Well, I'm not sure exactly. It's really strange. I reverted back to 0.8.2 and the site seemed to load quicker. I use NoScript and Ghostery to prevent third party tracking, but I didn't see either of those two blocking anything until I upgraded to 0.8.3 (they won't block any third party scripts if they don't see them). I switched back to 0.8.2 and neither of those two (NoScript or Ghostery) reported anything. So I just assumed there was something different in the plugin versions.
I started troubleshooting, with the modes. I had it set to Normal, so I decided to try using Forced with 0.8.3. At first it seemed to work. Then it acted like it didn't again, as the browser (either Chrome or Firefox) would just sit there and load for awhile and NoScript/Ghostery reported seeing them again. Really strange.
Also, I'm mainly using this because a client wanted to use the Lockerz/AddToAny plugin and I wanted to block Lockerz. Your plugin seemed to work and made the site load quicker.
I have lockerz.com whitelisted in CSP for some reason, as the plugin may not function correctly if I don't. Not sure about that though, it's been a long time since I set up CSP for this site. So I guess I'm going to try removing that and experiment with a few other things.
Thanks for replying so quickly. I'm just going to mark this as resolved, since I'm not sure what's causing the issue.
