Ubufox is broken in Firefox Nightly, due to using no-longer-supported "for each" syntax. Error console now shows "SyntaxError: missing ( after for UpdateNotifier.js:217:8"

I'm using Ubuntu 16.10 with latest Firefox & ubufox.

Package versions:
$ apt-cache show xul-ext-ubufox | grep Version
Version: 3.2-0ubuntu1

$ apt-cache show firefox | grep Version
Version: 50.0.2+build1-0ubuntu0.16.10.1

[CC'ing Alexander, Arzhel/xionox, & Chris, who are all listed as "Contributors" at the top of UpdateNotifier.js, one of the affected JS files. Hoping one of them can address this or might know who can.]

Thanks for reporting this. I'm on vacation now until January, but I'll get this fixed when I return

Great, thanks Chris!

Note: I am not a JS expert, so my suggested replacement in comment 0 might not be exactly right for all cases of this pattern. (I believe it's correct for code that's iterating over a JS array, but the semantics might be slightly different for other structures, e.g. whether you're iterating over keys vs. values, etc. This definitely merits a sanity-check test (e.g. logging each iterated entry before/after the change) to be sure the conversion is valid.)

Hi Chris! I'm still seeing this issue (in latest Firefox Nightly), BTW. I'm also noticing that "about:startpage" (the default homepage imposed by the extension) does not load in affected versions, possibly due to this same issue.

Also: there's one more step that you need to perform before you can test this in Nightly now: you have to set the about:config pref "extensions.allow-non-mpc-extensions" to "true". Otherwise, the Ubuntu Modifications extension will get auto-disabled, as described in https://bugzilla.mozilla.org/show_bug.cgi?id=1364978
