I loved having the autohide tabs on the side and no tabs at the top. It was just easier for me when I was search for something, say Thumb drives, and I could easily locate the store page from all the listings I was looking at. The autohide tree tabs on the side gave me more screen space both vertically and horizontally and I miss it sorely. I hope to see this updated soon for ff57!

Auto hide not working in FF57 & display as sidebar! And horizontal tab too displayed.

My favorite extension. Works great with Firefox 57+. It has many options and also allows customization via CSS (I use it to increase font). It doesn't hide top tab bar because of API limitation but for me it is feature not bug :) because I sometimes use also top bar for example when I need more horizontal space.

The reason why I continue using Firefox. Viewing pages in a tree is a great way to keep track of my day-to-day projects.

Such a lovely way to view tabs!

Not working in firefox android version 57 (2017.11.15)

Great way to organize tabs if you're a million-tab user like me.
One request (and I know it's early) - in Firefox Quantum, the tab bar at the top stays! So now I have 2 sets of tabs - the normal Firefox tabs, and the tree style tabs. Would be great if there was a way to hide the tabs at the top. Thanks!

This extension is the one of the main reasons I continue to use Firefox instead of Chrome as my primary browser. However, I don't like the new looks for Firefox 57. I don't want to see the "Tree Style Tab" block at the top of my list of tabs, I only want to see my tabs. I also want to get rid of the new-tabs button at the bottom of my list of tabs. I also don't want to see tabs horizontally across the top bar of firefox when TST is open. I still love the extension, and it feels a lot less buggy than it did before 57, but I want the appearance to be decluttered and get out of my way more like it did before.

This is the best extension ever. I would also like to be able to hide the tabs at the top in Firefox 57.0.

Can't imagine browser without this addon.
The main reason why I'm still on FF.

Great extension. Don't know if it's possible with Quantum limitations to add an option 'Protect tab' (from accidental closing)?

Great extension, but in Firefox 57.0, the tabs are still shown at the top of the browser, taking up space – I hope this gets fixed soon!

This is probably the main reason why I use Firefox!

This is the mother of all "killer apps" for all browsers. I've used tree-style tabs for years now, a great surprise that it was updated as a webextension. Firefox Quantum + tree-style tabs feels like the future. Bravo Piro!
