Review for Hide Local Folders by tomsoms
Rated 5 out of 5 stars
Good extension. This extension is usefull for Thunderbird users that do not known how to use locale folder or do not want to use local folders.
Carefull that if you had renamed the "Local Folders" account name to something else you need to rename the account name back to "Local Folders" and then restart thunderbird to hide the account in the folder list.
To create your own collections, you must have a Mozilla Add-ons account.
