User-Agent: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.7b) Gecko/20040316 Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.7b) Gecko/20040316 Installation of 1.b over 1.7a resulted in me losing all my mail, bookmarks and settings. I hadn't expected this type of behaviour from Mozilla. I wasnt even given a warning. The data is completely lost: I cant find any trace of it on my system. Reproducible: Always Steps to Reproduce: 1. Install 1.7a 2. Make some bookmarks, settings and mail accounts. 3. Install 1.7b. All of the above will be lost. Actual Results: Installation seems unaware of existing installation. Expected Results: It should have detected an existing installation and warned me of the results at least. Ideally it should have saved all of my settings (exported them), and upon installation prompted me to reload them (optionally).
You can't find it under c:\documents and settings..\ ? (note: one directory is marked "hidden" and you must enable "show hidden files" in the Explorer)
You weren't given a warning??? http://www.mozilla.org/docs/end-user/guide/get-started.html#previous-mozilla
If you set the Mozilla install directory as the custom location for the Mozilla Profile, then this is expected behavior when you OK'd the deletion of the the contents of that folder in the Install wizard.
