Compared to en-US, Czech Firefox for Android is missing any feed reader. On the other hand, Yahoo mail for mailto is there. Firefox for Android should follow Firefox for desktop and have Seznam as feed reader and first mailto as well.
Bug 1210092 has been de-prioritized, and I don't think we should wait here anymore. Michal, do you like to look at it and practice hg patches and review requests a bit? I would guide you through it of course.

I have tried to check the behavior in Nightly when accessing RSS feed or mailto link, but seems it offers only installed applications on my phone. So is there any use of localizing the handlers?
(In reply to Michal Stanke (Mozilla.cz) [:MikkCZ] from comment #3) > So is there any use of localizing the handlers? Uhm, I don't really know the answer (also note that Delphine owns mobile localization these days). @Sebastian Do you know if we use feed handlers defined in region.properties in Firefox for Android? I'm starting to doubt that they were copied from desktop and stopped working at some point, maybe when we switched to native Android.
No, to my knowledge we do not use any localization data for that. For external apps we use Android's Intent system  which will offer various installed apps that can handle a specific Intent (or open in the default app if the user selected one).  https://developer.android.com/reference/android/content/Intent.html  https://developer.android.com/guide/components/intents-filters.html
Thank you Sebastian and Francesco. Let's close this then as invalid, if there is no point in the protocol handlers strings for Fennec.
