Despite what the threads I read say, Discourse does not support UXP browsers and it’s forks like Pale Moon, Basilisk, etc… Any idea why or how this can be fixed? Does not get fixed when spoofing as Firefox in User Agent either. [Screenshot 2026-05-27 at 02.18.35] Pale Moon is not an old browser before you ask, it is a regularly maintained and up-to-date browser.

hi there :wave: welcome :slight_smile: from What is Discourse? | Discourse - Civilized Discussion) [image] this has also been discussed before here: Discourse is incompatible with Palemoon web browser (and older Firefox)

Is there anything Pale Moon can do to meet these guidelines? I’m happy to oblige to implement any missing JavaScript/CSS.

If it’s your own forum, this plugin might help: [изображение] Dumbcourse – Old-browser friendly UI at /dumb (D-pad + small screens) Plugin information_source Summary Dumbcourse adds a lightweight, old-browser friendly Discourse UI under /dumb, designed for D-pad navigation, small screens, and older Android WebViews where the standard Discourse UI can be too heavy. hammer_and_wrench Repository Link https://github.com/TripleU613/dumbcourse open_book Install Guide How to install plugins in Discourse This project was made possible with the work of @ars18: The original project uses a Cloudflare worker proxy…

If you open the browser developer console, you should see a log of the failed JS/CSS feature-detections.

Will take a look at it. Thanks. :+1:
