This can most easily be described by example. Go to the site: http://vancouver-webpages.com/META/ and follow the steps to reproduce. Reproducible: Always Steps to Reproduce: 1. Go to site http://vancouver-webpages.com/META/ 2. Middle click in the top right frame somewhere. 3. While autoscrolling, move the mouse into the lower frame. 4. Without leaving autoscroll mode, move the mouse around in the lower frame. Actual Results: Scrolling up and down while moving the mouse around in the lower frame. Expected Results: Scrolling down only. This bug is VERY similar to bug #223542. I believe that this bug explains the behaviour described in #223542 and that fixing this bug would also eliminate bug #223542.

Are you sure this isn't in your mouse settings? Middle buttons vary from mouse to mouse. The scroll direction is controlled but the pointer location relevent the the center of the page.

(In reply to comment #1) > Are you sure this isn't in your mouse settings? Not sure what you mean by your third sentence. However I do know that autoscroll is a feature of Firefox, not a feature of my mouse driver.

If they're the same thing, then duplicate makes more sense than blocks. *** This bug has been marked as a duplicate of 223542 ***
