I request that the trunk builds allow the user to disable the fix for bug 154930, as was done in the 1.0 branch. The fix for bug 154930 is causing major problems with Yahoo mail (see bug 160339). According to the bugzilla comments regarding bug 154930, the current fix has caused signficant problems with various major sites. The problems were severe enough that the original fix was backed out of the 1.0 branch and changed to a user-selectable preference.
The decision to make the fix mandatory in the trunk was based on the belief that Microsoft would soon release an identical fix, forcing web sites to be compatible with the fix. A month has passed since then, and no fix has been forthcoming from Microsoft. According to the bug's discoverer, Microsoft has announced that it has no plans to issue a fix (see http://www.xwt.org/sop.txt). Given the current state of affairs, I suggest that the user preference from the 1.0 branch be migrated to the trunk, until such time as the major sites can be convinced to fix their sites.
