Hello, is this the standard behavior for downloading the FF by using some different web browsers? I am talking still about the same version of 64bit FF for Win10 offline installer US but downloading this in different web browsers... The (final) downloaded file has exactly the same size of file but "slightly" different content - this is happening only when downloading FF. If I download different browser in various browsers then the size and content is exactly the same - but not in case of FF. Is it OK (some adjustemnt..) please or could it be virus? Thank you in advance for your respond. Jiri

That looks like a ua (usragent) command line parameter for accessing google.com, one shows ua=chrome and the other ua=firefox and using different browser might explain the difference. You can check the code further ur up to see what this is about.

Please explain in more detail what you mean by "slightly" different content so that one of our support contributors can help you.

For the record, the Firefox 64-bit offline installer for Windows can be downloaded here: https://www.mozilla.org//firefox/all/#product-desktop-release See Custom installation of Firefox on Windows for more information.

Dear Alice, picture with differences can be seen below (in the attachment) - I was talking exactly about the link you sent me in your respond  ;o) One version was downloaded in FF, the other version in Opera Hopefully the picture will be sufficient for you (?) Thank you very much in advance. Jiri

Jiri, This forum is for getting help with Firefox issues and I don't understand the problem you are experiencing. Maybe someone else can help you, if not here then in one of the other forums listed in the Get community support article under Additional resources. You can also try filing a bugzilla report.
