This is great to see. I used this feature when I had Zen browser installed. What this really solves for me is the pain of using two Firefox windows side-by-side with vertical tabs. Every time I move my cursor from the right window to the left, the tab bar opens and stays open. This would solve that problem. It also saves the small cognitive load required to open another tab and move it into split view on whichever OS I happen to be using in that moment

What is it with you people.
Everyone crying firefox should stop adding AI features and focus on ui/ux experience.
Firefox adds ui/ux feature
3/4 of the comments complaining that they wont use this specific feature that was added
Do none of you understand the world does not revolve around your use case?

Good for you bud.
But I don't want to right now.
In contrast to the downers, I'll really like this. Dual monitors with a terminal or whatever on one and now I can have two tabs easily visible without much work on the one screen. I'll take it.
Yeah same
I honestly find the FOSS communitybpart of lemmy really exhausting the last couple of months. Everything and I mean EVERYTHING is met with so much hostility.
Completly incapable of seeing any nuance
Quite frankly I find more than half of Lemmy in general has a lot of hostility and very little nuance. Very much agree it's exhausting.
Anyway, glad to find someone else being excited about this feature.
that's because you're a genocidal pos
I've been using it for a month, I really like it. It's a feature I remember fondly of when I used Vivaldi like 8/10 years ago. I hope the released implementation includes an "open in split view" contextual option on links
Seems a bit redundant when you can just use split windows no?
Window management has barely improved in decades in mainstream OSs. We've got snapping in Windows and macOS* but that's only useful if you want your two windows to take up the total screen real estate between them. Others, you're manually adjusting both windows - it's messy and not ideal.
*I've only used headless Linux for a long time, so I don't know what the scene is over there.
Give me a second...
Yup. My system still supports multiple things at once.
Perhaps this is for psychopaths that maximize every window?
Try doing that on mobile.

Well... technically, they're not side by side
Your moves are weak.
How is this any different than just having multiple windows open? Maybe a slight performance savings over running 2 different processes but I can't immagine that amounts to much.
Depends on your workflow. I find this feature useful when I have multiple tabs open and need to switch between them, but also need two different sites open side by side. If I switch a lot between the tabs, having two windows open becomes annoying pretty fast as I want my main window to be maximized. This is a non-issue if my second monitor isn't being used for something else, but it often is.
I use this a lot (on Zen browser); It's pretty much the same thing as having two windows, but I find it a lot more practical in general.
Zen is not great about having multiple windows open, which is a non-starter for multi-monitor setups
I guess it really depends on how you use the PC. I usually have 7 or more active programs at the same time so I avoid opening extra windows.
They did add this bizarre new feature that syncs tabs between windows though. I still can't wrap my head around why someone would want this.
Firefox is already multi-process, so it probably won't change Jack shit in that regard, either. And even when it was single process, it was a process for all open windows.
Mobile won't permit you to have 2 windows of the same app open just because you want that.

Whoop de doo. Or you could just open two browser windows. 🤷♂️
Def can use this while running my dnd games
So they added this feature to desktop, but as far as I can tell not to mobile, where it would be genuinely useful? Especially in the age of folding phones.
Finally catching up to Vivaldi.
So amazing. So beautiful. So... what?
KDE's Konqueror had this for .. decades, I believe.
It means that no matter what size display you've got, if you want to do side-by-side comparison on ONE site you're visiting, then you split the window for THAT tab.
You don't need 2 windows, with all their menu-bars, widgets, borders, status-bars, etc, duplicated.
Much cleaner.
On small displays, it's wonderful, for comparing information between 2 pages/sites.
On mobile, it's impossible to have 2 windows of Firefox open simultaneously.
& 1 of the above commenters pointed out that they're only doing it where it doesn't really matter to most, on the desktop, but NOT doing it where it's NEEDED, on mobile.
Typical Mozilla, in my eyes.
Too-frequently solving the wrong problem, enacting the wrong "strategy".

All jokes aside, it's really not that important. I'm glad you're excited about it though.
He's not. He just seems to be looking for Mozilla-related posts and diarrhea blasting sardonic comments on them.
