Aaaargh! (Sunday night 1148 GMT)
Many thanks to Tim Chesterton for pointing out that Firefox seems not to be loading the front page correctly just now. Safari is, and access to individual posts through the Diocesan webpage (www.oxford.anglican.org) is OK. I've reported to Blogger help, and hope this is resolved very soon indeed...
Aha! Update! (Monday morning 0824 GMT)
Have fiddled with the number of posts displaying on a page in the dashboard, adjusted to 12, and hey presto! Seems to be OK. If you are still experiencing problems with Firefox and the front page here, please comment on this post... Unless you are experiencing problems that mean you can’t view this post — Infinite nested loop alert!
