Great add-on, keeps me using Firefox Rated 5 out of 5 stars

The main reason I use Firefox is because vertical tabs nurtured my tab hoarding habits. No other browser has descent support for this feature.

When vertical tabs and tab center were gone, I thought I would have to start being reasonable and close my tabs. It was a scary thought, but quickly this guy came for my help.
Now I can hoard in peace again.

I just wish we could hide the top navigation without .css hacks, but I understand it's a browser limitation.

I added custom CSS

#tablist.shrinked .tab {
height: 25px;

Great functionality! Rated 5 out of 5 stars

I'll give 5, but one bug: Top tabs are also visible
and one feature suggestion: 2 or multiple rows for the tabs if there are so many that they need to be scrolled?
Thanks! I can finally read what tabs really are open.

Is there a way to: Rated 4 out of 5 stars

Few UI improvements Rated 5 out of 5 stars

1. Is there a way on search to open the first match on ENTER? Is tricky bring the mouse again to open the result.

2. It will be very handy to have an shortcut.

Perfect and simple-to-use side-tabs solution Rated 5 out of 5 stars

I cannot imagine browsing without it. It also has dark theme, which is neat!

Although some icons in dark theme could be more visible. So after polishing that and after Mozilla implements said tab toolbar show/hide API, this extension will be even better.

Not ready for prime time Rated 3 out of 5 stars

Difficult to configure for those who don't know CSS.
How to hide/show tab bar is not very intuitive.
Can't drag-and-drop a URL onto the tab bar.
Adjustable width via splitter would be nice.
CRITICAL: Context menu is missing "Undo Close Tab"

EDIT: Ctrl+Shift+T will undo a closed tab, but a menu entry would still be nice.

Good but leaves tabs at the top Rated 4 out of 5 stars

Was hoping it would replace all the tabs at the top with just the side bar but it leaves them at the top as well. works great for me otherwise

Great interim solution Rated 4 out of 5 stars

Loved original Tab Center, despite it's flaws, so was disappointed when it stopped in labs, even more when it broke completely after update to ff56. This helps. It's not perfect, but will require help from the firefox dev team to fix, and in the mean time, it' s (much) better than nothing. Thank you.

Love it! Rated 5 out of 5 stars

One of my favourite add-ons for Firefox. Works brilliantly. Especially if you're that person with quite a lot of tabs open.

Superb Rated 5 out of 5 stars

Keep up awesome work

shortcut Rated 4 out of 5 stars

so far the best substitute for tab groups i've found. would love to be able to set a shortcut! thx for your work. & of course, eventually trees would be cool.

Not a real Tab Center Replacement Rated 3 out of 5 stars

Works well, but is not a real replacement for the original Tab Center Testpilot add-on. Tab Center Redux is just a sidebar like your history or bookmarks sidebar. It cannot auto-hide, doesn't remove the tabs at the top of the browser, and it must retain the sidebar switcher above the "New Tab" button. It's not the Dev's fault, but it really isn't as elegant as the original. If you just want a box that lists your tabs on the side of the browser, this works just fine.

Thank you Firefox. Rated 5 out of 5 stars
