Almost forgot; the error message is "Could not find mozilla runtime."

hello, can you try to type this address into the address-bar of windows explorer (the file browser) and download the appropriate firefox version for your language?: ftp://ftp.mozilla.org/pub/mozilla.org/firefox/releases/36.0.1/win32/

If you have access to another computer (e.g. via a friend) then try to download the full installer and save the file to an USB stick. You can find the full version of the current Firefox 36.0 release in all languages and for all operating systems here:

• https://www.mozilla.org/en-US/firefox/all/

Another possibility is to open the Mozilla FTP website in Windows Explorer and download the Firefox setup file that way. See "How To Download Firefox On a New Computer Without Using Internet Explorer":

Philipp:

Worked like a charm; and the very first time. Thank you very much.

Cor-el:

Sorry; I wasn't able to try your solution. Thanks for writing anyway.

This is a problem with Norton and not the Firefox browser with Norton's claim of Suspicious.Cloud.9.

It has been doing this Suspicious.Cloud false positive with SeaMonkey for years every so often and Norton has not bothered to fix it. Norton antivirus would claim a virus is in file freebl3.dll only there is not and never has been.

It got to be such a regular occurrence that they even single out Norton in the Known Issues of SeaMonkey Release notes for some years as can be seen in http://www.seamonkey-project.org/releases/seamonkey2.33/#issues and will be listed until Norton finally fixes it.

Posts about the Suspicious.cloud claim with Firefox here (and at mozillaZine) have been infrequent compared to SeaMonkey.
