Which is missing nearly all of the addons that I use and which don't seem to be a priority for Mozilla. Their whole strategy regarding addons is incredibly frustrating.
They are opening it up, just taking time as they are developing the appropriate API points. This is a complete rewrite, going to take awhile before all the same API is available. They have opened some major addons as they are tested and stable.
I agree that the lack of full support for add-ons is frustrating, but the alternative you end up going back to, Brave, doesn't (seem to) support add-ons at all. How is that better?
Because using Firefox nightly would signal to Mozilla that I'm fine with how they're handling add-ons. If they're not going to support add-ons properly, I'm not going to use their browser.
I'm not okay with how Mozilla behaves regarding add-ons. As in, they have all this addon support, but it's not in any way a priority for them so they've basically taken it all away. So I won't support them or use their browser until they do.
