(Whiteboard: [uaoverride] [country-all] [sitewait][serversniff]) 

yahoo.com serves a desktop site to B2G. Bug 819210 added an UA override for this domain. The override should be removed once the domain serves mobile content to B2G. This bug tracks the evangelism for the site to recognize the B2G UA and the removal of the override at that time.
Tanvi, any idea of somebody at Yahoo we could contact about this?
For reference, the Firefox OS UA is:

Mozilla/5.0 (Mobile; rv:18.0) Gecko/18.0 Firefox/18

and we want Yahoo to treat this UA string as though it came from a mobile device.

See https://developer.mozilla.org/en-US/docs/Browser_detection_using_the_user_agent for our general recommendations about how to do UA-based detection.
Hello. This issues has been raised with Yahoo Devs, and we have alerted the team
responsible for maintaining the mappings of ua strings to product.

cool to hear. Do you have any status update?
I have removed the UA override from my device, and Yahoo is still sending the desktop site after the geolocated redirection. I'm testing from Canada so I got http://ca.yahoo.com/

Note that it still doesn't change anything for Firefox OS, which still receives the Desktop version.

hi,

Now yahoo.com treats ffos phone as mobile phone,but we still can not open yahoo.com successfully.

Does it means that if we can not open some website after we modify ua,we must contact the website to fix the issue??
Hi lecky,

OK let's see.

With the UA override, I'm receiving the mobile site and it is working. I can navigate and access articles.

Let's remove the UA override.

I'm being redirected to the desktop version of Yahoo.com in Canada.
aka http://ca.yahoo.com/?p=us


For testing with your own device, domains which have a UA override, see the flag [uaoverride] in the bug whiteboard, you need to remove the UA override. You might want to use the script at 
https://github.com/karlcow/webcompat/blob/master/moz/mozua.sh
It is not very user friendly for testing, we are trying to find a solution for this.

So Yahoo still doesn't recognize Firefox OS as a mobile browser.
Flags: needinfo?(lecky.wanglei)
Lecky, when you say you can't open yahoo.com "successfully" - could you explain exactly what problems you see?
hi,hallvord,

The browser error message says:The connection was reset.

By the way,there is no problem with my ffos phone's internet accession,

Other android phone can use my ffos phone's wifi hotspot share to access www.yahoo.com successfully.

lecky, 

1. which version of Firefox OS do you use? 
2. which device?
3. From which country are you trying to access yahoo.com ?

Thanks

It would be interesting to know if another Firefox OS user experience the same issue. Let's try.

Could you help us and tell us what is happening when you are trying to access http://yahoo.com/ from China. Thanks.

hi,karl,

i have tried to visit yahoo.com through ua:"Mozilla/5.0 (Android; Mobile; rv:18.0) Gecko/18.0 Firefox/18.0"

then i can visit yahoo.com successfully.

By the way,the original ua of my device is "Mozilla/5.0 (Android; Mobile; rv:18.1) Gecko/18.1 Firefox/18.1"

So my issue: can not open yahoo.com  is because of ua string.

Maybe yahoo.com only recognize the V1.0 device?
I note that I have forgotten to ping Jack. See comment #13

Not the same user agent sniffing depending on the locale.  That will make things more complicated.
Hi Beatriz&& Wayne:
We think this issue is a blocking issue, because we found some website can not recogonize Gecko/18.1 ,if we replace it to 18.0, it's fixed.

Thus ,we think we need Mozilla to consult with the popular website, add the Gecko 18.1 into list.

We thinks other OEM would also have this issue.

Hi lecky,

What we want: base the identification on /mobi/ and NOT the version number. :)
William,

Can you test this out here on v1.1 and v1.1HD with yahoo.com from Taipei?
Flags: needinfo?(wchang) → needinfo?(whsu)
Hi, Wayne,

It is hard to test this behavior by using "www.yahoo.com" in Taiwan since browser is always redirected to tw.yahoo.com.

So, I used "sports.yahoo.com" to test it.
After browser visits the "sports.yahoo.com", browser is redirected to mobile version.
I tested "V1.3", "V1.2", "V1.1.0", and "V1.1.0hd". All results are the same.

But, if I test this behavior by using "tw.yahoo.com", browser is redirected to web version.

I think this is a legacy bug.
Marked it as "koi?"

flag koi? per comment 20.

Unless Yahoo is shipped on device, I wouldn't block a release on an evangelism issue like this for which the fix is largely out of our control.
Yahoo! is in the process of being dealt with. 
From initial testing it is obvious that it will be complicated to solve. There are many properties and differences depending on the locales. Firefox OS releases schedule is orthogonal to Yahoo! (and all other Web properties we have issues with :) )
(In reply to Lawrence Mandel [:lmandel] from comment #22)

btw We have not tested the Yahoo! properties such as the one of Google, but I think we could expect different behaviors depending on the domains.

Because of the comment of Hallvord on Bug 953047, I tested from Japan with Firefox OS.

1. Erase the cookies and data history
2. close all tabs
3. checked that UA override is off

So on Firefox 1.2 I was redirected to the Mobile site in Singapore from Japan.
Could someone confirm for other countries?

Spoofing Firefox for Android Nightly as Firefox OS (using Phony) in Canada (Toronto) I get the desktop site when navigating to yahoo.com.
Thanks lawrence!
So there are really strong differences from country to country. 

Just to confirm I was not crazy, I requested the final Location, it goes to Singapore. It seems the YahooTrafficServer has a big impact.

I might have the start of a contact at Yahoo!. :) So progress.
so here I get the mobile version redirected to singapore.

* Setting UA override off
* Restarting the device
* erasing cookies 
If I manually enter us.yahoo.com I get redirected to us.m.yahoo.com
So for me it seems to be working and I'm inclined to close this one, but I need a confirmation from someone living in North America.
OK adam confirmed. I'm closing it as solved. I'm adding it to the list of UA override to remove. That's a big win.
