Firefox Add-on: https://addons.mozilla.org/en-US/firefox/addon/tree-style-tab/
For getting rid of the horizontal tab bar to save vertical space and reduce confusion, edit userChrome.css
to add this:
/* Hide tab bar in FF Quantum */
@-moz-document url("chrome://browser/content/browser.xul") {
#TabsToolbar {
visibility: collapse !important;
margin-bottom: 21px !important;
}
#sidebar-box[sidebarcommand="treestyletab_piro_sakura_ne_jp-sidebar-action"] #sidebar-header {
visibility: collapse !important;
}
}
To find your userChrome.css
file:
- Go to
Help
->Troubleshooting Information
(this should openabout:support
in a new tab) - Find the entry "Profile folder" and copy the path or click on "Show"
- Open the
chrome
sub-folder or create it if missing - Open the file
userChrome.css
or create it if missing

- use
F1
to show/hide the tree-style sidebar- the shortcut can be configured in the extension's preferences, I've set mine to Cmd+Shift+O
- add
%
in front of queries in the address bar (Awesome Bar) to search your tabs, see help page
No longer works. Latest update removes window controls( close, minimize buttons) and the title bar is just blank.
