When you open a new tab, (like with cmd-click) new tabs appear immediately to the left of the existing tab. So, if you open up three links as new tabs from the first page, the order will be:
FIRST, 3, 2, 1.
This is normal behavior for Safari. Chrome opens them at the far end, so: FIRST, 1, 2, 3.
In Safari, you can enable a "secret" debug menu.
- Open Terminal
- Put in: defaults write com.apple.Safari IncludeInternalDebugMenu 1
(or '0' to turn it off).
In that debug menu in Safari, towards the bottom, there is an option "Tab Ordering".
Under that:
- Position of New Tabs <--
- Apply Position to Spawned Tabs
- Apply Position to All Bank Tabs
- Suppress Relating New Blank Tabs to Selected Tab
- Show Tab Ancestry in Tab Title
In that first menu option (Position of New Tabs) you can choose:
- After Current Tab <-- (This is the default)
- After Related Tabs
- After Last Related Tab
- After Last Tab
This would be be fantastic to have available in Orion as well.
