Status: RESOLVED DUPLICATE of bug 1223839

(Firefox :: Theme, defect)

Description

Attachment: AudioOverlay.png

User Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:45.0) Gecko/20100101 Firefox/45.0
Build ID: 20160208194709

Steps to reproduce:

Open a tab that can play audio and pin it. (Having another tab next to it will help you see the change but is not required.) Start playing audio in the tab.


Actual results:

The tab becomes 1 pixel wider and all tabs shift 1px to the right. The reverse happens when the audio is stopped. Screenshot taken using a fresh profile on Firefox 45.0b4 for Windows 7.


Expected results:

Try and maintain the same width.
