  • Change opening order – tabs will open to the right of the most recently opened. Please refer to the example below. Example of changing opening order[a][b][c] are the current opened tabs with [a] being the current tab.
    [1][2][3] are the new tabs opened in that order.
    [a][b][c][1][2][3] -> [a][3][2][1][b][c], this is how tabs open without Change opening order.
    [a][b][c][1][2][3] -> [a][1][2][3][b][c], this is how tabs open with Change opening order option checked. :::
• Open duplicated tabs next to original
• Move tab from ‘Switch to tab’ next to current one When using ‘Switch to tab’ from address bar popup, move the tab you switching to next to the currently selected tab.
  This only applied when the tab you switching to is in the same window.

Groups of bookmarks/history

When opening many tabs from bookmarks group or history loading time for all tabs can be long, especially when multi-process (aka E10s, Electrolysis) is enabled.
It is recommended to enable these options when opening many tabs.

• Load tabs progressively – load tabs no more than 3 tabs at a time.
• Don’t load tabs until selected – all background tabs remain unloaded until selected.

For both options you can set the amount of tabs that serve as a threshold to enable the option.
