Waterfox 6.7.3 lets vertical tabs auto-hide at the edge

Waterfox 6.7.3 adds an option to auto-hide the vertical-tabs sidebar until the pointer reaches the edge of the window.

It also lets users stop audio indicators from widening tabs, and restores loading for older extensions including Roomy Bookmarks Toolbar redux and Tab Mix Plus.

The release fixes vertical-tab highlighting, narrow-sidebar close buttons and several appearance controls, while improving JPEG XL compatibility and restoring the standard new-tab layout without recommended stories or sponsored content.
