Chuppito, I already explained that in this topic, but you are refering to the Post Subject, not the topic title.
See one of my earlier replies in this topic to clearly see the difference.
If you want to put it infront of the Post subject, it's a bit more difficult, you can use
viewtopic_body_post_subject_before as mentioned, but that is not inside, so outside, the post subject's
h3 element, which is a block element. So you might be able to do some CSS magic and make it float infront or what ever.
And you do not have to disable the extension, if you purge the cache and force refresh the page (Ctrl + F5), that usually works for me.
