Based on the details provided on the AMO site, ifamebook would work on Firefox 26.0, that you are using on Android.

Version 3.95 Released June 12, 2013 761.6 KB Works with Firefox 11.0 and later

Also, as per the site, this is for Firefox only. To confirm, this is the Addon you are talking about, right? https://addons.mozilla.org/en-US/firefox/addon/ifamebook/

That link is for the desktop Firefox and not the Firefox for Android. It would say "Works with Firefox for Android" if it was compatible for Android version.

The author does not appear to have a version for Android. https://addons.mozilla.org/en-US/android/search/?q=iFamebook&appver=&platform=
