Allday Tasks

Thunderbird (up to version 150) lacks the ability to create and manage allday tasks. This add-on adds these capabilities.
Thunderbird 151 has native support fpr all-day tasks, which makes this add-on obsolete!

TN Thread Order

Rated 1 out of 5 stars

by Günter Gersdorf on June 19, 2026 ·

- No english localization
- Does not work in table view
- If a thread contains subthreads, their messages may be mixed up, as the add-on only sorts messages by date and ignores relationships.

This review is for a previous version of the add-on (1.0.0). 

FolderFlags

Rated 5 out of 5 stars

Version 1.4.2 runs on TB102 with one small issue: Clicking on 'Flags' shows the quota and clicking on 'Quota' shows the flags.

This review is for a previous version of the add-on (1.4.2).
