Are both browsers configured to use the same proxy?
What do HTTP headers of the content in both browsers say?
What do logs of squid say?

Note that browsers may have its own cache and can be configured not to
re-fetch the content in the same session.

Also, the content's HTTP headers may be broken, or configured to cache the
content for some time, which means browser won't re-fetch it even if it
changes (browser can't know if the content changed without trying to
re-fetch it, which may be disabled by HTTP headers)

change browser or the user-agent header?

of course it is not. never_direct configures behaviour in cache hierarchy
and does not affect caching of the content.
(this is quite common false assumption)

First I advise you stop playing with  refresh_pattern if you want to fix
your caching problems
