I and also all other FireFox using members can't logout from and when we load the site, we mostly see older content instead of the new one. The behavoir come up wit FireFox v77 and we can reproduce at the above named sites eg.
The FF Dev-consol gives me no hint what kind of problem FF with this site has.
Other Browsers, like Chrome or Edge render the site with actual content and login/logout is without trouble possible.
So I come to my question: What can be the problem, that FF not render the newest content at this sites and let me not logout eg? I have no right idea, what we can do, that FF will be happy with our sites as bevor v77. What can I do to found the problem and what to fix it?
Both sites uses Xenforo 1.5.28 (latest), PHP 7.3.x, MariaDB 10.x, Redis Cache server side
I hope anybody can give me a hint, so I can do my best to solve it.
Best regards, Joachim
