Great extension while it is running, but each time the firefox is restarted it's a pain because all tab hierarchy is broken.

Need a feature to auto-backup and manually save/restore tree.

Très pratique

Feature-rich; lots of options to customize your workflow. Really excellent extension.

This helps browsing a lot, but it does have a few bugs. Right now, I'm experiencing a bug where the tabs have been slightly truncated, chopping off the favicons.

Very outstanding addon, but since 2 months it's super slow. When disabled Firefox is working fine. But enabled it slows so much down that Firefox is nearly unuseable.

cool function "close other tabs"
always got on her instead "reopen closed tab"
