I uninstalled and reinstalled Firefox this morning. Prior to the uninstalling, I went into the %APPDATA%\Mozilla\Firefox\Profiles\ folder via start, run and located my bookmarks. From there I copied and pasted the bookmarks to a flash drive. I then uninstalled Firefox and installed the newer version 3.5. When I copied and pasted my bookmarks from the flash drive back to the %APPDATA%\Mozilla\Firefox\Profiles\ folder, my bookmarks did not show up when I opened Firefox. I placed the bookmarks in the bookmarksbackup folder.
