Browser.cache.check doc frequency
Background
When a page is loaded, it is cached so it doesn't need to be downloaded to be redisplayed. If the page changes after a previous visit, you may want to redownload it anyway to get the updated page. This preference controls how often to check for a newer version of a cached page.
Possible values and their effects
0
Check for a new version of a page once per session (a session starts when the first application window opens and ends when the last application window closes).
1
Check for a new version every time a page is loaded.
2
Never check for a new version - always load the page from cache.
3
Check for a new version when the page is out of date. (Default)
Caveats
- browser.cache.disk.enable or browser.cache.memory.enable must be set to true for this preference to work as mentioned above.
UI
