Tree Style Tabs in Firefox

I’ve started using tree style tabs in firefox, I find it’s a much more natural way of organising tabs than a horizontal bar of text. Any tabs opened from a tab will automatically become a new leaf in the tree and operations on nodes can cascade down the tree.

This plugin does not deactivate the standard tab bar though, this conversation goes into further detail about it. But for now the answer is to add custom css to ~/.mozilla/.firefox/$profile/chrome/userChrome.css

#TabsToolbar {
    visibility: collapse !important;


I’ll add this to my dotfiles soon enough.

I also tried another plugin but found it a bit bloated.

It would be nice to have a plugin that could organize tabs with tags.
