Firefox cache check frequency
I’m used to putting my laptop to sleep/hibernate, and often times, Firefox stays open in a single session, until I restart the machine eventually. However, I noted that some websites didn’t update automatically when their tabs were closed and re-opened later on, and that a click on the refresh button was needed in those cases.
To make cache work as it should when Firefox is left open for ages, modify the browser.cache.check_doc_frequency setting in about: config. Its values can be set as follows:
0 – once per session (default)
1 – every time
2 – never
3 – automatically
Changing the setting to 1 does the trick.
