Status: RESOLVED DUPLICATE of bug 1557291

(Core :: Layout: Text and Fonts, defect)

Attachment: 20180821-hyphenation-german-firefox-68-broken.jpg

User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_13_6) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/76.0.3809.100 Safari/537.36

Steps to reproduce:

I noticed that a hyphenation polyfill we use is surprisingly activating in current Firefox after its feature detection determines that Firefox does not support CSS hyphens support for German.

I have built a tiny test case with German words that should be hyphenated via CSS hyphens: auto; here: https://codepen.io/polarbirke/pen/JjPRgqr.

I could verify that the test case works correctly in the (outdated) Firefox 64.0a1 Nightly I have installed (see attachment), so this looks like a regression.

Actual results:

Firefox 68.0.2 does not hyphenate words like "Silbentrennung" or "Deutschland".

Expected results:

The words should have been hyphenated (see attachment).

It happens only on Uppercase words, and it's fixed in 69. In the meantime, you can work around by adding a boolean pref intl.hyphenate-capitalized.de set to true in about:config.

Thanks for the heads-up!
