I have an html5 manifest hello world set up with a page

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

and the manifest

<?php header('Content-Type: text/cache-manifest');?>
CACHE MANIFEST

CACHE:
/dummyjs.js?asd=1
...

it works on chrome but it doesn't work at all on firefox (ubuntu), I checked the server log and firefox does not request manifest.appcache after it gets the page, I read this answer and I checked if the server is sending those headers but it seems it doesn't (here request and response headers)

The interesting part is that it does work on windows, both ubuntu and windows have the latest version but firefox ignore the manifest attribute on ubuntu. I'd appreciate any suggestion.

1) Check if the no-cache/no-store headers are set.

2) Change content-type for .appcache files to text/cache-manifest. For Apache:

AddType text/cache-manifest .appcache

3) You can try to force the cache update by javascript:

var appCache = window.applicationCache;

appCache.update(); //this will attempt to update the users cache and changes the application cache status to 'UPDATEREADY'.

if (appCache.status == window.applicationCache.UPDATEREADY) {
  appCache.swapCache(); //replaces the old cache with the new one.
}

Well, this is embarrassing. I had "never remember history" set in preferences -> privacy under History, and that was inhibiting firefox from even request the manifest. Ouch.

  • Can you elaborate on what "don't save chronology" means? I'm experiencing the same issue and can't track the problem down. – Aleks G Oct 28 '14 at 12:01
  • Sure, in preferences -> privacy under History I set "never remember history", if I can remember correctly this was my problem, please tell me if it solved your problem too so I can update the answer – lelloman Oct 28 '14 at 12:06
  • Thanks. Unfortunately, it's not the issue in my case, as I already have "Remember history" set. – Aleks G Oct 28 '14 at 12:22
