My BBLog Addon Version is: 1.3
No information, no idea.
I go on chrome://extensions/, but when I click on the addon it wont pop up or anything
When you read the FAQ or just see the screenshot at the homepage, you will see what you need to do.
Goto Battlelog and a new Icon left-under the battlefield 3 logo is visible.
In extension manager isnt any useable stuff for bblog (except the extension management to remove and update)
Click on them, thats it.
