Only Firefox supports extensions that provide an alternative interface to the tab bar. Alternative interfaces such as vertical tabs or tree tabs are very useful if you have many tabs open in a single window. Examples of these extensions:

• Tab Center Reborn – https://addons.mozilla.org/fr/firefox/addon/tabcenter-reborn...

• Tree Style Tab – https://addons.mozilla.org/en-US/firefox/addon/tree-style-ta...

• Tree Tabs – https://addons.mozilla.org/en-US/firefox/addon/tree-tabs/
