Could you attach the HTML using the "Add an attachment" link? It makes things easier to deal with.

Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9a7pre) Gecko/2007071105 Minefield/3.0a7pre Testcase WORKSFORME on trunk. Paul, can you test with a trunk build  and confirm? I'd suggest using a new profile to test: http://kb.mozillazine.org/Profile_Manager.  http://ftp.mozilla.org/pub/mozilla.org/firefox/nightly/latest-trunk/
Tested it in Minefield: as Adam put it, works fine there. But the issue is in: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:220.127.116.11) Gecko/20070515 Firefox/18.104.22.168 I'm not familiar with the update/release scheme's of FF/Mozilla. If the issue is allready fixed for FF3.0, any change of getting that fix backported to the 2.0 branch? Paul
The general policy is that non-critical fixes (i.e. fixes that don't affect security or stability) don't get checked into stable branches.
Resolving as WORKSFORME. We should still get a testcase checked in for this, though.
"We should still get a testcase checked in for this" meaning? Should I do something, or?
