Safari 5 tabs on Safari 6+. Cosy.

Tested on Safari 6, 7, 8, 9.

Safari 9 was tested under El Capitan and Yosemite.

If you're using an old version of Safari/OS X and you're having problems with the latest version, try the older ones.



How to Install

El Capitan (OS X 10.11)

EasySIMBL does not work anymore because of the System Integrity Protection introduced in El Capitan.

It has been confirmed that the old SIMBL-0.9.9 works, but only after disabling SIP.

Here's the guide for installing SIMBL on El Capitan:

After that, download cosyTabs, extract it, and place cosyTabs.bundle in /Library/Application Support/SIMBL/Plugins/

For advanced users

Obviously, there is no need to disable SIP (and reboot 4+ times). If you can extract SIMBL from the .pkg, boot into Recovery or any other OS, then you can simply copy the SIMBL's files to the correct paths.

OS X 10.10.4+ (Updated Yosemite)

  1. Download and install SIMBL-0.9.9
  2. Download cosyTabs here: Releases
  3. Extract it, and place cosyTabs.bundle in /Library/Application Support/SIMBL/Plugins/

OS X 10.7 → 10.10.3

  1. Download and install EasySIMBL
  2. Download cosyTabs here: Releases
  3. Extract & Install cosyTabs:
    • Open EasySIMBL and drag & drop cosyTabs.bundle into the list.

Note about Safari Technology Preview

I could not get SIMBL to inject into Safari Technology Preview (STP), so STP is unsupported at the moment.

Please create an issue if you have a clue on how to fix this error:
