uBlock Origin in PaleMoon 27.x

I had no problem installing this extension in my Win7 Firefox, (and updating my uBlock to the latest version), but on my Win 10 Pro system I am blocked, with the following messages:

"Firefox has prevented this site from installing an unverified add-on." When I click on "more info" link I learn that:

"Add-on signing in Firefox

Add-ons that change your browser's settings without your consent or steal your information have become increasingly common. Some add-ons can add unwanted toolbars or buttons, change your search settings or inject ads into your computer. Firefox will now verify that the add-ons you install have been digitally signed by Mozilla. This article explains the add-on signing feature and how it works."

I didn't have any problem with FF updating uBlock Origin on its own, without needing this separate updater. 

The link I cited above was specifically for a PaleMoon version of the updater.   A FF version --- if needed --- can allegedly be downloaded from  https://github.com/JustOff/ublock0-updater/releases  

My bad.

Got confused between Pale Moon and FF. The latest uBlock Origin version (1.14.22), and updater version (1.3.0) are installed in Pale Moon in Win 10.

Firefox has the latest version of uBlock Origin in Win 10 also. No need for the updater.
