Doesn't remember tab locations properly after restarting, making this useless.

There is no help page, no beginners guide, nothing. It took me a lot of trial and error to do anything at all and have no idea how to get it to handle bookmarks.
I searched the web for a beginners guide but found nothing.
If I ever find such a guide, I may give it another try.

This is not first time that after closing and opening the browser, all tabs are lost. Very unstable add-on. Not suitable for work.

Ce n'est pas dans ma langue

Deleted 800+ of my tabs

It's a broken mess.

There is no obvious way to show bookmarks in the sidebar. I searched for about 10 minutes and could not find an option to show the bookmarks. All I got in the sidebar was tabs—which I definitely did not want to show in my sidebar. Moreover, even it I were able to located the setting to install my bookmarks in the sidebar, I do not believe I would be able to with one click open a sidebar with my bookmarks showing. Apparently I would have had to click on the Firefox sidebar icon, then to click on the Sidebery icon. That's not acceptable. Is it unreasonable to be able to make one click to show a sidebar of bookmarks?

What is the point of this? Theres folder, but then the tabs are all still in full view in the bar. It sounded like it would function like chrome, where you can open and close the folder, so as to, ya know, organize your tabs??? and not have 15 open ones cluttering up the bar? Useless extension

When I open it, I want it to default on 'bookmarks' not 'sidebery'. I'm not going to spent all night with my head buried in Settings trying to figure how to change the default.

Started OK, went well for a couple of days, then just disappeared! Re-installed, no show. Forget it, not worth the hassle!

It started out ok but several times now I start Firefox and all my groups are empty, and instead, all tabs are just listed in one window, hundreds of them! what a complete waste of time. I spent hours fixing it only to find several days later it had done it again. I did some searching and found this is quite an old bug and seems to be has never really been resolved. Stay away from this extension if you value your links

Rotding brengt alles in de war, waarom de systemtray, hoe raak ik dat kwijt, config is een jungle.

Since the last update, this app is clunky, slow, and frequently crashes (the biggest crashed my whole system) with no way to retrieve my previous loaded webpages. After uninstalling the extension, I no longer have access to the usual Firefox browser - the tabs are gone and only accessible from "List all tabs" menu, also, new tabs can only be opened using the "Application menu".

Make setting for default panel (bookmars or tabs or ...). I need bookmarks, but it allways open tabs first.

If you shift-click select in a search filtered view it selects tabs that aren't shown due to the filter. How did anyone think that was a good idea? User hostile design choice

It looks good but how do I hide all the tabs at the top of my browser?

Doesn't work across multiple windows, which makes the entire extension useless to me. (every window acts as a completely separate instance with separate tab groups)

Someone recommended this as a replacement for Simple Tab Groups, which it definitely isn't because of this.

It looked fantastic, until I got no scroll bar and more tabs than fit vertically :( Thank you anyway, it probably works fine elsewhere.
