I've used TST for years and this seemingly does everything I used that for, but smoother and with better options (at least for my use case). Some reviews on here confuse me because they describe issues that are blatantly not a problem in my experience but perhaps a few months back this was far worse or something. As of now, I have nothing to complain about so far. I will happily edit if I run into issues after long term use but I am very impressed as of now.

LOVE BLACKBERRY~!

I really don't get the hype around this extension.
The panel-system can be userfriendly but that's about all. Bookmarks looks a bit friendlier but don't even have a research function - useless when you have thousands of bookmarks. Icons don't load properly too. You can't shut the "Default" panel away...
The settings are just full of features which are unnecessary like scrolling through panel, auto-switch to panel on bookmark click, times in millisecond for smth to open without a click... What the heck? What's even the point of that?

Trying this out in place of TreeStyleTabs. Digging it so far. It looks/feels more modern than TST but provides similar functionality. I love that Bookmarks were incorporated into the UI.

A couple of small gripes. 1) Context menus are filled with icons (without text) by default. I found it frustrating to have to hover over these to read the titles. 2) Can't rename/delete the default Panel.

A blessing! Thanks for all the configuration options! Can make setup a bit more tedious - but on the other hand: it is so much more powerful!

Great !

Feels nicer than Tree Style Tab and lets you turn off tree mode, which I find leads to tabs piling up and being forgotten.

My main issue is that it often moves all your tabs back to the default panel on startup. From GitHub it seems this is a known issue at least.

Really useful tab manager.

It has a lot of settings and functionality, but it only shows up when you need it.

not really anymore useful than default firefox...

I was a Tree Style Tab user for 12 years. The first time I tried Sidebery I reverted back to TST. But recently the number of tabs I open put it under pressure and I finally switched. For me Sideberry is way more smooth and responsive than TST, way more configurable and doesn't get in your way.

Best All-In-One tabs manager + Groups manager + Containers manager + Bookmarks. Thank you so much.

Very, very nice. I used TST sometimes, but this presents the configuration in a much nicer way and all around looks better. I also love that bookmarks are built into the same panel here. This feels much more like an actual FF addon. Add in auto-hide sidebar CSS and this is perfecto.

Reading the neurotic 1 star reviews is truly a guilty pleasure. Schadenfreude of the highest degree. You people need to log off the computer for a few months and take a walk outside ;)

Looks gorgeous and replaced Tree Style Tabs for me.

I love the little loading and loaded swoosh animations.

I use Sidebery primarily to manage tabs, of which I typically have many open. It seems to do a mediocre job of this. Here are the functions I use and my experience with them:

1. Move tabs within a window. For some reason, Sidebery's drag and drop is terrible. Usually, when I drop the tab on its new position, nothing happens. It typically takes 4 or 5 tries before anything happens. It's definitely easier to use Firefox's tabs than Sidebery's.

2. Tab Organization. Sidebery does support tree structure on the tabs, which allows for some organization. However, it feels awkward to use because of the drag and drop problem. Also, there's no way, as far as I can tell, to mark or label a tab or group of tabs, to make it easy to find later. Overall, a weak implementation.

3. Move tab from one window to another. Again, Sidebery has a problem. After a length of time, Sidebery "forgets" the titles of my windows, and shows only a generic list. To get the titles back, I need to shut down Sidebery and restart it. Unfortunately, this is pretty much every time I need to move tabs, which is fairly often.

4. Search for a tab. I haven't been able to find a way to do this with Sidebery, so I just use the Firefox feature of entering % in the search bar of a new tab.

Many users have given Sidebery 5 stars, despite it being a very mediocre
extension.

PLEASE do not rate this extension highly for no reason!

I wish people wouldn't hand out stars for nothing. It pollutes the Firefox extension ecosystem with misinformation, making it hard to shop for good extensions. This extension is not worthy of 5 stars, or even 3 in my opinion.

Because it still seems to be under development, I gave Sidebery 2 stars, which I think is fair and in fact charitable. If it hasn't improved in the near future, I'll lower this to 1 star, which I think we should all do.
