This is so NOT an answer. I have tried this twice and timed out on the big/main download at a bit over 50%.

Please start a new thread for your problem or question and provide troubleshooting information like your operating system and installed extensions and installed plugins.

• Firefox 6.0.x: http://www.mozilla.com/en-US/firefox/all.html
• Firefox 3.6.x: http://www.mozilla.com/en-US/firefox/all-older.html

For anyone trying to download the latest version of the full Firefox installer, go to this link where you can choose your language and version and can download the offline installation file: http://www.mozilla.org/en-US/firefox/all.html

If that doesn't work for you (non-US downloads), on the download page beneath the green box that says: Firefox Free Download, click on the link that says: "Systems and Languages" - this should take you to the appropriate page.

Good luck...
