User Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:24.0) Gecko/20100101 Firefox/24.0 (Beta/Release) Build ID: 20130910160258 Steps to reproduce: When using the french keyboard layout, type a sentence and end it by a space followed by an exclamation or question mark. Actual results: The space before the exclamation or question mark gets deleted. Expected results: The space shouldn't be removed. Even better, if there is no space, it should be added. In fact, the french rule is different than the english one: double punctuation signs (i.e. "?", "!" and ";") must be preceded by a non-breaking space.

Confirmed, source: http://french.about.com/library/writing/bl-punctuation.htm. Anyway, I'd be happy to accept a patch for it. Don't think we would triage it with high prio before we launch FxOS in a French speaking country.

OK, maybe someday I'll find the courage to set up a dev environment and patch it!
