Works, but half as much as claimed. Nothing whatsoever results from scrolling over the field - I refer to both the Search Bar and the Location Bar - but clicking the added icon does clear the field.
I tend to agree with the user who does not want any [tacked-on clear-by-scroll] feature you can't disable: very unwise change, considering the other functions of scrolling. I'd like to go back to v1.5.
Sorry, I didn't update the addon description, only the version notes. The mouse wheel functionality was removed, if you want this, look at https://addons.mozilla.org/de/firefox/addon/wheelclear/ which enables every field to be cleared with the mouse wheel.
