Weird issue on ASUS forums

[mooms06]

Hi,

I've discovered a strange issue:

If the extension is enabled, it adds a footer* on each messages posted on ASUS forums, see the first and third post here.

*Like this: title="Google Translator Anywhere" class="itanywhere-activator bounceIn" style="left: 184px; top: 4px; display: block;">

Using Firefox 55.0.3 x64 on Win 7 x64.

Can be reproduced each time I post a message there with the extension enabled. Text is not visible when posting or editing the message.
