I adore this addon and have no complaints whatsoever!

Good old gem. Use TST+UserChrome+ TST AddOns where you cannot update Firefox for some reason.

Sorry to see it go: +6 years ahead of its time!

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.
