it does not allow to set a title for each window. useless.

O "Tab Center Reborn" possui os mesmos recursos do "Tree Style Tab", com o diferencial de ter uma caixa de pesquisa para as guias, similar à extinta "Tab Center Redux", excelente.

This has been my favorite vertical tab solution for a very long time (and this review is long overdue).

How I use it: In TCR options, enable "Use current browser theme", "Compact Mode", "Favicon-only Pinned Tabs", and "Custom Stylesheet". In the stylesheet, in addition to some tweaks provided by the author (thinner scroll bar, hidden header-- see the link in the documentation), I also add "#topshadow,
#bottomshadow {
box-shadow: 0px 0px 7px 5px rgb(30, 34, 40) !important;
}" to darken the overflow shadow within the tab list. This color is very subtle and matches my favorite them, GitHub Dark Dimmed by evgnz.

Mozilla is finally working toward adding built-in options for vertical tabs, and I'll definitely be judging that implementation against this wonderful extension, as well as the great vertical tabs offered by Vivaldi.

This is the best tab add-on I have ever used. It has everything you want from a vertical tab add-on, and the inline tab search feature is brilliant when you have many tabs open.

the "Notify when closing many tabs" checkbox does not work and breaks the "Close tabs before/after/close other tabs" options, causing it to simply hide the tabs from view instead of actually closing them. works great otherwise.

Super le filtre... il faudrait pouvoir sélectionner et supprimer ...

J'ai testé plusieurs extensions similaires avant de revenir constamment à celle ci car elle est simple et non bugué après une maj. Le fait de pouvoir ouvrir un onglet en double cliquant est top.

The best vertical tabs implementation for Firefox I have come across. Kudos to the devs. I also wish Firefox weren't dragging their feet on implementing vertical tabs natively.

Although I used Edge for a while, I returned to Firefox after hearing about Microsoft's plans to move on to Manifest v3. If there's one feature that I liked from that browser, it was its vertical tabs, which are a more efficient use of screen space.

Going back to horizontal tabs felt like a regression, but this add-on almost brought vertical tabs TO Firefox; After hiding the tab list and replacing it with the title bar, Firefox feels somewhat more like Edge, which I find pretty neat!

Edge-to-Firefox migration story aside, this add-on is a good use of Firefox's sidebar, turning it into a list of any tabs that you have open. It looks nice, adapts to your theme (including ones made using Firefox Color), and at times feels like a natural part of Firefox itself.

Like another reviewer mentioned, tabs can't be grouped with this add-on, which is sort of bad, but I didn't use tab-grouping often in Edge, so not much is lost here.

In conclusion, if you prefer tabs that are listed vertically, are coming from Microsoft Edge, or want to experiment with a new UI layout, I recommend Tab Center Reborn! I've only used it for less than a day but it's mostly exactly what I was looking for.

If you could also group tabs like in Edge this add would be perfect.
