Great Addon, incredibly useful when doing research.
Thanks Prio for redoing the Addon for the new API!

@everyone who is complaining about the lost features:
seriously, it's not the addon dev's fault they changed the addon API. stop giving bad reviews!

I have been using this extension for years, and am very happy that a release for Firefox 57 was released quickly!

Firefox 57 has completely ruined this add-on. Highly unfortunate as I read online to see if there would be any issues before updating and it didn't look like it would be a problem.

1) Can we get an option to have «Additional Context Menu Items» not in submenu, but in main context menu just separated by separator?

2) Can we have options to disable «standard» menu items. Like I do not need «Reload All Tabs» and all other in this section.

3) Is translation possible for this menu?

The previous version of the side tabs could be narrowed or widened at my discretion. This new version does not allow that. The previous version removed the tab bar above the address bar, thus freeing up vertical display space. This newer version does not do that. Why the regression of capabilities? I have removed the addon until such time as an updated and more capable one is provided.

Best browser extension I have ever seen! I can't figure out why browsers haven't yet incorporated this feature into their browsers as a default feature. This browser extension is the primary reason I use Firefox and not Chrome. Thank you tree-style-tab developers! You're the best!!

All the right features. Saves precious screen space and my time.

ok

Well, it's the best work around so far until a true tab-grouping add-on is developed for FF 57. It's the whole reason I use FF. Wish you could label the parent tabs something else than the parent website. For example, "Everyday Stuff" or "Suppliers." We have several suppliers and different types of suppliers so it would be nice to label each Tree like the tab groups of 56.

The previous version had exactly what I was searching for, meaning the ability to group (and collapse) tabs together while remaining at the top like the default tabs.

I am using half-width windows all the time, so the side bars take way too much space for me, so sadly I had to disable it once firefox forced its update and new plugin versions on me, but I am still hopeful that one day it will give us that functionnality back.
