This new proposal means that the nightly Firefox builds will be compatible with the vast majority of add-ons available right now. Users will still have to disable the compatibility check to use the add-ons though (something users have been doing to get add-ons working with the latest stable versions of the browser before developers have updated them). Add-ons that are hosted on Mozilla’s website will be automatically tested on the nightly Firefox builds and will be marked as compatible unless a problem is discovered.
The new add-on rules won’t take effect immediately, but it was mentioned that Aurora users won’t be able to make use of the add-ons until the next six-week cycle begins. This is also great news for add-on developers who want to work on their add-ons with test Firefox builds before the stable version of the browser is released. How many of you Firefox Aurora users are excited by this news?
