Firefox displaying header info and weird characters instead of html - refresh ok

On the rare occassion Firefox (3.0.1) is incorrectly rendering my website. Instead of showing the web page, it displays the header info and random weird characters. I have attached an example screenshot.

When I refresh the page it displays ok.

I have been unable to replicate this problem on any other browser and it doesn't happen all the time of Firefox. Very random, sometimes it will be dozens on page views before I see the problem again, sometimes it will happen again within a couple of page views.

Any ideas? Does anyone know if this is a Firefox bug or is it something on my website/server?

 

I would try reinstalling FireFox3, as you should be able to view the website fine.

After that, clear everything, cookies, history, etc.

 

Thanks for the suggestion Blockis - unfortunately it didn't help :-(

I have done a clean reinstall of FF, cleared my cache & personal data, run FF in safe mode and the problem still occurs. It doesn't happen all the time, it happens randomly.

Any other ideas?

 

This is your server code being sent. You need to look at the headers to see what your server is sending and why. This is not a Firefox issue.

 

i agree to drhowarddrfine, i think your server or your coding is the problem...

 

try it in IE, if it still displays the error it must be your server/coding like mentioned above.

 

Well yea it happened to me and i reinstalled FF3 and it was fine!
