ConfirmFolderMove

ConfirmFolderMove came about because trackpads tend to pick up unwanted movement, including accidentally picking up a folder of 20,000 messages and shifting it somewhere it shouldn't be. It takes a long time to fix that kind of accident. confirmfmv pops up a dialog window before doing any moving, stopping the move if cancelled.

You can turn off the preference (folders.drag.confirm) within the extensions window in case you plan to move a lot of folders.

Download

Please use the Mozilla extensions page to download (12KB, version 1.0); open up the extensions window in Thunderbird and install the downloaded XPI file.

If for some reason the Mozilla page is not available and you must procure this extension, you may download it from me. Thunderbird will still phone home to Mozilla resources for auto-updating regardless of where you acquire the extension.

Version Notes

0.3: Added new preference to disable all confirmation dialogs and a German localization, thanks to Dennis Plöger!
0.2: Metadata compatibility for later minor releases; no functional changes
0.1: Initial release.
