old .mozilla folders (newbie query)

Is it safe to put my old .mozilla and .mozilla-thunderbird folders from xandros 4.2 into OSS 11.3? I have apps, emails, and settings that I would like to keep. This might seem like an over precautious question, but I’ve broken Xandros more than once. I would hate to do it to OSS. Thanks in advance.

I have never had a problem keeping $HOME/.mozilla

In any case, there is no harm in trying. If you finish up with a corrupted browser, then simply “rm -rf .mozilla” and let it build a new one.

You could even use the Mozilla-folders from a completely different system (for example Windows) and it will work.
