@Rumyra, @ddbeck The two last messages are spam. (I cannot hide them, I don't have the rights here)

Firefox fully supports entry.contentBoxSize only since version 92 (September 2021), so we need to decide whether that's long enough to remove the fallbacks for older Firefox versions:

dom-examples/resize-observer/resize-observer-text.html

Lines 83 to 91 in df1f3a0

 // The standard makes contentBoxSize an array... 
 if (entry.contentBoxSize[0]) { 
   h1Elem.style.fontSize = Math.max(1.5, entry.contentBoxSize[0].inlineSize/200) + 'rem'; 
   pElem.style.fontSize = Math.max(1, entry.contentBoxSize[0].inlineSize/600) + 'rem'; 
 } else { 
   // ...but old versions of Firefox treat it as a single item 
   h1Elem.style.fontSize = Math.max(1.5, entry.contentBoxSize.inlineSize/200) + 'rem'; 
   pElem.style.fontSize = Math.max(1, entry.contentBoxSize.inlineSize/600) + 'rem'; 
 } 

dom-examples/resize-observer/resize-observer-border-radius.html

Lines 33 to 40 in df1f3a0

 if (entry.contentBoxSize[0]) { 
   entry.target.style.borderRadius = Math.min(100, (entry.contentBoxSize[0].inlineSize/10) + 
                                                   (entry.contentBoxSize[0].blockSize/10)) + 'px'; 
 } else { 
   // ...but old versions of Firefox treat it as a single item 
   entry.target.style.borderRadius = Math.min(100, (entry.contentBoxSize.inlineSize/10) + 
                                                   (entry.contentBoxSize.blockSize/10)) + 'px'; 
 }

Hello @ideagay, both versions exist to ensure backward compatibility. We'd need discuss separately when to remove the older version. However, Since there is no bug in the documented code, I am closing this issue.

Please feel free to reach out to us and our community with any questions on our Discord server. Thanks for using MDN!
