Can I run 2 separate versions of Firefox on my Mac with OS 10.6.8?

For example, I'd like to run my current Firefox version 5.0.1 with the new version 6.0 so that I can easily switch to the older version if something doesn't work with the new version. I run the 1Password extension with Firefox and I got a message the current 1Password 3.7.1 doesn't run on Firefox version 6.0. If so, that's a killer for me and I will not upgrade to Firefox 6.0 until there are compatible versions of both. THANKS! -JStar510

For Reply 1: Thanks, but I'd rather pass on beta releases. Plus the basic issue has happened before and I suspect it will happen again.

For Reply 2: Excellent! That's exactly what I'm looking for. I'll try it tomorrow and let you know how it goes!
