From what I can see by looking at the corresponding Bug (Bug 640904), this crash has been fixed on the Aurora and Beta branches, thus it should be fixed in the next major release.

You can try out the next Firefox 14 beta 8 release later this week that may include this bug fix (Bug 640904) or else beta 9 a week later.

You can install multiple Firefox versions via a custom install in different installation folders and only use the older Firefox version when you really need it. Do a custom install and install each version in its own program folder to use multiple Firefox versions.

Make sure not to start Firefox after the installation has finished. Create a new profile exclusively for each Firefox version. Create a desktop shortcut with -P "profile" appended to the target to launch each Firefox version with its own profile.
