like Twitter and Pinterest, despite being modern PWAs, only offer icons in limited sizes:
<link href="/icon-32x32.png" rel="icon"><link href="/icon-192x192.png" rel="apple-touch-icon">

The Paciello Group announces: The ARC Toolkit, a professional-grade accessibility testing tool, is now a Chrome DevTools extension. It identifies WCAG 2.1 guideline violations, testable on entire pages or selected nodes within DevTools.
Remember: automated tools only detect some accessibility issues; manual testing remains crucial for comprehensive accessibility. Lighthouse (in the Audits panel) recommends manual checks post-audit.

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages.
