I am guessing personal folders means folders you created under the Local Folders account. Items under Local Folders are on your local drive. To access them would be like getting access to any other file on your computer and would require remote access software like PC Anywhere. Installing that software on another computer that is not yours would be a bad idea. If you want to see all your folders from your providers webmail page you need to use IMAP protocol instead of POP and keep all folders in the IMAP account on the providers server. It has nothing to do with Thunderbird.
