I never got vertical tabs, I just feel like I’m loosing screen real estate. For managing a lot of tabs I much prefer the Simple Tab Groups extension.
Which website actually has a layout that makes use of your extra space, and doesn’t center the content with empty space on the left and right side? I actually have barely ever noticed a case where it was useful
YouTube for one, and if you were to place two windows side by side you’d loose a lot of space on duplicate tab bars.
Not sure what you’re actually losing on YouTube though… You go fullscreen quickly anyway. And if I put two windows side by side I just disable the tab because I’m likely doing it for a reason to have two specific pages on them, actually giving more screenspace because I don’t have the bar at the top either.
that’s interesting because frankly I feel the opposite.vertical screen real estate is at a premium, it’s already common to have a horizontal taskbar and/or menubar eating into the desktop space, and then any browser UI like address bars eat into it more. Meanwhile most websites I visit are filled with whitespace on either side and always require scrolling down, often infinitely scrolling down, so the more vertical space the more you can fit on screen without scrolling.
To put it another way: I rarely full screen my browser because making it wider doesn’t help, but I usually have it filling the maximum vertical space. Granted I’m on an ultra wide making this problem worse, but even at work on a 16:9 I feel the same way
