Revision 1630, run the whole test suite on Firefox 1.0. Easiest way is to grab Portable Firefox from here:
http://prdownloads.sourceforge.net/portablefirefox/Firefox_Portable_1.0.8_en-us.zip?download
The following tests fail:
TestLinkEvents
TestButtonEvents
TestSelectEvents
TestRadioEvents
TestCheckboxEvents
TestTextEvents
TestFireEvents
They all fail as the initial "focus" event all have the shift, ctrl, meta and alt keys held down inappropriately.
Just prior to this, in revision 1630, I'd implemented some fixes to support FF 1.0... apparently you can't just set those values directly in 1.0. To get this right, we'd probably need to add some explicit support to handle these events for FF 1.0.
