Yeah, well firefox downloads latest.php when it automatically refreshes (occasionally) and it is annoying, why is this...

You'll find that it happens with other PHP pages as well (and also I find PDF's are more common and so are some others).

It happens when the page fails to load. Do you have a slow Internet connection?

No, 8MB line.

I do download torrents though, and I think it usually happens then.

You probably have up to 8MB, not 8MB. It's likely that you get around 4-5MB, with torrents going full speed then it is going to cause some browsing problems if you have no bandwidth left =p

yeah ,
my internet sucks when I am downloading a torrent, it takes like 10-20 seconds

Do you use your wireless connection when this happens? If your at a distance than the Internet will be much slower .

Well I'm about 10-20 metres away, but our house has quite thick walls

Firefox probably messes up with the headers because of your connection problems when downloading torrents, so it'll try to download the file.

You guys mean 8Mb right?
