We fixed the below for desktop in bug 1243729 but the fork for Android at https://mxr.mozilla.org/mozilla-central/source/mobile/android/components/LoginManagerPrompter.js?rev=b6e38de09b1a#276 wasn't fixed. +++ This bug was initially created as a clone of Bug #1243729 +++ User Agent: Mozilla/5.0 (Windows NT 6.3; Win64; x64; rv:47.0) Gecko/20100101 Firefox/47.0 Build ID: 20160127030236 User Agent: Mozilla/5.0 (Windows NT 6.3; Win64; x64; rv:44.0) Gecko/20100101 Firefox/44.0 Build ID: 20160123151951 Prerequisites: Have at least 2 logins saved for Twitter in browser. Steps to Reproduce: 1. Login to Twitter with one of the saved accounts. 2. Go to Twitter->Settings->Password screen. 3. Enter the current password and the new one. 4. Click on "Save changes" button. 5. Select from `Confirm Password Change` window the username for which the password has been changed. 6. Click on "OK" button. 7. Open a new tab and go to about:preferences#security, click on "Saved Logins..." button. 8. Observe the username for which the password has been changed. Expected results: The username is displayed and only the password is updated. Actual results: The username is blank. This issue is reproducible also on Windows 10, Mac OS X 10.11. == Tim, can you make the same change as attachment 8740261 [details] [diff] [review] but for mobile?

Margaret, making sure you see this. We can still land a fix for this in fennec beta 13.

Kevin can you test this before we uplift once Tim lands a fix? We are a little bit rushed (hoping to land this on m-b tonight or early tomorrow morning)

Is this bug still repro on Fennec? I am seeing `this._updateLogin(selectedLogin, aNewLogin.password);` here; `_updateLogin()` does not take `aNewLogin` as a whole as the argument. https://mxr.mozilla.org/mozilla-central/source/mobile/android/components/LoginManagerPrompter.js?rev=b6e38de09b1a#306

Good point, I guess bug 1016051 didn't get fixed for Android so this bug isn't present. Sorry about that. We can file a separate bug to port bug 1016051 to Android.

Thanks for checking. We don't need to track this, then.
