Browser settings

To match icon colors to your theme, enable the experimental feature as follows:

• Visit about:config.
• Search for svg.context-properties.content.enabled and set the value to true.

This can also improve dark theme (Issue #154).

Tab groups

• To group tabs:
  • Select tabs by Shift + click or Ctrl¹ + click.
  • Drag one of the selected tabs and Shift + drop it on the tab you want to group.
  • Or from the context menu (right click on one of the selected tabs), select "Tab Group" -> "Group Selected Tabs".
• To add group label:
  • From the context menu, select "Tab Group" -> "Show Group Label" and edit.
• To collapse / expand tab group:
  • Click on the colored part will toggle collapsed / expanded state.
  • Or from the context menu, select "Tab Group" -> "Collapse (Expand) Tab Group".
• To cancel tab group:
  • From the context menu, select "Tab Group" -> "Ungroup tabs".

Tab groups will not be saved during private browsing.

Known Issues

• The extension can't hide the browser native tab bars because there is no API for that in WebExtensions. But you can hide them manually. Issue #5
• The context menu item of the original tab "Send tab to device" is not implemented because there is no API for that in WebExtensions. Issue #7
