It seems I can still sideload add-on in the Nightly Firefox 74.0a1, but Mozilla blog says it will stop supporting sideloading
I installed Nightly Firefox 74.0a1 and I am still able to sideload extension. But based on this article https://blog.mozilla.org/addons/2019/10/31/firefox-to-discontinue-sideloaded-extensions/, sideloading will not be supported in Firefox 74. I tested both of sideloading methods (https://extensionworkshop.com/documentation/publish/distribute-sideloading/?utm_source=blog.mozilla.org&utm_medium=post&utm_campaign=2019-sideloaded-discontinued) and the extension was able to be sideloaded successfully in both ways. Does anyone know the reason?

What do you consider to be sideloading? The blog post has a rather specific and narrow definition, from what i see.
Also, the fact that something is due in a particular version of FF does not mean that the code is baked into the alpha builds yet.
From what location(s) are you installing the extensions ?
This is only about globally installing extensions from specific directories. You should still be able to install all extensions. Firefox 73 would copy extensions installed in these directories to the current profile folder according to the blog post.
Did you check the extensions folder in the profile folder in Firefox 74 ?
