   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).

   I haven't found any flaws yet

   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

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!

   Exactly the extension i was looking for. This should also be a Firefox default!

   I am using this add-on along side Containerise and its one of my favorite combos now. Works great for my purpopses.

   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...
