I have the following code:
<a href='https://api.twilio.com/2010-04-01/Accounts/xxxx/Recordings/yyyy' target='newframe'><div style='text-align: center;'>Play</div></a>
<iframe name='newframe' frameborder='0'></iframe>
but when I click on the "Play" link, in FF it opens in a new tab instead of the frame. It is working fine in IE and Chrome.
It looks like it is the Tab Mix Plus addon because it works fine when Tab Mix Plus is disabled. I have tried every setting in Tab Mix Plus I can see that may change the behavior but no luck yet. The Tab Mix Plus settings are attached; Firefox version: 23.0.1; operating system: Win 7 SP1.
