Steps to reproduce:

  1. Open a url (I noticed this on imdb)
  2. Make a rule to hide any element
  3. Refresh the page -- sometimes, the element will be hidden, sometimes it will not.

I don't have any more information to share. I once even noticed it on DDG search results page.

Expected behavior:
uBO should work every time.

Orion and macOS:
macOS 12.1
0.99.109.1
uBO 1.39.2

    Very annoying issue. Spent ages tinkering with the filter lists thinking that was the culprit, only to realise that a page refresh changes what gets blocked

      Steps to reproduce:
      Go to Twitter.com
      Browse through your timeline or through a tag

      Expected behavior:
      Promoted twitter ads should not be appearing similar to uBlock origin on other browsers

      Orion, OS version; hardware type:
      MacOs Monterey 12.1
      Orion Version 0.99.109.1-beta (WebKit 613.1.12)
      Intel 2019 MBA

      Interesting - I've been using Twitter w/ uBlock origin on Orion for more than a month and have never seen an ad.

        Cannot reproduce - maybe select more lists in ublock?

        Also make sure that you are not using the compatibility mode - Twitter was broken on Orion before so you may have left it on.

          Not able to reproduce.

            eirk changed the title to uBlock Origin doesn't work, sometimes .

              joystmp I think it is a duplicate indeed, it's also about element/visual filters in uBlock Origin not working.

              Same issue can be seen often on (old) Reddit, where promoted articles will very often be visible, but sometimes it works and they're hidden, even on the exact same URL it's possible to see it suddenly work/break on refresh.

                Merged 6 posts from uBlock Origin is not blocking twitter ads.

                  Still present in latest beta with improvements for various extensions.
                  Initially it worked when I installed the new beta, but it always has worked intermittently. And soon enough it stopped working again.

                  Here's a screenshot where reddit promoted posts and cookie banner should be filtered but aren't on the latest beta:

                  The discussion gets hard to follow.

                  What is the Ask here and what are steps to reproduce?

                    I can reproduce this reliably:

                    1. Add a custom blocking rule twitter.com##a[href="/vladquant"]
                    2. Click the link below:

                    Expected: The post avatar and other links to the profile should be hidden
                    Actual: The avatar is still visible

                    Sorry for the weird example, but I had to use embedded media to force the page to open a new tab. A regular link reuses the same tab on this forum software.

                    Refreshing the Twitter page fixes the issue for me. I've also seen this when opening a new tab and pasting the address. But it doesn't happen reliably.

                      I found that if the content blockers is turned off, uBlock Origin would not work properly.

                        For me it's not reliable with or without the built-in content blocker enabled. I don't think it matters.

                          <Include steps to reproduce the bug; Did you try using Compatibility mode? If applicable, does Safari behave in the same way?>

                          1. Open a webpage
                          2. Ads get blocked by uBlock origin
                          3. But certain cosmetic filters or blank areas where the ads used to be are not properly removed
                          4. Refresh the page to see how it's supposed to actually look.

                          Expected behavior:
                          <What you expected to happen?>
                          Not needing to refresh the page every time I visit a webpage for uBlock to work properly.

                            Partially fixed with the Version 0.99.115.2-beta (WebKit 614.1.12) update, some pages are still janky like when you open a page in a new window or tab. Besides that, there's still a noticeable delay for when the cosmetic filter is properly applied and you can briefly see the placeholder area before it gets blocked.
