Describe the issue

Recently, zhihu.com adds a mandentory login popup for every page. So nobody can read any user-generated-content on that site anonymously.

Hi, this cosmetic filter will also block the comment pop-up when clicking on "查看回复".

@lijunkang12 How about ##.Modal-enter-done then ?

[lijunkang12]

@uBlock-user The problem is that the comment pop-up and the login pop-up have the same class Modal-wrapper undefined Modal-enter-done.

[uBlock-user]

Seems to be working, did you try the filter above ? When I click on the pencil symbol button the popup appears.

Be sure to add zhihu.com#@#.Modal-wrapper when testing.

@uBlock-user imo those filters should be moved to annoyances list

[uBlock-user]

because they added X button now ?

[lijunkang12]

@uBlock-user No, with ##.Modal-enter-done, the comment pop-up is also blocked. As I have explained, the problem is that the login pop-up that we would like to block has the same dom class as the comment pop-up. I am looking for a workaround.

[uBlock-user]

@lijunkang12 We can remove it altogether if the regional list maintainers would like to fix this themselves.

[lijunkang12]

Yeah, I totally agree that this should rather be included in the regional list!

@lijunkang12

Since it's been removed, is it in the regional list already? I don't think they'll add it into the regional list because it's not an "ad" but an annoying popup.

[lijunkang12]

@proletarius101 I am afraid no.

By the way, I have found out that a cosmetic filter cannot work properly against such pop-up.

First, one needs #?#div.Modal-wrapper:-abp-has(>div.signFlowModal) rather than ##.Modal-wrapper as cosmetic filter. This one blocks only the login pop-up but not comment pop-ups.

However, if you try this one, you will find out that the rest of the page is gone even when the login pop-up is properly blocked, which means you can only view the content in the beginning of a thread. This is because zhihu.com loads a javascript that changes the webpage when the user has not logged in. So the only solution to avoid this mandatory login is to block this specific js file using the rule:
||static.zhihu.com/heifetz/main.signflow.f8d09c909f9b8108d429.js$script,domain=www.zhihu.com

It turns out to work fine. I do not know any side effect for the moment. On the other hand, as you said, this is not an ad but rather an annoyance, the regional list might not accept it. Maybe you could communicate with them on this subject?

[uBlock-user]

||static.zhihu.com/heifetz/main.signflow.f8d09c909f9b8108d429.js$script,domain=www.zhihu.com

Sure we can add that if you can confirm there's no breakage after adding that.

[lijunkang12]

Yes, I can confirm there is no breakage.

[proletarius101]

It should really be ||static.zhihu.com/heifetz/main.signflow.*.js$script,domain=www.zhihu.com as I proposed in the first place. They use generator like React so using a specific hash will not work for a long time. And I can confirm no breakage as well.

[lijunkang12]

Yes you are completely right. Sorry I didn't notice your proposition in the beginning! Let us use ||static.zhihu.com/heifetz/main.signflow.*.js$script,domain=www.zhihu.com then.
