问题
I have an html5 appcache running on a website, it works fine in Safari, Opera and Chrome but it fails to work on Firefox.
I have the following in my code:
<!DOCTYPE HTML>
<html manifest="./manifest.appcache">
<head>
and the following manifest.appcache file:
CACHE MANIFEST

/anchoring

I am using the code from here: http://jonathanstark.com/blog/2009/09/27/debugging-html-5-offline-application-cache/ to debug the appcache and display the output on the site.
In firefox the output from the debug code shows it downloading all the files and calling swap cache. If I then disconnect from the internet and click on a link to another page which should have downloaded I get the Unable to Connect message in Firefox, while doing the same in Safari, Opera and Chrome it works fine.
Any help and suggestions would be appreciated.
Thanks Steve

Look if the Server sets no-cache/no-store headers for the generated files. Firefox will then ignore the manifest in contrary to the other browsers.
回答2:
I had a similar problem. The problem was that FireFox cache file more aggressively, so I had to add these headers:
For the manifest:
Pragma: no-cache
Cache-Control: no-cache
Expires: date
And for the files:
Last-Modified: date
Cache-Control: no-cache
Expires: date
Replace date by the RFC 1123 formated current date.

check if the no-cache/no-store headers are set

I had a similar problem.
- Make sure the manifest file is served as type "text/cache-manifest"
- Dont try it out in Private Browsing mode in Firefox/IE. It only works in regular browsing mode. But it works in both modes in Chrome
While offline, a simple change in the URL could be a problem
http://localhost:8080/appdoesn't work on Firefox/IEhttp://localhost:8080/app/works on Firefox/IE
Both of them work in Chrome
- Use these handy resource viewers to get more detailed perspective
about:cache- Firefoxchrome://appcache-internals/- Chrome
Please fill in if someone knows what is it for IE.

In Firefox Preferences -> Advanced -> Network, in the "The following websites have stored data for offline use:" list, do you see your website? If so, try clearing your website from the list and then reloading your website.

Earl's answer above worked for me in combination with turning FireBug off.

I face the same problem too; this header is fix for me.
Content-Type: text/cache-manifest
