how to side-load

[quaz...@gmail.com]

What is the preferred method for side-loading a webextension?
I see in ...
https://developer.mozilla.org/en-US/Add-ons/Distribution
... that it can be done but there are no instructions how.

Registry key?
Place .xpi in a certain directory?
Execute Firefox with a certain command-line option?
Some other?

Thanks in advance.

Found this ...
https://developer.mozilla.org/en-US/Add-ons/Extension_Packaging
... but I think it is mostly outdated.
the USING THE REGISTRY link goes to an archive of obsolete content.
and putting the xpi in the extensions directory didn't work.

I think this is the one you want:
