Yes, it should. But this is also why you use uBlock Origin to block tracker scripts.

Firefox is my daily on desktop, but on mobile it's Safari. I finally got around to installing uBlock Origin Lite on iOS. I used to run the Firefox version on iOS, but that was discontinued long ago, and I never replaced it. I feel like a bit of an idiot for not doing this sooner.

Don’t beat yourself up, uBlock Origin on iOS is only four months old.

There are other ways to track. Containers offer a bit mote protection, but the IP address is still visible (unless VPN).

Containers don’t offer a benefit over normal browsing for this, Firefox already blocks and isolates third party cookies.

Caching is also a tracking signal.

Caches are also isolated. One of the reasons you shouldn't use a JavaScript CDN any more.

I assume you mean a public CDN, like code.jquery.com. There’s still reasons to serve JavaScript from your own CDN, like code splitting and serving the bundles closer to the user.
