Right now Firefox for Android does not support Intl.Segmenter [1] but it appears that support has been added to nightly [2] and will be released soon!

Sorry about that. I was weighing the pro/con of waiting for support to be released or adding a polyfill but it seems that support is just around the corner from what I can tell from the issue.

I see, thanks for investigating! I guess it must be a relatively new API, seeing how recently Safari has implement it.

Looks like a very good API, glad to have learned about it!

It shipped in Safari nearly 3 years ago [1] so it’s not that new.
