I have tried it, but I like the standard look. Easy to follow in standard. - Bryan R. Adams

I've been trying to use it but it bugs out on me and just stops updating. Then I end up having to refresh again which defeats the purpose. - Andrew Trinh

I gave up because I end up missing a lot of things when it randomly decides to stop updating. - Rah-PM 2012

I don't use it. It's too hard for me to follow. - Rochelle

I like the pop-out functionality - Mattb4rd

Loving it I'm afraid, I've put it in my Firefox sidebar. I need a FF patch to wean me off it ;) - Glenn Slaven

Meh. - Victor Ganata

blah. twhirl FTW - takes up too many resources, which FF already eats enough of - Enrique Gutierrez from twhirl

Didnt like it either, meh - Sally Church

don't like it. needs a focused mind. especially bad if following many people. - Bora Zivkovic

I think unthreading the conversations really defeats the purpose of FF. - Victor Ganata

This is just for conferences! : ) - Erhan Erdoğan

I have it in my FF sidebar. It's great. Doesn't replace the tab with FF always loaded, but makes a nice supplement. - Tinfoil 2.0

It was up for days, but I closed it a few hours ago. I had a nine-minute deadline on something, and Firefox was being sluggish. I'll get it open again soon. - MiniMage, enterRUPPted

It becomes quite useful when you use it for a list like favorites on the Firefox sidebar, so that's how I'm it ... works great - Jay
