Problem with latest version of mozilla

Hello,

since I installed the latest version of Mozilla, Firefox keeps me going longer access to any sites. It is connection failed, and so ..... What to do to solve this problem, thank you in advance

Try disabling your firewall. If ok, you must restore Firefox permission in the firewall.

I tried disabling it, it allowed into the firewall, nothing to do. With the Firewall i think

You thinking of an update. Should see it this way:

1. Uninstall Firefox from adding or removing programs
2. Delete the C: \ Program Files \ Mozilla Firefox it is always present (your profile, it will not be deleted)
3. Restart the computer
4. Install the new version offline after downloading the executable

I just did what you told me and nothing extra i did

Here is the message:

The connection has failed
Firefox can not establish a connection with the server at www.mozilla.com.

Although the site seems valid, the browser could not establish a connection.

• The site may be temporarily unavailable? Try again later.
• Other sites are also inaccessible? Check the connection to your computer.
• Your computer or network is protected by a firewall or proxy? Incorrect settings can interfere with navigation on the Web.
• You always have problems? Check your network administrator or ISP for help.

And more with all this, I can not connect to sites that I go before the problem with mozilla. (online casino sites)
