Just installed, but seems to work nicely. One improvement I'd like to see: tabs listed within each container (i.e. below the container name itself) should be indented slightly so that it is easier to see what my active containers are and what's in each of them. Alternatively, outdent the container name itself (basically the same thing).

It does what I was looking for. All the tabs in the corresponding container and easily accessible from the sidebar.

A true revolution in my browser usage.
I wish 2 things might be adjusted, though:
a) Put the active container name at the end of the Titlebar so we know where we are when using the auto-collapsed setting, and
b) add 5-10px padding to the right side of the sidebar as it happens all the time that one click on the pop-up scrollbar instead of hitting the expand icon.
EDIT: (unchanged: original text/comment above is from 2022, 2 years ago)(still 5 stars from me)
c) Now (2024) that the following has been fixed in the new Firefox v.123;
https://bugzilla.mozilla.org/show_bug.cgi?id=1333395
(Conta
more
iner tabs sort order),
- it seems that this addon can now be updated to allow us to re-order the containers?
That is the missing part here, really need to be able to (re-)order the containers.
d) FYI: I am happily using the following custom CSS with this addon, giving nice coloring, contrasts, highighting of the current/active tab, and spacing. I think that something like this could be included in the addon as either a default suggestion, or in the text explanation above that CSS field for people to easily copy/paste into that field.
/** :root { --padding: 0.45em; }
body { font-size: 0.9em; }
Ref..: https://github.com/maciekmm/container-tabs-sidebar/blob/master/src/sidebar/style.css
**/
body { background: maroon; }
.tab-active {
background: maroon !important;
}
.container-tab {
background: green;
margin-left: 15px;
font-weight: bold;
}
.container {
padding-right: 20px !important;
font-weight: bold;
color: black !important);
}
.container-tab-close, .container-tab-close:hover {
position: absolute;
background: #333;
border-radius: 20px;
padding: 2px;
left: 2px;
top: 50%;
transform: translateY(-50%);
}

This is great. Works perfectly and the setting to use custom CSS allowed me to make it look exactly how I wanted (needed the container tab indented to make it easier to differentiate container name and tabs)
.container-tab { padding-left: 40px }
Thanks for creating this and sharing it!

I really like the addon, the text was too small for me. But with the custom CSS I was able to increase it. @Developer. Is there a CSS I could add to increase the size of the 'pinned icons'? If I would be able to make those bigger, it would be perfect!
EDIT: thanks for the response below. Worked perfectly. Maybe it would be nice to include some sliders for the non techies :)

Hello,
you can achieve this via:
```css
#pinned-tabs .container-tab .favicon {
min-height: 30px;
min-width: 30px;
flex-basis: 30px;
}
```
Thank you for your kind review!

Should be a part of default Firefox compilation/build/release.

Would be helpful if it showed the tabs of ALL FIREFOX WINDOWS. But it only displays tabs open in the current window, which is useless because you can already see the tab names at the top...

This addon would be perfect if I could select multiple tabs in the sidebar by shift or ctrl clicking.

Great addon! Thank you!
Added: Color bars appeared again in version 96.
Please pay attention, that color bars on tabs are no longer visible in the latest FF proton interface.
Added: I'm running the latest release - 91.0.1. Maybe the problem will be solved when 93 come to release.
More detailed description:
Previously there was a color bar above each non-default tab. Now the color bar disappeared, only the color frame around URL box is on its place.
I'm talking about the blue bar above the "New tab" on this screenshot taken from another container addon: https://addons.cdn.mozilla.net/u

Hello Max,
I am running Firefox 93.0a and see color bars on containers. Could you describe in more detail the issue you have observed?
Thank You for the review.

Edit: Thank you for fixing Temporary Container tab cycling!! It works for me now. I'm totally not about #2, I think that extensions has issues and there are alternatives that work with Container Tabs Sidebar.
I really like this add-on, but theres a compatibility issue holding me back.
1) The "Cycle tabs in view order" option is incompatible with the "Temporary Containers" add-on.
Specifically trying to drag-and-drop sort any tabs in the sidebar under the "Temporary containers" group causes them to snap back to their original position. Tabs in other containers dont have this problem, even w
more
ith Temporary Containers still enabled.
2) Much, much, less important to me, there is an issue when the UnloadTabs add-on is present. I'm not sure if this is actually Container Tabs Sidebar's fault.
When the UnloadTabs add-on is installed the tab focused after closing a tab becomes essentially random. While trying to fix this, I saw in the reviews for the add-on "Select After Closing Current" that it also also has a conflict with UnloadTabs present.

Good morning Kliff,
I have fixed issue #1, I'll take a look at #2, but it's pretty low priority as of now.
New version should be out now :) Please update and report your findings.

I prefer this lightweight addon compared to tree-style-tab and sideberry. Just the right amount of features and customization. Congrats on a great extension. I hope you don't bloat it!

Just like Tree Style Tabs, minus the Trees and plus the containers.
