1099105 - maps.yandex.ru sends Firefox Mobile to an apps download page

Status: RESOLVED FIXED

(Web Compatibility :: Site Reports, defect, P1)

Description

[Konstantin A. Lepikhov]

Looks like their UA detection engine doesn't know anything about FxOS

The maps.yandex.ru site behaves very differently in different browsers.

In Firefox on Android it redirects to Android Marketplace.

If I spoof as Safari on the iPhone, I get to the maps website, nice and mobile-friendly. At first glance it seems to work perfectly well in Firefox too (although according to the hostname it's in "beta").

If, however, I send the Firefox OS User-Agent string, I'm taken through a pretty confusing chain of redirects:

Wow.

It would be cool if Firefox OS (and perhaps Firefox on Android too) could simply be sent to the beta.maps.yandex.ru site, like Safari.

We don't support FxOS anymore, but this reproduces on Firefox for Android still: we get an app download page, and Chrome Mobile gets a nice mobile site (after you decline an app download).

To investigate how we behave if we spoof as Chrome Mobile.

When entering https://maps.yandex.ru/

* Firefox Android 
  is redirected to https://mobile.yandex.ru/apps/android/
* Firefox Android with Chrome UA 
  is redirected to https://yandex.ru/maps/
  (working on Gecko)

Have we tried our Yandex discussion mailing list?

Done.

For people reading this bug, the user agent for Firefox Android  follows this pattern:
User-Agent: Mozilla/5.0 (Android 5.1.1; Mobile; rv:52.0) Gecko/52.0 Firefox/52.0

In General the User agent strings are documented at
https://developer.mozilla.org/en/docs/Gecko_user_agent_string_reference

Experiment this morning:

0. With Firefox Desktop
1. Activate responsive mode
2. Put DPR = 3, activate touch events
3. Set UA string to "Mozilla/5.0 (Linux; Android 4.4.4; SH-01G Build/SB080) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/46.0.2490.76 Mobile Safari/537.36"
4. Enter https://maps.yandex.ru/ we get redirected to https://yandex.ru/maps/


zoom in with +, zoom out with +, change layers, geolocation, traffic information. 
All of these are working in Gecko (when faking the UA to be chrome).

The "Download App" overlay can now be dismissed and the site can be accessed.

[Tested with:]
[Browser / Version: Firefox Nightly 64.0a1 (2018-09-13)
Operating System: Google Pixel (Android 9) - 1080 x 1920 pixels (~441 ppi pixel density), Samsung Galaxy S7 Edge (Android 8.0.0) - Resolution 1440 x 2560 pixels (~534 ppi pixel density)

Thus closing the issue as Fixed.
