Add-on Compatibility for Firefox 47

Firefox 47 will be released on June 7th. Here’s the list of changes that went into this version that can affect add-on compatibility. There is more information available in Firefox 47 for Developers, so you should also give it a look.





Let me know in the comments if there’s anything missing or incorrect on these lists. If your add-on breaks on Firefox 47, I’d like to know.

The automatic compatibility validation and upgrade for add-ons on AMO will happen in a few weeks, so keep an eye on your email if you have an add-on listed on our site with its compatibility set to Firefox 46.

    alguna dirección de correo donde te pueda contactar para preguntarte sobre el add-on Remote-XUL-Manager y su uso desde firefox montado en Citrix, para automatizar la lista de URL configuradas en él y que para los usuarios sea transparante, es decir, que ellos no tengan nada que configurar.

    Hasta ahora hemos podido hacer que el plug-in esté instalado automáticamente, pero no hemos podido automatizar la lista de URL

    Hi Jorge,

    One of our widely-used extension has been broken by Firefox 46 release. Our main developper is now on the other side of the Great Firewall, so I need to fix it myself.

    I identified and fixed one of the problem (due to legacy array comprehension syntax), but there seems to be other ones. Is there a place where I could get help or advices?
