Mozilla has 4 channels. In order of less to more secure and stable: Nightly, Aurora, Beta, Release. On the page you reference, "Final Release Channel" refers to Mozilla's "Release". These are versions that have been completed and "pushed" out for download by everyone. The most current version is always available at https://www.mozilla.com/en-US/firefox/fx/ (currently, Firefox 6.0). There are only 2 currently supported versions: Firefox 6.0 and Firefox 3.6.20. *All other versions have stability and security issues that will not be corrected, but are corrected in the updated versions, as they are released. Other download links: *Current version (now version 6.0): http://www.mozilla.com/en-US/firefox/all.html *Older supported version (now 3.6.20): http://www.mozilla.com/en-US/firefox/all-older.html According to the chart on the page you referenced, your students should be using Firefox 3.6.20 (Firefox 3.5.x versions are no longer supported or updated). The certified/compatible classifications are Blackboard's determination. '''<u>Firefox Portable</u>'''<br /> If your students wish to use the most current version of Firefox for their everyday browsing and use a Blacboard compatible version for use only with Blackboard activities, they can have both on their systems by installing Firefox Portable (not produced by Mozilla): *Firefox Portable installs in a separate folder on your hard drive so that it does not interfere with your current version Firefox settings or personal information (bookmarks, passwords, etc.). Add-ons are also kept separate. *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...
