I originally wrote IPvFoo for Chrome in 2011, to observe whether websites are served using IPv4 or IPv6:

In 2017, Firefox added initial WebExtensions support, so I dropped the extension on addons.mozilla.org, technically functional but full of bugs, and hoped for the best.
This week, I finally sat down with Firefox and ironed out all the problems:
- Added a separate
manifest.jsonthat uses “scripts”, as Firefox Manifest V3 doesn’t support “service_worker” - Added a button to grant webRequest permissions, as Firefox Manifest V3 doesn’t do this automatically
- Hacked the popup dialog to avoid unnecessary scrollbars
- Added an in-RAM hostname-to-IP cache, as Firefox doesn’t remember the IP address of cached requests
- Examined
details.documentUrlwhen handling requests from a Service Worker, as Firefox doesn’t usedetails.initiator
I’m pretty sure that covers everything, so IPvFoo now provides an equivalent user experience on Chrome and Firefox. Enjoy!

Is that for mobile as well?
https://blog.mozilla.org/addons/2023/08/10/prepare-your-firefox-desktop-extension-for-the-upcoming-android-release/I’m trying to de-google myself and really enjoying Firefox on Android (replacing chrome on desktop has some performance kinks for me).
Is it unavailable for my android browser because Firefox hasn’t released the update yet? Or is it not compatible?Update: IPvFoo is now working on Firefox Nightly 120 for Android.
