Hi! I’m learning web development from a video and in the video, the guy installs an addon for chrome called HTML5 Outliner. I’m either using Librewolf or Ungoogled Chromium as my main browser, and I can’t seem to install the addon in Ungoogled Chromium. I’m not sure what I’m doing wrong. Is there a setting in Ungoogled Chromium that I need to enable? Anyone know how to bypass this and install the addon?
