Created attachment 287216 [details] testcase I'm getting a horizontal scrollbar again in current trunk builds on Google News. See testcase, this seems to have regressed between 2007-10-19 and 2007-10-20: http://bonsai.mozilla.org/cvsquery.cgi?treeid=default&module=all&branch=HEAD&branchtype=match&dir=&file=&filetype=match&who=&whotype=match&sortby=Date&hours=2&date=explicit&mindate=2007-10-19+04&maxdate=2007-10-20+06&cvsroot=%2Fcvsroot I guess a regression from bug 393096.
For me on Mac, widths 73-77px show the bug. This had better block.
Fixed by checkin for bug 399531.
Verified fixed with the testcase, using: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9b2pre) Gecko/2007120405 Minefield/3.0b2pre
