That's really odd. Did you file a bug for that? If not, please do, and share the link!
Is this happening in the addon installation process or "regular" file download? If the first, did you try right click -> save as to download the XPI and open it in Fx after the download has finished? _______________________________________________ dev-b2g mailing list dev-b2g@lists.mozilla.org https://lists.mozilla.org/listinfo/dev-b2g
