Tracking Protection blocks feeds from loading (Reddit feeds not loading...)

[nicolaasjan]

Add-on version
Add-on version: 2.2

Describe the bug
Try to add a feed from old.reddit.com gives error.

To Reproduce
Steps to reproduce the behavior:

1. Go to https://old.reddit.com/r/uBlockOrigin/.
2. Click on rss feed icon in the address bar.
3. Scroll down to '....' n/a
4. See error (screenshot below)

Expected behaviour
See the content of the feed and be able to successfully subscribe to it.
It should open https://old.reddit.com/r/uBlockOrigin/.rss.

Extra context
Any already existing feeds from old.reddit.com are not updating.
And yes, I have already tried disabling Tracking Protection in Firefox.
That does not make any difference.

Works fine on my side:

Do you see any console errors ? Also, do you have any other extensions ? Some of them could be conflicting.

I can reproduce this. The following is logged on console:

Error: "0: (https://old.reddit.com/r/uBlockOrigin/.rss)" subscribe.js:84:13

I have the Old Reddit Redirect add-on installed, but I just tried disabling it and it made no difference. I don't think any of my other add-ons would affect it.

I have the Old Reddit Redirect add-on installed as well.
In the console I see:

Error: "0:  (https://www.reddit.com/r/uBlockOrigin/.rss)"                                            subscribe.js:84:13
    main moz-extension://8053ea25-5d76-42b7-97f7-66cbf83bf865/pages/subscribe/subscribe.js:50
    <anonymous> moz-extension://8053ea25-5d76-42b7-97f7-66cbf83bf865/pages/subscribe/subscribe.js:7
    EventListener.handleEvent* moz-extension://8053ea25-5d76-42b7-97f7-66cbf83bf865/pages/subscribe/subscribe.js:6

I even tried in a clean profile with only Livemarks installed, but that does not make any difference.

I have pinpointed the cause of this.
Trying in an even cleaner new profile with the default preferences unchanged the Reddit feeds were loading fine!
Under 'Enhanced Tracking Protection' ---> 'Custom' ---> 'Tracking content' must be set to 'Only in Private Windows'...

I don't really like that (never use private windows), but OK.
I guess uBlock Origin and uMatrix take care of the rest.
