I use the Tree Style Tabs extension [0], which took some getting used to but is miles better for tab navigation. Vertical tab sidebar means you can see more tabs at a time, the collapsible tree means you can organize them into logical groups, and it's super customizable. Tab contrast and audio icons are identical to the way they were in FF 88.0 for me. [0] https://addons.mozilla.org/firefox/addon/tree-style-tab/ https://addons.mozilla.org/firefox/addon/tree-style-tab/
