I use double-click highlighting, and the reason is mostly selecting passages of text when editing. Double-click highlighting makes it so I don't have to find the precise character boundaries for the first and last words in the passage. Instead, I can just double click the first word, roughly move my mouse to hover over the last, and copy or delete that entire passage.

Firefox's approach is fairly useless in this regard. Even if it's predictable from a technical perspective, it's not predictable for a reader who naturally processes semantic breaks rather than technical ones. Unlike in English, where a space is both semantic and visual, hiragana-kanji boundaries often don't mean anything. As a result, for me at least, Firefox's breaks feel a lot more random than Chrome's, which, while dodgy, are often fine.

Having used Firefox as my main browser since 2006, I remember when I discovered this feature in Chrome, and being shocked at how much of an effect that minor improvement had for me. It's not a deal-breaker, certainly, but it's become my one big annoyance with Firefox.
