There is no download link (usually 'ALL') available if I want to download the Page Info Button extension v0.1.3.1. See https://addons.mozilla.org/de/firefox/editors/review/43023
This problem occurs for all extensions pending review, so something in the last tweo hours broke it.
Erm, ok. This only happens for non-English, so use en-US as a temporary workaround.
I noticed that the platforms are translated for de, which they shouldn't be. (We discovered that translating platforms causes a bunch of problems and restricted that translation to admins, and I think I know of an admin who speaks German!) I cleared those translations, so we'll see if it happens when cache clears in a few hours.
It's fixed now.
