I have a problem with connecting Steem using SteemJs https://github.com/adcpm/steem
Problem appears only on firefox browser, but Chrome Works correctly.
Our app is coded in Yii2 and JavaScript, which works fully in front-end
<script src="//cdn.steemjs.com/lib/latest/steem.min.js"></script>
<script>
          steem.broadcast.comment('5K8eZVEAMkfejyHxeQJ9R4wvrXowwz7kcxcTVwFGpeGq1x2iKRb', 
             '', 
             ‘test', 
             'sci', 
             'this-is-a-test-article-2', 
             'this is a test article2', 
             'test', 
             '', 
            function(err, result) {
                console.log(err, result);
        });
Problem in the following process: When running request to blockchain , it return null in Chrome. Null is mean ok! so everything is fine
But when running on Firefox error occures:
Error: 3030000 tx_missing_posting_auth: missing required posting authority
Missing Posting Authority sci
…..
 {"ops":[["comment",    {"parent_author":"","parent_permlink":"test","author":"sci","permlink":"this-is-a-test-article-2","title":"this is a test article2","body":"test","json_metadata":"\"\""}]],"sigs":    ["STM7x7kJhdKzu7gie8gPg5uUDNmLjbcXx7ek2H8UtKxH8qub3V2ut"]}
th_a  transaction.cpp:172 verify_authority
Sigs here - is always different,but should be same and must be equal to public key from private: GLS8MfcHZyYioPBsmoYp8AZf4mbwZdsarunFRvuWUySqb3nwPeRwb.
In chrome it is working right key.
This is browser-compatibility problem, or browser feature problem Please help identify a problem, and possible we can patch it or overcome in another way.
