Here's a real workaround for Gmail:
1. Install the Stylish Add-on (https://addons.mozilla.org/en-US/firefox/addon/2108) 2. Right click the icon --> Write style --> For google.com 3. Add "*{border-style: none !important;}"
Doesn't seem to fix other sites, though, so maybe there is more than one bug here.
