Why You Should Always Test your Add-on With Other Add-ons
Alternate Title: Personas 1.6 Breaks Add-ons
In the past couple weeks, we’ve started getting reports of Brand Thunder add-ons breaking. The problems range from display problems, to hangs, to the inability to bring up the add-ons manager. Of course, when you are the last add-on to be installed, you generally get the blame. After some investigating, we came across bug 590608. In case the summary isn’t clear:
Personas 1.6 breaks hundreds of add-ons.
And they didn’t just break add-ons. They broke the extension manager. Which means they most likely broke the ability for the broken add-on to be blocklisted. And at least a million people got this update before it was put in the sandbox.
