It's just giving me a list of 'recommended' addons. How do I find the ones that aren't recommended?
Terrible design, by the way. This was definitely made just to make developers' lives easier.
Fix: I was using an older version by mistake. Updating shows the option to get more addons than just the recommended ones at the bottom.
Kind of weird it wasn't included for awhile.
Not sure what's causing the UI issues but another way to go about this is to create a custom collection and configure your browser to use it. This way you can control what shows up in "recommended". IIRC you have to use nightly, beta or a custom build like Fennec to allow using a custom collection.
