1696694 - Proton tab mute button is too large and is too easy to misclick, changes text height

Status: RESOLVED DUPLICATE of bug 1693066

(Firefox :: Theme, enhancement)

Description

[u658943]

User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:88.0) Gecko/20100101 Firefox/88.0

Steps to reproduce:

Enable proton tabs in nightly and start playing a video/audio in a tab

Actual results:

The button to mute/unmute tabs is too large, covers the entire tab, changes the text height in the rest of the tab, and generally feels out of place.
It is easy to misclick this when trying to select or drag a tab and mute your tab by mistake.

Expected results:

The tab mute button should not be so large.
Please revert the tab audio mute switch to how it was prior to proton, where it was just a small speaker button to the left of the 'X' button.

The Bugbug bot thinks this bug should belong to the 'Core::Audio/Video: Playback' component, and is moving the bug to that component. Please revert this change in case you think the bot is wrong.
