in short, no....

The only way to do this is on the client itself. You can then change the user agent string and that is about it.

Other than that, this is why W3C exists, it stops headaches like this.

Another option would be to install an older version in a virtual machine, however I wouldn't waste too much time trying to install anything older than 3.5 as firefox is now pushing updates automatically like chrome does, and they've stopped supporting anything before 3.5 or 4, I believe.  YouCOULD try installing previous versions side by side Bu t you HAVE to keep separate profiles and point each version of firefox to the separate firefox profiles.  And you can't run them simultaneously.  I believe Firebug add-on may help you as well.
