Session variables sometimes not set in Firefox


i have a strange issue with my site under Firefox.
Does kirby save the s::set variables in a cookie or somewhere else?
Sometimes my values are not set especially after reload the page the value i’ve set with s::set is gone and contains the value it has before.
BUT not every time… after wild reloading multiple times it works…sometimes.

any ideas what goes wrong?

under Safari and Chrome it works every time, hmm… :frowning:

Have you ever been able to find an answer?

I’ve had some trouble with session variables only at this hosting provider.
Just ‘workarround it’.
