I need Firefox version 8 to test on for contract requirements. How do I get that version and can I run it concurrently with the latest version?

Our contract for elearning development specifies (among other browsers) Firefox 8 as a target browser to display the course. I have the current version of Firefox installed on my PC. (Windows 7) Where can I get a copy of Firefox 8 to use for QA testing, and can it be installed and run concurrently with the latest version I have now?

Using an older version of Firefox is a security risk. However, use discretion when you do plan to use an out-of-date Firefox version. You can find the Firefox 8.0 download here.

Can it be installed and run concurrently with the latest version I have now?

Yes, if you choose a different installation path for the Firefox directory (e.g. C:/Users/USER/Desktop/Firefox8). You need to use the -no-remote command line switch to open another Firefox instance with its own profile and run multiple Firefox instances simultaneously. (Right click the new Firefox.exe and add -no-remote to the Target Path)

Hello,

you can also try the portable one, and as the-edmeister said

"...You can launch the "Portable" versions from the desktop shortcut, no need to edit the Target: line. No need to mess around with "Profiles"..."

Firefox Portable 8.0.1

Firefox Portable 8.0

Thank you

Why Firefox 8.0 specifically? as it was made EOL when Firefox 9.0 release came out back on December 20th, 2011. While a minority do stick with old versions for various reasons it would be odd if there were that many using Firefox 8.0 compared to any other Release.
