Env: Minefield (nightly build 20061217), WindowEyes 6.0 (not required though) Problem: When in edit mode, arrowing to a editable field within a DHTML spreadsheet you are not able to edit the field. Steps to recreate: 1. Start Firefox and WindowEyes (not needed to recreate problem), load the url: http://www.mozilla.org/access/dhtml/spreadsheet 2. Arrow to an editable field, press enter and try changing the field. 3. You will noticed that when pressing enter the field will change to a string "undefined". Note: This problem occurs with or without a screen reader running, also this is a regression since it work for me on Bon Echo.

This is definitely a regression in Minefield. We could either try to find the regression window or create a minimal testcase. Martijn, are you willing to help us narrow this one down?

I needed to do shift->reload for testing to get the regression range, reliably. This regressed between 2006-11-26 and 2006-11-27: 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=2006-11-26+04&maxdate=2006-11-27+05&cvsroot=%2Fcvsroot I think this is a regression from bug 309438 somehow, because with the 2006-11-26 build, I get application/xhtml+xml as the document type, while for builds after that, I get text/html as the document type.

Changing the network.http.accept.default pref from: text/html,application/xhtml+xml;q=0.9,application/xml;q=0.8,*/*;q=0.7 to: application/xhtml+xml, text/html;q=0.9,application/xml;q=0.8,*/*;q=0.7 fixes it for me.

Thanks Martijn!
