How to disable extension compatibility checking on Nightly builds of Firefox

A long long time ago (I can still remember…) we changed the preference you use to disable compatibility checking for extensions. We still aim for users to instead use tools like the Add-on Compatibility Reporter to handle this (especially since we are going to start crowdsourcing data from it), but for developers who don’t want to install that but still want to use extensions on their nightly builds the new rapid release model would mean setting a new preference every 6 weeks.

We’ve now changed this and any nightly, try, or self-made builds (anything not on the aurora, beta or release channels) will instead use the single preference extensions.checkCompatibility.nightly from now on, regardless of version. This will be available from tonight’s nightly onwards.
