Description

Having Tracker & Ads blocking enabled (both standard and aggressive modes) will break Reddit in numerous ways:
When not logged in, clicking into a post will pop-up a message saying Something went wrong.
When logged in, comments and sidebar fail to load and a Something went wrong message appears.

Steps to Reproduce

1. Make sure that Trackers & Ad blocking is enabled for reddit.com.
2. Clear cookies for Reddit.
3. Go to reddit.com and click into a post.
4. Notice the Something went wrong message that pops up on the bottom of the screen.
5. Login with your Reddit account.
6. Notice that your subscribed subreddits fail to load in the Reddit sidebar
7. Go to the comments section of any post with 1 or more comments.
8. Notice that the comments do not load.

Actual result:

When not logged in:

When logged in:

Expected result:

When not logged in, Something went wrong should not appear.
When logged in, subscribed subreddits and post comments should load. Something went wrong should not appear.
