Thunderbird Conversations is a Thunderbird extension which, as the name implies, enables a conversation view in your Thunderbird. Notable features include:
- a regular conversation view that fetches messages from all folders, and behaves just like Gmail’s
- a quick reply feature, with autocomplete, that allows you to reply to a thread in a snap,
- quoted parts are collapsed,
- keyboard shortcuts,
- and a few other bonus features.
Don't forget to hit View > Sort By > Threaded in the menus. To remove the unified folder view, hit View > Folders > All.
We welcome feedback, but only if you've read the FAQ before :-)
