Thanks for the report. I tested subscription links on Firefox 141.0.3 (Windows 11) and they work correctly with this test link: https://ublacklist.github.io/rulesets/subscribe?url=https%3A%2F%2Fraw.githubusercontent.com%2Fusername%2Frepository%2Fmaster%2Fublacklist.txt

Could you please:

1. Share the specific subscription link you tested
2. Test with official Firefox for Android (not just IronFox) to rule out fork-specific issues

Oh, that one does seem to work.

I've been trying the one from the Huge AI blocklist: https://iorate.github.io/ublacklist/subscribe?name=Main+AI+Blocklist&url=https://raw.githubusercontent.com/laylavish/uBlockOrigin-HUGE-AI-Blocklist/main/list_uBlacklist.txt

This link works in Chromium but not Firefox

The list itself also notes this: https://github.com/laylavish/uBlockOrigin-HUGE-AI-Blocklist?tab=readme-ov-file#installing-it-with-ublacklist

The link I shared also does not work in Firefox Android as you requested to test

Thanks for the details. The link you're using (https://iorate.github.io/ublacklist/subscribe?...) is the old format introduced in v6 that only works in Chromium-based browsers. The old format is kept for backward compatibility but has browser limitations, though it has the advantage of not requiring host permissions. The new format (https://ublacklist.github.io/rulesets/subscribe?...) should work in both Firefox and Chromium.

Oh! Thanks for letting me know.
