Generally it works well, but what's particularly annoying is that it hides cookie walls, resulting in non-functional websites until I disable content blockers, close the dialog and re-enable them. Not sure if uBlock does any better, though.

Ghostery does the same, but has more fine-grained per-website controls. You can for example turn off just the consent-popup-blocker function for a website while keeping the anti-tracking ad-blocking functions.

Use a bookmarklet to sweep sticky elements for those situation. Not ideal, but works fine.

Use Safari’s own built-in “Hide Distracting Items”. It’s also pretty good at hiding the few remaining “disable your ad blocker to continue” popups Wipr doesn’t yet catch.

This is my only complaint. Most of the websites work fine, but others get stuck. I don’t know if Wipr 2 solved the issue.

We occasionally have this with the actual full uBlock Origin on Firefox as well.

I don't think there's a general solution for this issue. Content blockers need to provide a workaround for each situation, if at all possible.

At least it's possible to contribute to uBlock Origin's filters.

Origin feels much faster to me than Wipr
