Firefox also has some interesting add-ons that are useful for certain tasks, and I've also started using Chrome on an experimental basis.
The main attraction of Camino is that it works with the Joomla CMS that iTWire uses (there's a nagging incompatibility with Safari when editing articles), and its Mac-native user interface seems more comfortable than Firefox.
Camino also does a better out-of-the-box job of blocking unwanted content than Firefox, if that's important to you.
Since Camino uses Gecko as its HTML engine, any security updates for Firefox usually signal the imminent arrival of a new version of Camino. Yes, that does mean disclosed vulnerabilities are potentially exploitable in Camino for a few days, but you can't have everything.
It contains the security and stability fixes in Gecko 126.96.36.199, fixes a couple of relatively regressions, and improves Flash and ad blocking.
