Are there mouse gestures for safari?

Xgestures or if you have a multi-touch trackpad/mouse, you can swipe with two fingers to the left to go back or to the right to go forward.

Also have a look at BetterTouchTool.

 

Do you mean Xgestures or BTT?

You can also take a look at Magic Prefs, but I don't know of any professional company delving into gestures. Xgestures is a paid product though and I used it for quite some time, but BTT is quite good too, even if I don't have to pay for it.

And what do you mean by "polished"? BTT is still alpha and beta and for what it is, it offers a load of features that work quite good.

 

Have you tried BTT then? I run it on my Unibody Mac and it works without hiccups, and when there is one, a simple restart of the software solves it (once or twice since last November (2009)).

 

I should have clarified: BTT is programmed for the Magic Mouse and the Multi-Touch Trackpads Apple employs since 2008.
It is not meant for normal mice or trackpads.

Have you taken a look at XGestures? It is paid and easy to setup via System Preferences and allowed me to use mouse gestures in Safari as I was able to in Opera.
