I updated to the latest 62.0~b6+build1-0ubuntu0.18.04.1 amd64 on my xubuntu, but then I saw Ublock Origin disabled in the add-on menu. I tried to get it back, downloaded a xpi via Chromium, but this error kept coming back. And it's not only Ublock Origin, any other add-on gives the same error. I deleted the extension* files using Troubleshooting - did not help at all
