STR in Fx: - move mouse pointer on search provider icon in the search widget field - hold ctrl + use mousewheel in downwards/upwards direction exp.: you can browse through the given list of providers without opening the popup (just as ctrl+k + ctrl up/down-arrow works) actual: nothing happens works: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9.1a2pre) Gecko/20080812045727 Minefield/3.1a2pre fails: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9.1a2pre) Gecko/20080813032636 Minefield/3.1a2pre => http://hg.mozilla.org/mozilla-central/index.cgi/pushloghtml?startdate=2008-08-12+05%3A00%3A00&enddate=2008-08-13+03%3A00%3A00 (hope i got this correct) i presume this is a regression of fixing bug 378028 (http://hg.mozilla.org/mozilla-central/index.cgi/rev/a02e6af74ab8), but that's not more than a guess. therefore i filled this under general component. maybe roc can have comment on this :)
