You can install Firefox Portable version 3.6.20 to use only on that site and use your installed current Firefox 6 for everything else. Firefox Portable is not produced by Mozilla (but is based on Firefox released versions) and is not supported on this site -- has its own support forum (see below). Firefox Portable installs in a separate folder on your hard drive so that it does not interfere with your Firefox 6 settings or personal information (bookmarks, passwords, etc.). You can also install Firefox Portable on a USB/thumb/pin/jump drive. *Firefox Portable general information: http://portableapps.com/apps/internet/firefox_portable *Firefox Portable 3.6.20 download links: http://portableapps.com/apps/internet/firefox_portable/localization#legacy36 *Firefox Portable user forum: http://portableapps.com/forums/support/firefox_portable '''If this reply solves your problem, please click "Solved It" next to this reply when <u>signed-in</u> to the forum.''' ------------------------- Not related to your question, but...
