RSS Preview even on latest Android version
After some reinstalls via the older version to have RSS html feed at least temporarily I seem to have it permanently now in the updated version
I installed the version 68.11.0 via apk file last month several times thosedays when I needed the RSS feed on my mobile within Firefox. When it auto-updated itself I uninstalled it and reinstalled the old version.
Although it is listed as not supported and inactive add on it works with every xml rss feed. Maybe someone can replicate and explain how this works. I would love to have this "feature" on my new android as well but it did not work like on the old one.
