The more I think about this, the more convinced I am that I want a browser that functions like an IDE.

Multiple panes with tabs, that can be resized either to custom sizes or automatically (binary space partitioning).

It’s too much for a general purpose browser, which is how we’ve got the Chrome, Safari, Firefox we have. But I think the appeal of a more information-dense browser is broader than we think, anyone doing research would benefit from it.

Vertical tabs without nesting (trees) is such a wasted opportunity. Nesting lets you close/minimise/etc a group of a related tabs, eg. all the search results you opened from a single query. I hope Brave's implementation at least lets you switch tabs using the mouse wheel, which is probably my favorite feature of the Firefox vertical tabs addons.

BTW, I was a TST user for many years, and recently switched to Sidebery, which seems to do the same and more, but is a bit more polished.

It's strange to me how a key selling point of these vertical tabs is "save on vertical space", but they almost always still include a header bar. You can see in the video they posted that it saves almost no vertical space, while now taking up a massive amount of horizontal space.
OmniWeb (from Omnigroup, developers of OmniGraffle, OmniPlan, OmniOutliner et al) was their web browser offering in a particularly fecund period of browser development in the early 2000s, which had vertical tabs. The tabs themselves were little thumbnails of the contents of the web page in question.

I used OmniWeb as my main browser for many years, right up until Firebug and Firefox became the preferred development environment. Great browser, a lot of great UI ideas out of that shop.

I've been using Firefox with Tab Center Reborn, and a config which collapses the tabs so only the favicons are visible. Using Shift-Tab, Ctrl-Shift-Tab and Ctrl-T, Ctrl-W to go around and open/close is so logical for me. First time I heard about Tree style tabs I was so against them because they occupied significant amount of space and I didn't know you could collapse them. I don't see myself ever going back horizontal tabs. Vertical is so much better, especially on smaller screen (like 1366x768), where horizontal space isn't needed that much as vertical is.

The more enhancements I see browser vendors making to tabs, the more I think they’re reinventing bookmarks/favorites.

Safari introduced “tab groups” a while back, which to me is an insane mess of complexity. When I think about it though they’re just folders and each tab is a bookmark/favorite.

The vertical tabs in Brave remind me of bookmarks/favorites too.

I care more about having enough horizontal space to do split view than I care about having 10px of vertical space
If you think this is awesome you should check out a browser a friend of mine is building called Horse (yes, called “horse”)


The reason I like it is that he’s unified tabs and bookmarks almost, it’s a great UX that looks like some things you might have seen but still feels different.

He’s also got wicked design sense — but I’m biased so. I also feel like I’m doing him a disservice — he’s got one of those silly lifetime deals going right now.

Why do people need dozens or hundreds of tabs to the point that they need groups for them? We've had bookmarks (and folders for them) for decades... It made way more sense when you could expect tabs to always be loaded, and not behave like another set of bookmarks.
I’ve been using this on Brave dev for several months. It’s great! I hope they enable nested tabs, which I loved having in TST on Firefox.
I've had vertical tabs in Vivaldi for a little while now. I hope you guys enjoy it over on Brave as well, they change how you use tabs. Strongly recommended.
Never liked vertical tabs. Horses for courses, personal preference and all that. My muscle memory for normal/horizontal tab layouts is so ingrained in me, that using anything different would take on a huge unlearning.
This basically adresses my biggest gripe with tabs in an elegant way:

The primary input mechanism for dealing with a large amount of "list entries" in any GUI software, nowadays is scrolling. While scrolling can be implemented in horizontal tabs, browsers prevented it from being used efficiently. Tabs all have to fit on that bar, and if they don't, for some reason you couldn't scroll but had to click little buttons, or if you could scoll, it wouldve been a bad UX, since tabs horizontal scrolling goes too fast for the user, or takes too long.

Vertical tabs. Nice. From now on, any browser not offering this feature, shouldn't even bother applying. Nicely done Brave!

What I've learned trying to analyse my preference for vertical tabs is that it's not so much about saving horizontal space vs vertical space. It's more just about showing more information on screen before needing to scroll.

With regular horizontal tabs you either squeeze all tabs to fit the window width, in which case you stop being able to read page titles at some point. Or you have a horizontal scroll on the tab bar which also means you can only read so many titles on screen (probably fewer) before needing to scroll.

The vertical tabs switch this up by being able to show a larger number of tab titles before you have to scroll down. Of course this depends on the width of your vertical tab sidebar but having word wrap or configurable height on horizontal tab bars isn't ever presented as an option so can't compare.

Another clue to understanding my preference was when I realised I actually really like being able to have multiple rows of horizontal tabs vs a horizontally scrolling tab bar. So I think it just came down to the density of information visually available before having to do any scrolling.

I do think it all just comes down to personal preferences and muscle memory and individual use cases (for example, some people like having 50+ tabs open, others don't). So I am very hesitant to call one approach better. I just don't understand why we can't have both options more available everywhere.

I have just found that ‘disable JavaScript’ in Brave on iOS removes ‘Promoted Posts’ on Reddit on mobile.

So, looks like I’ll move to that when Apollo shuts down.

Works with Twitter too - I’m a noob smh.

*looks like I’m wrong- now not loading. Oh well.

The crypto wallet video ad in the middle of the article is intrusive and frankly infuriating, especially when there is no video illustrating the lifecycle of the new vertical tabs.
Anyone remember the "Compact Navigation" test Chrome did ~a decade ago? https://pureinfotech.com/how-to-enable-compact-navigation-fe...

It had a major downside of putting browser chrome over the page area and hiding the URL. Over time the latter has become the default anyways but the former is still iffy. Safari approached this concept more recently, as the only browser I'm aware with this as an officially supported option, but put the URL bar directly in the tab, which is a bit more awkward to use. On Vivaldi there is the option to hide it but then activate it via a keyboard shortcut/gesture, which functions similarly but can cause extra switching between keyboard based navigation and mouse based navigation (the latter of which can be very hard to avoid). Because of the way Vivaldi is implemented it's always performed a lot worse than other Chromium based browsers for me as well. In Firefox there were several CSS hacks for this but it was constantly falling apart on updates so I gave up on it.

I guess the long story short is: as a very light tab user (1-8 throughout the day) I miss this old option in Chrom* greatly.

Been using that in Vivaldi and it's great, glad to see i this UI feature moving elsewhere
I really liked brave and this is an interesting feature, but I had to stop using it when I tried syncing my bookmarks - for some reason, a bunch ended up duplicating, and I have a lot of bookmarks that are well organized.

Otherwise, I would have kept using it - it was fast and energy efficient on my intel macbook, way better than chrome.

I also have to say - I hate when I have so many tabs open. It's basically a manifestation of my ADHD. I need to focus one thing at a time.

Im conflicted, I like the general idea behind brave, their vertical tabs look good, but the browser deeply integrates this crypto grift and robs sites I visit and have their ads allowed of their revenue then wants them to "opt-in" to their grift to get the money they stole.
Now if only you could hide the tab-favicon sidebar...

Arc does this, but they don't give you the URL bar. It may sound nitpicky (and it is) but I really want the hidden tab sidebar AND a visible URL bar. Here's hoping either Arc or Brave will make this an option.

Firefox has tree style tabs, and no crypto. Win win
close your damn tabs, heathens
More and more I've wanted a browser based on WebKit/Blink from a company with the original Mozilla's values. I know this will get a lot of flack, but Gecko feels way too antiquated for what I want out of a modern browser. Not to mention, browsers are significantly complicated that splitting developer efforts just doesn't seem like a good idea; Firefox keeps falling further behind in term of modern features.
More browsers need to make "tab categories" available. It really helps to organize your tab clutter by topic.
Kagi’s Orion browser also has this. I like it.
A while back, I switched to just using private mode all the time, and haven’t looked back.

The main problem I have now is that I have trouble finding old stuff because internet search keeps getting worse.

Bookmarks aren’t really a solution because they are not searchable, and I’m bad at predicting what I will want to re-read in 5-10 years.

Everyone is copying Arc. Microsoft showed a similar design to what Arc has along with vertical tabs.
Vertical everything. It makes everything so easy to read and scan. I encourage vertical definitions for jr devs, especially ones tempted to put a 20 conditional if statement horizontally (no I don't want to talk about it).
Queue the incoming Mozilla and Google employees to start spewing, “Brave has Crypto!”.

Brave has been the best innovation in browsers in recent years. A pleasure to use. Kudos to them and their users for putting up with all the hate.

The Orion browser has had this for a while and has the best native implementation by far I just hope they don’t remain pigeonholed into apple OS as they currently are
Why would they do something so controversial yet so brave?
Maybe eventually mainstream browsers will get to the level of functionality of Firefox + Tree Style Tabs.

(Sadly, I can't call Firefox all that mainstream today.)

Love it. Vimiums keys for switching tabs are reversed though. K goes down and J up. Still easier to remember than which one goes left/right.
No tabs is my preference https://iili.io/Hrtppup.png
Have been using same via Chromium Edge browser. I also like workspaces feature. It's very handy to give some context to the group of tabs.
I tend to dock my windows taskbar left for the same reasons and I'm not upgrading to 11 until they let me keep that.
Ngl, I'm digging this feature.
Looks like there’s no tree functionality. I’ll be sticking with Orion for the time being.
Arc has been using this approach from the beginning — https://arc.net/gift/a192125e (here's an invite for whoever would like to try it out).

The more I think about it — the more Arc reminds me of an IDE. A browser IDE of a kind.

Nice. For some reason, vertical tabs just have never taken for me.
It looks nearly identical to Edge's vertical tab.
Why use brave when Firefox and Chrome exists?
Tabs are entirely useless and wrong abstraction. Look at VSCode, you just use Command Palette to search for anything. That's good
aka bookmarks
no tab preview like old opera? That was like my favourite feature
Brave gives a very bad vibe (mostly due to the affiliate links scandal), I prefer to just use my favorite browsers (ff/edge) + uBlock Origin and Privacy Badger which give good privacy/adblock experience, are open source and customizable to my liking.
I was waiting for the 'Arc'-ening to happen.
Now all it needs is pie menus (like in Blender, The Sims, etc) that you can pop up by clicking on the tabs, and it will be as fun, efficient, and easy to use as UniPress Emacs was in 1988!

I later implemented pie menus and tabbed windows for the NeWS Toolkit (TNT) "Open Look" window manager in 1990 for Sun OpenWindows (X11/NeWS), that let you drag the tabs around to any edge of the window, and wrap all your windows in tabbed frames, even including X11 windows!

I see the name “Brave Browser” and my brain just refuses to engage. Their marketing team ruined the product for me before I ever got the chance to try it.
