Per the article, uBlock Origin is still in the Firefox store at https://addons.mozilla.org/en-US/firefox/addon/ublock-origin... ; it's the lighter MV3-based uBlock Origin Lite that was removed. So the general population can continue to use the full Origin.

And because the original non-lite uBlock Origin supports much more complicated rulesets, it should be effective even without code updates... but it still is concerning that the same Mozilla errors that caused Origin Lite to be flagged might extend to time-sensitive updates to the original Origin as well.
