[Solved] How to integrate XMarks?

I've checked XMarks' site and Opera's extension browser but XMarks is nowhere to be found.

Is there a workaround or other way to integrate XMarks?

Here's my details:
-Platform: Win 7 32bit
-Browser Ver: 27.0.1689.69

I would really appreciate any help. Thanks~

Yey~ It did! Thanks @gwen-dragon
