@Laura_Chambers I think it is awesome that your team is working on these features. I have convinced multiple people to switch to Firefox in the last few months, but I myself have been slowly using it less due to a lack of these features. If it is not to much to ask - would it be possible to get a split screen feature like in Edge? That would definitely enhance Firefox’s usability and make it more attractive to a wider audience. Also, I love the personalization features, but I think a few more would also appeal to more people (just my thoughts). Thank you so much for you and your team and I am really looking forward to what you come up with this year. Good luck and God bless!

I agree that this is a necessary feature for Firefox, and while everyone has valid opinions I think it’s important to implement tab groups in a way that’s not just copying chrome.
Obviously having as many options as possible is ideal, but it’s not me maintaining that so I wouldn’t ask for it. Panorama, while unloved, was distinct and I’d love for whatever is built to be innovative and not just playing catch up with chromium.
So glad this is finally coming to Firefox!
Since nobody has linked it that I can see, here is the vertical tabs idea voted on in Connect:
Hope we can get a two-for-one deal here!
Not that I think that a browser should primarily be for power users, in this case it is indispensable to anyone with a large number of tabs, and would be optional so no cost to casual users, and also it is very easy to go from casual use to accumulating lots of tabs (getting into uni or a job that requires lots of research, etc) so plenty will discover its value as they keep using Firefox.
Yes, at the very least, there should be an API to make the browser addons useful again. Now, not only is there no way to hide the tab strip, there is no way to easily access the sidebar containing vertical tabs.
Nobody has ever suggested vertical would be the default, but yes trees provide something horizontal tabs never can: clear visual context of where a tab came from.

VERY happy to hear this feature will come to Firefox.
I have only one wish how it should be implemented:
One way to collapse and expand the tab stacks should be double-clicking on the stack.
That’s all. This way is so fast and convenient. I feel very strongly that this is THE best way to expand/collapse the stacks. This needs to be there as a far as I’m concerned.
I would also encourage the developers to study how the original Opera browser implemented this feature. Still the gold standard in my opinion.
I’m very happy to know that Tab Grouping will be coming to Firefox, this feature is very mandantory for Google Chrome users who want to switch to Firefox.
Thanks very much for listening to the userbase, let’s make Firefox great again!

Any chance that means we can get confirmation on vertical tabs too??
It’s easy to accumulate a lot since bookmarks feel too permanent, tabs are nicely ephemeral and can be treated like a long to-do list.
Might be nice to blur the lines a bit…

Definitely! I couldn’t agree more. The split screen view on Arc Browser feels like a game-changer. It’s incredibly refreshing. Being able to split any tab or link directly from the context menu is a real time-saver. From a productivity standpoint, it’s an absolute must-have for any browser. Firefox could really elevate its game by taking inspiration from Vivaldi, Edge, and Arc Browser and integrating a native split view feature. (Not Firefox addons) @Laura_Chambers
:Amazing! I only wish that there was a flatpak for nightly + developer editions so I could actually test this easily

I’m not sure how the upstream version would get merged, but that sounds promising enough!
It doesn’t have to be difficult.
Just remember the TGM Tab Group Manager add-on that existed before Panorama.
I think the author was Axel Shootingstar.
That TGM add-on and the Vertical Tab add-on or the Tree Style add-on were all we needed.
Some people want Vivaldi tab groups, but Vivaldi tab groups are only nearly equivalent to TGM.
They just need to bring back the TGM tab group manager add-on.

難しいことを考えなくても良いのです。
パノラマ以前からあったTGMタブグループマネージャーアドオンを思い出せば良いのです。
作者はAxel Shootingstar だったかと思います。
あのTGMアドオンと垂直タブアドオン、もしくはツリースタイルアドオンの2つがあれば、必要十分でした。
ヴィヴァルディのタブグループを望んでいる方がいますが、ヴィヴァルディのタブグループはほぼTGMと同等の機能を持つにすぎません。
TGMタブグループマネージャーアドオンを復活させてくれれば良いのです。
My point is that just a simple top row of tabs (I don’t care where they are, but I prefer to be able to arrange them horizontally all the way to the edge of the window) for tab groups is all that is needed.
I am Japanese, so my English may not be correct, hence I leave the Japanese text below as well.
私が言いたいのは、ただただシンプルなタブの上段（場所にはこだわらないが、ウィンドウ端まで横にズラッと並べられるのが好ましい）にタブグループ用のタブがあれば必要十分だということである。
I really do hope, it will not look like this. And honestly, I doubt. Since this UI looks very much outdated. I assume it will be similar to Googles Tab Grouping approach.
I am not referring to the look of the UI looks. And I don’t care.
As long as you are comfortable with the firefox UI looks.
My preference is different from Google’s tab group approach.
It is more like the Sidebery add-on, or Vivaldi’s tab groups.
I am all for ease of use. So if you feel it is OUTDATED, you design it.
Since I have little interest in the look of the UI looks, I am fine with Vivaldi’s tab group as is.
Do you have your own opinion in terms of usability?
If it is just a matter of appearance and looks, I would like to see your design proposal.
I am Japanese, so my English may not be correct, hence I leave the Japanese text below as well.
私はUIのルックスのことを言っているのではない、言及しない。そして、私は気にしない。
FirefoxのUIルックに馴染んでいれば良い。
私の好みはGoogleのタブグループのアプローチとは異なる。
どちらかというとSideberyアドオンやVivaldiのタブグループに近い。
私は使いやすさを重視しています。だから、時代遅れだと感じたら、それをあなたがデザインすればよい。
UIの見た目にはほとんど興味がないので、Vivaldiのタブグループのままでいい。
使い勝手に関する点で、あなたなりの意見はありますか？
見た目だけの問題であれば、あなたのデザイン案を拝見したいです。
In terms of usability I hope they will add a possibility to name groups and give them a specific colour (like they do with the containers nowadays).
I hope they will add a possibility to name groups and give them a specific colour ,too.
I would like to be able to name of the groups and color-code the tab groups.
If this is the case, then my wishes and yours are not in conflict.
POPEYE, have you ever used the sidebery add-on?
It can name groups, and it can color-code groups (strictly speaking, change the icon and the color of the icon).
I think that perhaps your wishes can be fulfilled.
And my hope is that the sidebery add-on would be freed from the sidebar.
The sidebar area is too small for tab groups. That’s all.
I am Japanese, so my English may not be correct, hence I leave the Japanese text below as well.
グループ名を付けることと、タブグループの色分け出来ることは、私の望むところでもある。
であれば、私とあなたの希望は競合しない。
popeyeさんは、sideberyアドオンを使用したことはありますか？
グループ名も付けられるし、グループの色分け（厳密にはアイコンの変更とアイコンの色の変更）が可能である。
恐らくあなたの希望は叶えられると考える。
そして私の希望は、sideberyアドオンをサイドバーから解放してほしいということだ。
タブグループにはサイドバーの面積は狭すぎる。それだけだ。
What’s the word on this? I’ve used various search engines and attempted to take a look at future milestones for Firefox, but was unable to find anything whatsoever about stacking or grouping. And I could have sworn itsfoss ran an article about that feature coming soon, back in March 2024. So … are we getting this, finally, or are we not?
That article was not updated or followed-up on, since then.
