[Feature] Always hide tab bar

[michaelhthomas]

Is your feature request related to a problem? Please describe.

When using a tabs sidebar plugin like Sidebery, the tabs shown at the top of the screen are redundant.

Describe the solution you'd like

An about:config setting that allows hiding the tab bar regardless of the number of tabs open.

Describe alternatives you've considered

Adding additional css to always hide the tab bar.

Additional context

That is not actually in the domain of this theme. Developer can't know which extension everyone has. To hide the horizontal tab bar use your own css (either in sidebery css or in your own userChrome.css): / hides the native tabs /

TabsToolbar {

visibility: collapse; }

@sekurilabs is right, you can add extra custom CSS when needed. I don't think that this is in the scope of the theme.
