I just tried it on Android Firefox, and well, it does work, but you can definitely tell that it wasn’t built for Android Firefox.
It doesn’t show up in the URL bar and rather just in the extension menu. In there, it still gets hidden when no RSS feed is available. It copies to the clipboard as expected. And when there’s multiple feeds, it opens a separate page to show the dropdown in a very small font. Definitely usable enough, since you’re not going to interact with it all the time, but I wouldn’t give it the same glowing review…









From the bug report:
According to Wikipedia, the browser was already renamed to “Firefox” when that bug report was opened, but still wild to see that even back then, they already had some technical debt for the name of that directory.
Unfortunate that they did not go straight from
~/.phoenixto$XDG_CONFIG_HOME/mozilla, but hard to say, if that was as obvious of a choice back then…
