Firefox 7.0.1 has stopped working on my wiki (hull.ac.uk/awe). So has Hotmail: both still do in IE 7.0.5730.11. The connections seem fine: it's just the html no longer displays. Have I deleted some code/action unwittingly?

I use Firefox 7.0.1 on an old Dell machine with Windows XP Home edition. For years, I have used Firefox to work on my wiki (hull.ac.uk/awe) with no trouble. In the last month or so, the browser has refused to implement the wiki mark-up in the way I am used to seeing it, whereas Internet Explorer (7.0.5730.11) still does. Hotmail also no longer works in firefox, tho' it's fine in IE. (In one paranoid moment, I feared that Microsoft was blocking Mozille; but this seems most unlikely.) The connections seem fine: it's just that the browser no longer implements/displays the marked-up text in the way I want (and am accustomed) to see it. Have I deleted some code/action unwittingly? If so, how can I get it back?

Try to update to Firefox 8.0.1

Thanks. Despite deep technological ignorance, I struggled through to do what you suggested. My Firefox now works as it did.
