As reported by several of you there were some issues with my extension in version 1.4
Your chrome extension is not working properly. I mean, when I logged in through my codechef account, I get only one tick for my last submitted and accepted answer in the past may long contest.
The problem is that structure of the page is slightly different when user account is or is not linked with facebook account.
I hope that this is fixed now in version 1.5.
Also several times there was problem to download the extension, so I converted the extension and now you can download it from Chrome Store:
And I ported it also to Firefox addon:

Hope it will work fine and help to all of you.
Thumbs up!!
