Having enabled tracking protection in nightly, I'm getting a block on pages which surprise me. It's frustrating when clicking on the shield not be be able to get to details of what has been blocked. I'm stuck in a position that I can't make an informed decision about whether to override (and I'm generally pretty well informed about such things). Even an indication of the number of tracking companies which were blocked, or similar would help. If we leave users in this position, they're more likely to turn this off when prompted to by sites.

Monica, Philipp, is this on the roadmap yet, and if not, can we put it there? :-)

Hi David, The list of blocked resources is available in the web console under the security tab (https://developer.mozilla.org/en-US/docs/Tools/Web_Console). Blocked resources will trigger a message "The resource at <X> was blocked because tracking protection is enabled". The web console is obviously only useful to power users. I'd like to know more about how many tracking protection users actually want this information before doing any UX or engineering work to expose it in the shield doorhanger. Let's keep this bug open until that's more clear. Thanks, Monica

When looking at the number of users who want this, it is important to keep in mind that there will be a self selection bias since users have to opt into Polaris (through a rather non-intuitive mechanism). That being said, I think exploring how to give users more information and (more importantly) control is a logical next step. The main feelings that people have when it comes to tracking is powerlessness. If we can do something about this, we should. We need to figure out what exactly that implies for the product, but I agree that we should keep this bug open for the time being.

It sorta sounds like we eventually need an improved flow for disabling tracking protection on a site when it's broken. Ideally with a step to gather feedback on what site is broken and how -- so that we (or the list provider?) can improve the feature. But maybe while this is still a Nightly-only feature (i.e. being used by more advanced users), making it easier to just see what's being blocked would be useful.

FWIW, the original mockup had a reporting mechanism included, but we left it out because it was V1 https://bug1029193.bugzilla.mozilla.org/attachment.cgi?id=8459849

I agree and filed https://bugzilla.mozilla.org/show_bug.cgi?id=1103241 to make this feature more accessible to non-wizards.

Will this make it into 42? It would be nice to let users know which trackers are being blocked so they know the feature is doing something genuinely useful and not a gimmick triggered by harmless URLs.

Monica's comment 2 requires opening the Browser Console, but we already put a prominent icon in the location bar when blocking trackers. Seems like clicking on that icon, then clicking "More Information" should give some more information about what's being blocked, no?

Javaun tells me this work just didn't make it into 42, I'm looking forward to seeing it in future versions

I've run into the same problem -- after seeing the shield for the first time, I was surprised not to find an easy way to see what has being blocked. I am used to this kind of feedback from various adblockers, so I expected the same here. This is with Firefox 54.
