I have a large file that is quite slow to download (200mb or so). I'd like to be able to quickly configure Firefox to cache the file and save it every time it needs to access it, so it doesn't have to re-download every time.

I've tweaked the settings in about:config and in Options->Advanced->Network in the following way (see attached for about:config settings):

Override automatic cache management (enabled) Limit Cache to 1000MB of space.


I'm pretty sure the cache settings in Options-> Advanced -> Network are fine, but for the about:config settings, I know that changing some of them is important, but I'm not sure which ones. Can anyone tell me which ones I should change? I've had other people change settings on their machines the same way, but my ram and processor are different, so these settings caused Firefox to crash for them. I'd like to know exactly which settings to change and why.

Thank you!!

Is the file a download or a cached page? This add on automates checking a page if it changes, but it runs in set intervals to check for changes: https://addons.mozilla.org/En-us/fire.../check4change/ and this one is a bit similar: https://addons.mozilla.org/en-us/fire.../update-scanner/

I do not know how this would work for downloads since these are not stored in Firefox explicitly.

I assume that you need to increase the value of this pref from the default 51200 to -1 (no limit)

  • browser.cache.disk.max_entry_size

Note that you may be out of luck as big files may not be cached unless you adjust browser.cache.disk.capacity as well (don't know if there is a maximum for cache2). 

62 // Max-size (in KB) for entries in disk cache. Set to -1 for no limit.
63 // (Note: entries bigger than 1/8 of disk-cache are never cached)
64 pref("browser.cache.disk.max_entry_size",    51200);  // 50 MB
