I did reset firefox but nothing changed + run malware adware and antivirus ; as said above it also happens with IE on my desktop and on firefox android with my tablet (sync with desktop)
Go to Solution.
You can try to reset (power off/on) the router.
Are you using a proxy or a direct connection?
Check the connection settings.
If you do not need to use a proxy to connect to internet then try to select "No Proxy" if "Use the system proxy settings" or one of the others do not work properly.
See "Firefox connection settings":
Many thanks cor-el,
I discovered that since I connect direct choosing the no proxy option has solved the problem; Hoping I am not speaking too soon...
