HTML 5 appcache works in safari / opera / chrome but not firefox

I have an html5 appcache running on a website, it works fine in Safari, Opera and Chrome, but it doesn't work in Firefox.

My code has the following:

<!DOCTYPE HTML> <html manifest="./manifest.appcache"> <head>

and the following manifest.appcache file:

 CACHE MANIFEST / /accessibility /anchoring /areas-of-application-in-business /calibrating-rep-system-preferences /circle-of-excellence /collapse-anchors /contrastive-analysis-and-mapping-across /convincers /creating-an-air-of-authority /decision-making /elicitation-of-submodalities /embedded-commands /embedded-commands-2 /eye-patterns /four-types-of-feedback /home /how-to-remember-names /introduction-to-anchoring /introduction-to-nlp /key-elements-of-the-meta-model /language-and-communication-model /language-patterns /leadership /modelling /my-action-plan /new-behaviour-generator /nlp-presuppositions /outcome-thinking /pacing-and-leading /perceptual-positions /predicate-phrases /predicates /preference-test /presupposition-cards /presuppositions /privacy /rapport /rapport-pacing-and-leading /representational-systems /sensory-acuity /strategies /structure-for-adjusting-feedback /structure-of-nlp-techniques /structure-vs-content /submodalities /submodalities-and-strategies /submodalities-checklist /terms-and-conditions /the-6-deadly-words /the-meta-mirror /the-power-of-presuppositions /the-problem-frame-and-the-outcome-frame /user-profile /well-formed-outcomes /what-is-nlp /userImages/nlp_language_comm.png /css/mobile.css /css/style.css # Hash: a4e8f4f6a4dd45dd3e8acdaae8546a0a

I use the code from here: http://jonathanstark.com/blog/2009/09/27/debugging-html-5-offline-application-cache/ to debug the application and display the output on the site.

In firefox, output from the debug code shows that it downloads all the files and causes the swap cache. If I disconnect from the Internet and follow the link to another page that needs to be loaded, I get the message “Unable to connect” in Firefox, doing the same in Safari, Opera and Chrome, this works great.

Any help and suggestions would be appreciated.

Thanks Steve

See if the Server sets the no-cache / no-store headers for the generated files. Firefox then ignores the manifest, unlike other browsers.

I had a similar problem. The problem was that the FireFox cache file is more aggressive, so I had to add these headers:

For 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 with the current date of RFC 1123.

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

I had a similar problem.

  • Make sure the manifest file is in the form "text / cache-manifest"
  • Do not try to use it in private browsing mode in Firefox / IE. It only works in normal viewing mode. But it works in both modes in Chrome

  • Offline, simply changing the url can be a problem

    • http://localhost:8080/app does not work in Firefox / IE
    • http://localhost:8080/app/ works in Firefox / IE

    Both of them work in Chrome.

  • Use these handy resource viewers to get a more detailed perspective.
    • about:cache - Firefox
    • chrome://appcache-internals/ - Chrome

Please fill in if someone knows what it is for IE.

In Firefox settings → Advanced → Network, in the list “The following websites store data for offline use:”, do you see your website? If so, try clearing your website from the list, and then reloading your website.

The answer from Earl above worked for me in combination with disabling FireBug.

In the settings of Firefox → Advanced → Network, in the section “The following websites store data for offline use:” list, do you see your Website? If so, try clearing your website from the list and then reloading your website.

I am also facing the same problem; This heading has been fixed for me.

Content-Type: text / cache-manifest
