Filter email folders
Filter mail folder tree by keyword.
For those with many folders.

Hide Duplicates From 'All Mail'
Hides duplicate emails from the 'All Mail' folder upon clicking on a result from Global Search, so that if one email is in both the 'All Mail' folder (e.g. of Gmail) and another folder (e.g. 'Sent'), it'll only show the email from the other folder.

This add-on is superseded in TB78 by the built-in folder-color changer (in folder > Properties).
To create your own collections, you must have a Mozilla Add-ons account.
