Should be baked directly into the browser instead of AI BS

★★★★★ This Extension Unlocked My Inner Productivity Maniac

Okay, full disclosure: I'm the kind of person who has approximately nine billion tabs open at any given time. This extension didn't just help with that; it fundamentally changed how I use my computer.

The basic idea is brilliant: your main page is front and center, and any link you want opens in a sidebar. No more tab switching madness. It's flawless. I can keep a research paper or a tutorial open on the side while I work. I honestly don't know how I lived without it.

But then I fell down the rabbit hole. I discovered you can open a second, completely separate Firefox window, give it a sidebar, and then use Windows' snap feature to dock the first window to the left half of my screen and the second to the right. Boom. Four fully interactive, always-loaded websites on one monitor. It completely defeats the browser's "memory saver" that always unloads my dang tabs—because everything is technically "visible."

And the magic isn't just for browsers. Since Windows lets you snap almost any window side-by-side or into the corners, the combinations are endless. Imagine: my main research tab on the left half of the screen, with a YouTube guide playing in the Side View sidebar. Then I can snap a Discord call live into the top-right quarter, and my notes app into the bottom-right quarter. Three different apps, one screen, no switching. I can even adjust the Side View divider to give more space to my research or the video, on the fly.

Now for the bonus, "this-is-probably-overkill-but-I-love-it" round. I realized that instead of just left/right snapping, you can drag windows to the four corners of your screen for a 2x2 grid. So, theoretically, on one giant monitor, you could have four separate Firefox windows, each with its own main page and sidebar. That's EIGHT tabs on one screen! With two monitors, you're looking at a ludicrous 16, and with three... a frankly ridiculous 24.

Let's be real: unless you're working on a stadium Jumbotron or an 8K monitor, actually using a setup with 8 tabs on one screen would be a recipe for squinting and frustration. It's a fun party trick to think about, but not terribly practical. But the fact that the extension allows for this kind of insane flexibility is just cool.

For the realistic use case of mixing a few browser windows with other apps, or just having 2-4 pages on a screen, though? It's an absolute, no-question-about-it game-changer. If you multitask for research, coding, or even just comparison shopping, this is a must-have. It feels like a superpower.

работает на ура!

The side view in Firefox is an awesome built-in feature for switching tabs. It makes managing tabs so much easier and more organized. I really hope this feature stays and gets improved in future updates of Firefox!

The add-on is a perfection.

What would be nice to improve:

1) if Firefox Multi-Account Containers is used the session should be duplicated into the side view container as well.
2) No way to open browser extension (like Browser Notepad) in the side view

This was what I was looking for! #firefox4ever

Just what I was looking for. Thanks!

Finally! I have been waiting for years for the devs to allow unrestricted width of the side view. It was fixed at a ridiculous small width. Why did it take so long!?

It's good but it makes YouTube Music a little bit buggy.

Apart from the pop-up URL menu not applying dark mode based on the theme, everything else is great! Moreover, with the new sidebar design, the user experience is close to that of a browser that supports window splitting!

Really like this addon. Please take a look at what zen-browser is doing with splits for further inspiration.

Thanks!
