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.
