"New Answers" very slow with Mozilla 1.8b

Starting yesterday it's been taking a long time to get <b>New

Answers</b> on the Unified Forum view when I use Mozilla 1.8b (Firefox

works just fine). I've always used Mozilla here so I don't think it's

the browser. Just now it took 7 minutes to load the page and it was a

<b>New answers in the last 48 hours</b> page. When I backed up and

tried again it worked correctly (which is what happened yesterday)

except it thought my last visit was at 6 this morning - my visits

during the day didn't register.
