Can not install a signed addon on version 50.0b2
When I try to install an officially signed add-on by dragging and dropping it into the browser, Firefox prompts that the file is corrupted. However, when I directly copy the file to the browser/extensions directory, the browser disables the add-on as untrusted. How can I properly install a signed extension in Firefox version 50.0b2? I can confirm that the extension works correctly when temporarily loaded (via temporary installation), but it fails to install after being officially signed.

Didn't you get the memo?
Update Firefox to prevent add-ons issues from root certificate expiration

I understand that, but the browsers are on enterprise clients' machines. I can't directly upgrade their browsers, and many of their business-critical functionalities rely on this older Firefox version. If an upgrade causes issues, my boss would kill me. Therefore, I need a way to install the add-on on the legacy Firefox version without upgrading it.
As a developer I totally understand the stress of upgrading things, but we don't have any solution for this case.
Does this extension have an older version, from before year 2020? It could work.
Unfortunately, it doesn't. Maybe I need to make it compatible with versions before 2020, but I don't know if it can still be signed. Haha
