Google Chrome Portable 64-bit Stable (Test) 73 (latest version offered by PortableApps.com) isn't manually updating extensions

So dev mode is already enabled in the extensions page and when I click on "Atualizar" ("Update" in English), all I get is a message in the bottom left corner of the screen with the text "Atualizando..." ("Updating...") that never goes away (unless I close the tab and open it again). But the outdated extensions don't get updated by this way. I know because today there was released a new version of "The Great Suspender" extension and on my Chrome it still didn't get the update although I'm trying to manually update.
