Cosmetic filtering and script injection both work fine, they’re just off by default. Everybody works around rule count limits by making the one app register itself as like six different “Safari extensions”, it’s just clutter not a limitation. It requires no permissions up front and later permissions only granularly and rarely, for me only on YouTube, while the Firefox version does require unrestricted access to all domains. I have never seen a “dynamic filtering capability” it lacks or an ad it can’t block, do you have any examples?

> it's got all the limitations of Manifest V3 which prevents it from doing a good bit of blocking

The only mainstream browser left that can still run the full version of uBlock Origin is Firefox.

All the others have the same limitations imposed by Manifest V3.

Regarding the cosmetic filtering and scriptlet injection, are these even relevant? Most uBO users already give full access to the extension, so they'll probably do the same to uBOL to (most permissions + complete filtering mode). So basically they will have these features anyway.

What I like about uBO Lite in Safari is that I can use it without allowing it access to any of my data (it works in a purely declarative mode if you want). Even if it’s unlikely that uBO would be sold to a sketchy company, at least this provides protection against any supply chain attacks.
