Ссылка на баг: Remove the browser.tabs.closeButtons pref.
Мотивация:
The browser.tabs.closeButtons pref is only discoverable via about:config. It provides other locations for the tab close buttons, but none that we plan to move towards in the future.
These would be better supported and more discoverable if they were implemented by an add-on.
0: Display a close button on the active tab only 1: Display close buttons on all tabs (Default) 2: Don’t display any close buttons 3: Display a single close button at the end of the tab strip (Firefox 1.x behavior)
Because we are removing this pref, we will effectively be migrating users back to the default value of 1.
В комментариях естественно срач.
И собственно вопрос – кому нужно напинать в мягкие места, чтобы настройку вернули?
