Hi @pavloborysenko,
After disable all of my plugins, this problem persist.
But, I found this link : https://stackoverflow.com/questions/3536822/force-firefox-to-reload-page-on-back-button, that explain how firefox and chrome cache works.
I add this js code to force reloading page on navigator navigation click :
// Detect if navigator is firefox
if (navigator.userAgent.toLowerCase().indexOf('firefox') > -1) {
// Refresh page on navigator navigation click
$( window ).unload(function() {});
}
This resolved my problem.
Thanks for your help !
