I have LINGUAS="en_CA fr_CA en fr" and no english locale was installed. (I guess en_US needs to be included too).
hmm, it seems that there is no .xp file for en_US

In what language did it show up?
In make.conf I have LINGUAS="en ja en_US", and after the bump to 3.5 my Firefox is very much in Japanese. This was not the case with release candidates or betas from the mozilla overlay; if memory serves, those had linguas_en (and/or _en_US, I don't recall) in IUSE as well. At any rate, I can confirm this bug, although it's good reading practice I suppose =).
So it seems that if any "other" language XPI is installed, Firefox shows up in that language instead of in English...
are there any workarounds yet, or are we forced to re-emerge firefox without any linguas?
A workaround for those who (like me) aren't yet 100% in language #2: Browse to about:config and set general.useragent.locale to en-US (or the like), then restart Firefox. This applies per-profile.
This issue has (likely) been fixed with -r1, please upgrade and reopen if that's not the case.
