I installed adobe reader for pdf's and then it became my default so all of my pdf's were opening with adobe in the net etc. I then got annoyed with it so i made preview my default again and deleted adobe using the app cleaner app. now pdf's wont open in my browser (safari) but i can still sometimes save them and open them with preview. i've tried going through settings and system prefs and such and couldnt find anything ...this is really annoying me so if anyone can help that would be awesome.
