I used this as the URL originally, but maybe anchor links are removed?

I currently use Wipr on macOS and iOS. I’ll give this a spin, however, what are the biggest downsides of the MV3 variant over the original MV2?

The biggest are that not all filtering capabilities are supported in MV3 and that the filter lists are only updated when the extension itself is updated. More details in the uBOL FAQ:

There's extremely limited user customization. You can't tweak filters per site or easily add new filters by selecting elements on the page.

It's unclear if these are technical limitations of MV3.

I know Safari can be fast, but is it up to scratch in terms of security? I remember reading somewhere that it doesn’t even isolate tabs as separate processes.

That hasn't been true in like 10 years. You can check the process hierarchy yourself in Activity Monitor and see its many processes, including one for each loaded site. It also uses separate processes for sandbox access, image decoding, video decoding, Metal compilation, and audio, among others.

I thought the SLAP exploit specifically worked only in Safari due to deficient site isolation, though? https://open-web-advocacy.org/blog/slap-and-flop--apples-lac...

That's from February of 2025.

Is @gorhill bringing safari support back into the main branch? That’s cool.

Will it work on mobile/ios?

In the link it says "for Safari on both macOS and iOS", so I hope it should work in iOS as well.
