hi, first please make sure that the date, time & timezone are set correctly set correctly on your system.

if this doesn't solve the issue (or it is already set properly), this might indicate that something on your system/network is intercepting secure connections - a solution depends on the individual circumstances:

• what is the error code shown when you click on advanced on that error page?
• please also give us more information about the error by clicking on the error code, copying the text to the clipboard and then pasting it here into a reply in the forum like shown on the screenshot.

thank you!

Of cause time and date is valid. It is my job laptop. All synchronized with server. The problem with FireFox started after last auto update. All other browsers continue process well. No changes also in firewall or other programs.

thanks, so in a corporate environment it appears that all your secure network traffic is being intercepted/monitored by some network appliance. in order for that to work, the certificate of the man-in-the middeling device has to be trusted by browsers. firefox uses its own trust store for certificates instead of depending on the windows trust store by default.

you could import all custom certs from windows into firefox like this, which in effect should address the erros on secure pages: enter about:config into the firefox address bar (confirm the info message in case it shows up) & search for the preference named security.enterprise_roots.enabled. double-click it and change its value to true and restart the browser.

Thanks. Now more good. All works. Why do you do it parameter false? So you lose your customers.

I am an old person who can normally handle computers - if you are a geek, perhaps I could understand it - bye Firefox
