Rated 2 out of 5 stars

The extension does what it promises, and does it nicely.

However, it has a nasty side effect (at least with me). I use multiple accounts and as such have multiple inboxes, sent folders etc. Only one of them is threaded, the rest is just sorted by date and some are then grouped by sort.

But after installing this extension all my folders become threaded. I can switch them back to unthreaded or grouped by sort, but after I receive another e-mail for that folder, threadbubble forces it back to a nicely sorted threaded view.

(ThreadBubble 0.6 with Thunderbird 2.0.0.14 on Windows XP SP2)

Update: Followed the advice to disable all other extensions. Unfortunately this had no effect. ThreadBubble still keeps threading inboxes that should not be threaded. I think it appears only to happen when you receive an e-mail for the folder you're currently viewing.

This review is for a previous version of the add-on (0.6). 

Hi Frank, I have several folders and accounts and ThreadBubble only affects one of my inboxs (the threaded one). I'd suggest disabling any other extensions you have and trying again. No one else has reported this problem (which also makes me think it's another extension doing it) but if other people see this please let me know. Thanks.

I'm using Thunderbird 2.0.0.14 on Linux (don't have XP to test it specifically).
