Using Firefox 44.0 example site: news.cnn.com problem : With uBlock Origin blocking the site, the comments are disabled. After hours wasted on this problem I found out the following : 1. The commenting platform is Livefyre. 2. There are **many** elements from Livefyre to this site, and the 'common user' would not be able to figure out which ones were necessary to allow in order to be able to read/post comments on a site. 4. For some reason, some filter list writers/maintainers/whatever consider the comment section to be a nuisance on (at least some) sites - I have found that it is hit and miss whether comments will show or not show on a site without turning off add blocking on the site. 5. The wiki for your project is very thin on instructions for creating exception filters, actually the only way I found out how to do an exception filter was to go to the AdBlock Plus page you linked to for their compatible filter syntax or whatever. The 'average user' isn't going to want to run to the Adblock Plus forums every time they go to a site and can't see the comments section (or something else they want to see on a site that a filter list writer has arbitrarily determined needs to be blocked) and ask someone there to help them create an exception filter. I would suspect, and correct me if I am wrong here, that if the people who answer questions in the Ablock Plus forums know you are using uBlock for your ad blocking instead of their extension, they might get tired of answering those questions fairly quickly as well. uBlock Origin has no user support forum to ask these questions in though, posting here in issues was the only solution I could think of. What elements need to be unblocked in order to make something like the comments section work? xhr? Script? In-line script? Images? Frames? CSS? Some of them or all of them? If only some, which ones? I used the element picker to select everything for the frame for the comments section. I created a rule, the only rule it seems to allow creation of is blocking rules, not exception rules. I modified this rule with @@ to make it an exception rule. Didn't work. Then, I went in and messed around with dynamic blocking, clicking all of the elements (quite a long list) to green, which if I understand your documentation means allowed. Didn't work. There needs to be an easy method incorporated into the extension so that a 'common user' with no programming or web page editing skills/knowledge can make an exception so that they can show something they want to see, whether a list writer/maintainer thinks it is an annoyance or not. I don't know enough about programming or server side programming (whatever you would call it) to know what this would be. Maybe a way to use the Element Picker to select an area and make an exception rule to allow it? Maybe an easy way to look up what lists have that particular function blocked, and then easily write an exception rule that overrides the blocking rule? I don't know. Even though I am sure the author/programmer of this extension is a busy person, maybe he could get some help from knowledgeable people here to write more extensive documentation? Maybe open up a support forum somewhere like Adblock Plus has, and the knowledgeable people here take the time to scan the forums from time to time? I really do like your extension, and I know there are thousands of others out there who do too. But this is a very frustrating problem, and one might want to be able to discover how to handle some of these things themselves instead of having to go to the Adblock Plus forum to ask for help. Anyway, I hope that this post will be taken as constructive, it isn't meant to denigrate your extension, which as I said I think is excellent. And I would appreciate you taking a look into this issue. Thank you
