By default, Firefox and Thunderbird save their files to ~/.mozilla and ~/.thunderbird.
I am wondering if there's an environment variable I can set, to have either of them save their data to a different location. I want to have multiple instances of them available, each with their own settings for server and application testing. I can do this with the-no-remote option and Profile Manager of each, but I was wondering if I could totally keep the testing profiles separate from my main configuration.
This would also enable me to keep the profiles in source control if I so desired.
